| [#1] Will U toe-in differently for different CDs/music? Not all music / cds are created in the same conditions. I have yet to learn how music/cds are made in different studios / for different genres / by different mixers / engineers / with different gears (monitors with different toe-in angles) ... BUT it seems true to say that different types of music / CDs are made under different human, acoustic and material conditions. SO ... Would you toe-in differently for different CDs? Sometimes we blame some particular CDs as bright, but would it be the case that the engineers produced them with like, 20 degrees toe-in, and we have 30 degress toe-in? And would it be the case that the enginner is mixing the music in a small studio (which tend to be popular music?), and what our listening place is actually larger than their studios (e.g. 5 fts apart) so their sense of 'balance' of instruments - real or synthesized - has totally lost and become flatted once we listen to these CDs in our larger listening space (like with speakers 8 fts apart)? I have started to wonder if there is only the SINGLE, CORRECT speaker placement for differnet CDs/music. Please share your views if possible. |

| [#2] Will U toe-in differently for different CDs/music? If your listening environment is set up correctly with appropriate acoustic treatment to reduce any possible phase cancellation caused by unknown reflection from somewhere within the room, you should never need to try different toe-in angles for different music/CD. Majority studios monitoring set up with speakers placement put in a fixed position in almost equalaterial triangle between speakers and the engineer, and ideally studio monitor speakers should be direct line of sight to the engineer listening position. (Note, professional monitoring speakers are generally very accurate and neutral in producing sound but lack the sweetness of audiophile speakers through colouration) In the home environment, this is somewhat different because of speaker design, size of speakers used etc. There are too many variations and combination which are available to even disguss here. ( I know the fact some audiophile speaker design uses phase alteration within the cross over design to enhance the sound to make instrument stand out more and give you this 3D feel - I will not mention brand name ad model here, but this may cause problem in some listening environment which may be out of ordinary shape or object placement within the room such as lounge chairs , TV, and even book shelves). May I make a suggestion, try to group out some of the music/CD that gives you simular toe-angle and almost neutral irrespect of those angle versus those CD/music which create strange placement and which require adjustment, from this exercise, I hope you may be able to hear certain frequency range (i.e. voice or particular instruments that cause the difference etc etc). This relationship may tell you something you may not realised before, this, you can begine to solve your problem. Having done that, to go further into the investigation, you may need some help from the genuine professional to use pink noise and various tone test to find out and identify the problem area for you. At the moment, I personally cannot tell you why you need to adjust the speakers toe in constantly unless there is some environment within the room issues that require you to make correction constantly. (i.e. irregular shape listening environment, but what I wrote in the above paragraphs was I assumed your listening environment is regular rectangular shaped room to begin with). I hope to hear your findings using different music and also some other blog friends may be able to share their view. |

| [#3] Will U toe-in differently for different CDs NAR, first, I have to say thank you for your informative and thoughtful suggestions! Your point about special design of speakers is really interesting, and the 'grouping CDs which give or don't give strange effect' is also very insightful as well. My room is 12 x13 x10 (H), regular. Speakers placed around 6ft 6inches center-to-center (of the speakers). Before I do more serious comparison test, I would like to say further my general impressions - which are probably not true but may well be food for thought. For more seriously recorded music (like audiophile recording), it seemed I have yet to encounter the problems I mentioned. I did experience some problems when listening to more 'popular' recordings. When I encountered these popular music recordings, yes, the effect of 'phase cancellation' seemed to emerge, which means I either had to place the speakers closer to regain a more balanced sonic structure, or got more toe-in to make the sound sharper. I have to say the latter method wasn't the best, and closer speaker placement was better, and bring more life to those popular music CD (richer body, bass regained, and so on - but of course it won't cure the average / below average recording of those CDs). This led me to think if some mixers in did their work hastily and made me feel that way. But as you said, there're so many factors here, and my proposed explanation may be just a spurious one :) And I still listen to those CDs since I love the music within - too much music I love is not recorded well, how depressing! |

| [#5] Will U toe-in differently for different CDs You are using B&W speakers right ? ^_^ If you are using a B&W with a under-powered amp, then you can feel the sound image comes out and very directional. If you use a more friendly speaker with a well-powered amp, most likely, you cannot tell the imaging of the treble. It may be unrelated, but if your amp is good that can control the speaker well, you would have fantastic imaging. |

| [#6] Will U toe-in differently for different CDs One more thought: What is behind the speakers may I ask?(i.e. wall? windows? curtain?) First of all, I make the following assumption: (1) The amplifier is fully match your speaker which is well damped, sufficient power to handle various music (2) Both side walls decor are very much the same without any object that may affect the sound which make give strange reflection if either have different object placed along side (This I assume is not the case). (3) You may have a rear blank wall or something that can reflect the sound. (This may not be important for B&W speakers but a blank and reflective wall is needed for electrostatic speakers such as Quad etc.) (4) I am not sure which model of B& W speakers you are using, but is there a port at the back of the speaker. ************************************************ Having considered all the above, now I like to show you how I would set up speakers for my own enjoyment and of course the following technique may be used for your reference as well. Let do some more test. Do you have any recording such as Louis Armstrong? The reason for this is the recording of this kind usualy have a very strong vocal (center image) which you can use as reference. Some other recording of simular nature will also work. PLEASE THE SPEAKERS PARALLEL TO THE SIDE WALLS FIRST WITHOUT TOE-IN (BEFORE YOU DO THAT, MARK THE ORIGINAL SPEAKER PLACEMENT FOR YOU TO GO BACK FROM START) VOLUME LEVEL SHOULD BE SET AT COMFORTABLE LOUDNESS SO YOU CAN HEAR EVERYTHING IN THE RECORDING. Step 1: Start the music and assume you have blank wall behind speaker (or open your curtain if they are closed). Stand between the two speakers in axis to them facing the rear wall. Listen to music is they give you a sharp, clear reflected image. Mark the original speaker position (so you can restore where they were before) and move them parallel along the side wall closer or further away from the rear wall to see if you get a strongest vocal image while you follow the same axis in between the two speakers with you facing the wall behind the speakers. (Mark the speakers postion again) Step 2: Turn around and face the listener's chair in same direction as speaker, get someone to move the speakers towards you or away from you to get the strongest well defined vocal image (Center image) STEP 3: Make sure the listening chair is placed at the center axis of the room. Move the listening position up and down along the center axis of the room until you get the clearest sound image. Step 4: Toe - in the speakers to suit the listening position. Unfortunately, we are not too good in fine tune the toe-in angle exactly, therefore I normally stick a masking tape on top of the speaker at center axis front to back on both. I use this masking tape as a accurate alignment guide to the aiming angle of the speaker to toe -in position. Initially, I started the line of axis of toe-in according to the alignment guide (masking tape) and point each speakers to the left and right ear of the listeners and fine tune from there. [There is no absolute rule to how much toe-in angle should use, but the listener had to use the imaginary mouth size of the vocalist as a guide for toe-in.] I hope the above information help you to improve your hard to define sound image. I use simular technique to my own speaker placement and worked well. I must admit I am not familiar with the B&W speakers so I am unable to provide further help to you. Happy Listening. |

| [#7] Will U toe-in differently for different CDs The reason using my method is let you find a coherence of left and right channel at the center of the room in between 2 speakers. This is the fundamental to get the room acoustic correct first and irrespect to what room acoustic you have, the method to by standing in between 2 speakers will determine the sound being properly reinforced in your room before you actually sit down to listen to the music. Fine tune the speaker placement to further enhance your enjoyment is what I always believed in. I wish I can tell you more but I can't because this is the only way I know how to setup my own speakers. |

| [#8] Will U toe-in differently for different CDs Kenny hing, I am not using B&W speakers. I am using Monitor Audio, and my power amp has 250W, strong enough to push them :) (not overpushing, as my speakers doesn't sound good below 100W). Regarding the rear wall. It's a mix of shelves and 2 doors - some sounds inevitably escape. It should be tend to be the higher region as I closed the door, the sounds were duller. But there are first reflection points behind the speakers which i will treat them with some draped curtains later. I think it may increase the image. The room is unevenly decorated. But I tried to use things to block the first side-reflection points of both speakers so I think it shouldn't be a problem. I also used vocals to find the better position - I said better since I never have exhausted the possibilities as seriously as you suggested. But I did experience the kind of 'slightly-toe-in-makes-a-huge-difference' thing :) NAR hing, I will CERTAINLY follow your suggestionS once again to see if I can find a better sweet spot! Still, I see recording has a role to play here, since I tend to believe there is a vast difference between different studios, enginners and music. Have you experienced some CDs that doesn't give you the tonal balance you want YET many 'STANDARD' CDs (audiophile type) are excellent in your system? This is why I ponder the mixing / production of those CDs might not 'match' your system (a blunt way of saying is those CDs are produced bad). Some Cantonese CDs, for example, lower the vocals so the vocals become too 'light'. I could either tune the vocals by use of tone control / equalisers. And what I am saying here is another method - bringing the speakers closer, which gives a denser body of the songs. What I lose is the soundstage width. Certainly the best way is probably throwing those CDs away, but as I love the music within the CDs, I have to find a way to listen to it in a more pleasant way ... |

| [#9] Will U toe-in differently for different CDs I know there are so many sub-standard recordings out there and still dare to claim hi-end recordings. Not all engineers and studio engineers worked in are the same although professionally speaking, there is a certain standard to setup studio monitoring speaker system all studio should adhered to. I know because I had been a recording / mastering engineer for years. Compression is often needed for radio broadcast and CD production, some even involved in the loudness war which I am so against but this is where the trend is. Overcompression will ruin the naturalness of sound while worked well with most sound system. Added Hall effect smear the accurate instrument placement of an orchestra in a recording and often used for cover up use. This type of subject is something I should not get into as everyone has their own taste of music. ********************************************** Uneven decore in your room may not help the sound but the method I showed you will certainly help. Once you have the sound image corrected, then you can apply suitable EQ to make sound more refine to suit your taste. Raymond |

| [#10] Will U toe-in differently for different CDs NAR / Raymond, thanks for your reply. Uneven treatment ... sigh ... most of us have their gears at home and this is somehow inevitable. The problem can only be alleviated but not eliminated, at least for me and some of us here. I'll try my best. This said, I often dream of having a domestic envirnoment which is very warm, not hifi look, but sound good. This is probably a dream or achieving this has to alter / set up infrastructure of the acoustic envirnoment in the first place. Your setup guideline is actually very detailed, and a second read is more revealing. I'll try my best to find some time to experiment. NAR hing, could you recommend me some really 'reference' recordings? I came across too many articles saying this or that as reference recordings. I used to believe there are some definitive recordings, but the more I listen, the more I am confused. First of all, by what judgement one recording (I only listen to CD and am trying to setup a decent CAS system) is said to be 'reference', in what specific listening circumstances? For example, some said A is a reference recording, but you find it doesn't play well in your system. Yet you find some sound nice / good in your system, but they're hardly quoted as reference recordings. All said, I am left to judge how good my system is, and I need some yardsticks. NAR hing, you're an expert in audio production, would you recommend some more universal good CD recordings for judging performance and setting up a yardstick by which I judge other recordings being played in my system is good or bad? Without this yardstick, I feel like chasing ghosts. |

| [#11] Will U toe-in differently for different CDs Dear NAR (Raymond) Nice to meet you in here :) And thanks so much on the advice on loudspeaker positioning. You almost make me return to repositioning mine at home :) I think your detailed description should be included in every loudspeaker instruction book. Regarding professional monitors and domestic loudspeakers, it appear to me, that pros working in studios are not 100% relying on listening to the programme they are working on; and even when they do, they often listen at a low level, much lower than average domestic levels. During my brief radio days, we also tend to monitor at low level when doing voice programmes such as interviews and news, be they live or recorded. I did not belong to engineering (I was only a writer turned news reader ...), I was just "plugged-in-position" after things were ready set up, and so to me, monitoring at low level had become more of a taken -- been there, done that, but I never have a good understanding except to avoid listening fatique. I appreciate you, as an recording expert, would share a little more your experience with us :) And even to today, I still tend to listen at low level, so low that for example, I almost have nothing audible in the first 15 to 30 seconds for Ravel's Bolero (depends on the conductor, symphony, recording, etc ...) at home with a not so low noise floor, just to make sure the explosive ending would not intimidate me without turning down the volume during the session. I get used to this, but my wife always says, having Bolero with me at home is a test of patience, waiting for the first note to come ! ----------------- Perhaps the toe-in issue would bring us back to the origin of two channel stereo and microphone positioning. I was told, that two channel stereo started from the Paris Opera House in the late 19th century, when telephone was about to take off. There pick-ups were lined up along the opera stage, connected to the exchange, and guests in dedicated hotels can hook up to listen to the performance through a one-way telephone. This could have been among the first time people could enjoy a performance without showing up in the real person, and it became quite a "chic" among the trendy people then. Soon enthusiastic listeners in hotels found that if they picked up two phones for both ears, sometimes they got a curious experience of having a "hallucinating" sound effect. They then began to hunt down those particular pick-up pairs on stage that would give the most pronounced effect, and the rest is history ... |

| [#12] Will U toe-in differently for different CDs Dear All, This thread is really interesting as it raises the bar for R33 for serious audio discussion. Personally I don't know the physics and the theory behind this subject but I do toe in the speakers from time to time. My action is mainly trying to achieve a "correct" soundstage for the records I am playing, be it orchestral recording, live recording(different scale) or simple solo acoustic recording. My meaning of "correct" doesn't necessary reflect the actual image when the music was recorded, rather my personal perception of what I like to hear. May I thank Raymond for his detailed explanation for this subject and I would also like to second the notion by notmychartwell that the detailed description should be included in every loudspeaker instruction book. I found this article may be useful for this subject: "Speaker Placement by Galen Carol". http://www.gcaudio.com/resources/howtos/speakerplacement.html |

| [#14] Will U toe-in differently for different CDs Dear All, I was only a casual visitor to the blog yesterday and saw zbigniew821 is in need of some help to get his speaker sound image better defined, so I dropped everything and start typing. As I am having a day or two free from my work to write, usually people do not find me writing much on any blog as I do not have much time to do that in regular fashion especially getting used to 12 hours of work a day is becoming rather tired after a while. As 'Notmychartwell' hing mention about listening to music at low level, he is absolutely right the way to test the sound system because many top notch audiophile gear will give you this proper sound stage, detail of music irrespect of the volume level while the lesser quality gear will fall apart in almost everything at soft level. This is a good test to separate 'Men' and 'Boys'. I too cannot subject myself to high SPL all day while working, so I do most of my work at low level and raise the level during evaluation. As to some of the better recordings to check your speaker placement, there are so many out there but I had been doing only classical recording for the past 8 years only for large orchestra and therefore I am rather out of touch with good recordings which are available today and I guess you fellow audiophile would make better suggestion than what I may suggest here. My suggestion is some of the better Louis Armstrong recordings, where his voice is always at the middle and accompanied instruments are always at left / right and also at different level od loudness, this was the way they used to record. However, not necessarily my cup of tea in recording technique but 'Armstrong's" recording is very useful for setting up equipment. There are other recordings such as the Sheffield Lab Test disc and I cannot remember which one also has left right and center test with 3 people speaking all at once and also as individuals, this is useful for 'zbigniew821' - Hing and may I suggest this. Sadly I cannot recommend my work to anyone because of the copyright issue with my client. They are all very good test CD for uncompressed full orchestra dynamics with nothing added, not even artificial hall sound is added as found in many many commercial CDs. The stereo width, depth, orchestra players sitting positions are all better defined as there is no compression added to ruin such image the recording is done in an unusual fashion different to ost commercially recorded multi-mic recordings which may not be everyone's cup of tea. Sadly, not many CD players can handle such high dynamic recordings and because for non-commercial release therefore no mastering is done making sure everyone can play those recordings for commercial release. I rather not say anymore in the field of work that I do because it is no relevant to many of you out here. zbigniew821 Hing, just give me a bit of time to search through some of my collection of commercial release CDs dated back many years ago and if you have those recommended disc, use them for you speaker alignment and this will help. Being a professional guy, I also use mono recordings or if your player have mono switch, you can also use mono playing to further fine tune you speakers. This is all I can do for you for the time being, feel free to write, but I may not be able to reply immediately, however, I promise you to find some of those I believe are good recordings so that you may use them for problem solving. cheers, Raymond |

| [#15] Will U toe-in differently for different CDs zbigniew82 Hing, I found the following CDs in my collection which I used to align my own system many many years ago. I am not sure whether you can still buy those CDs but to me they were very useful tools. I hope some of your audiophile friends may be able to help. The Sheffield Lab collections: (1) The Sheffield / XLO Test & Burn-in CD 10041-2-T (2) Sheffield / Coustic Test & Demo 10040-2-T (3) Prime Cuts: Gourmet Selections from Sheffield Lab 13333-2-V Others: (4) Jennifer Warnes ; Famous Blue Rain Coat (note the original CD release is preferred but the 20th Anniversary CISCO re-release Gold CD is OK too, I did not really compare the sound quality of the two CDs in any AB comparison but for speaker alignment and the general continual sound wrap around across the two speakers test is what I am interested in). (5) Most of the Eva Cassidy recordings are very good. (6) I still suggest the old fashioned recordings of Louis Armstrong because of its strong center image placement between two speakers. Toe-in to form the best mouth size of Armstrong. Remember, I am only suggesting those CD as tools to help you set up speakers and not as comparison which CD sound better or more hifi than the other. I cannot recommend any classical music to you because I am afraid to say I am rather biased towards my own work. Therefore I rather not make comment from this, however, if it is a must, may I recommend the Telarc recording of Carl Orff - Carmina Burana Raymond |

| [#19] Will U toe-in differently for different CDs Being a professional guy, I also use mono recordings or if your player have mono switch, you can also use mono playing to further fine tune you speakers. ................................................ Hi Raymond, As you know I am not a professional, according to our good friend Master Kwong during his visit to my home, he also used a mono recording to fine tune the placement of my speakers. Here is my posting back to Dec 2008 Suject: I learnt from Mr. Kwong Dear c-hings, Due to the limited listening environment, the major problem that of my system is unable to present a reasonable size of soundstage from playing large scale classical music. It congested sound in the center between the two loudspeakers. In order to fix my problem, I asked Mr. Kwong for help. The following is a re-called from my deteriorated memory that I learnt from him during his home visit. Please forgive me if I make any mistake. Mr. Kwong came to my home with 2 CDs: (1) Stokowski RCA Victory Symphony LSC-2471 and (2) Nat King Cole Greatest Love Songs. Mr. Kwong started the diagnosis with the first track from Stokowski, within 10 seconds, he asked me to move the loudspeakers further apart from my originally setting by 12 inches, and then repeated the Stokowski a few more times. We settled down by 15 inches finally. The distance between the tweeters is being increased from 64 inches to 79 inches! From my observation, Mr. Kwong used that classical music to define the placement of loudspeakers, allows to present a reasonable size of soundstage, in order to accurate the positioning of musical instruments and improve the tonal balance...etc The next step is to define the toe-in angle; Mr. Kwong used the track no. 3 Autumn Leave (mono version) from Nat King Cole Greatest Love Songs. He asked me to turn off the power amp for left channel, and let the right channel to sing only. We repeated the Autumn Leave 15-20 times with de/increasing the toe-in angle. Finally Mr. Kwong asked me sit down listen; WOW…the music is so clean and clear, it comes from the drivers directly without any refection neither from the wall nor the furniture! We did the same process for the left channel; you know what, the toe in angle was being increase from 5 degree to 25 degree…it is hard for me to accept this change at the very beginning! However the improvement is unbelievable, the musical instruments are no longer congested at the center, now they spread from left to right in the soundstage with good scale and positioning. The loudspeakers are totally disappeared, yes they are totally disappeared! Especially, the drum is so clean and detail, no more muddy bass; it is getting closer to what I hear from concert hall. The bonus is Mr. Kwong further improved the tonal balance in my system from fining tone the setting in the EQ! In the last two weeks, I did try 30+ different loudspeakers placement, after the long and tire experiments, I am settled down from using the master setting by Mr. Kwong! Hat off to Mr. Kwong!  |

| [#20] Toe in speakers There is no need to worry too much about which CD is best tool to do the job as long as you have one of the test disk that help you to set up the stereo width without boomming sound. No ill effect of hole in the middle, mouth size of solo singer is in proportion to the rest of the band or orchestra. When you toe in too much, you will hear overlapping sound from left/right channel being cross feed too much (i.e. left signal leak into right side, right leak to left and this make the otherwise sharp and well defined center image becomes wider again. I am not sure about demagnetize CD. I thought they do not use iron material that can easily magnetized. Unless you have a very strong magnetic force from the side of the laser base and very close to it, the laser beam being so close to the CD surface, I personally cannot possibly see how the the laser bean will get affected. To me, try to demagnetizer the non-magnetic material such as CD may be a waste of time. [Unless someone can provide me more scientific evident that CDs need de-magnetize, at the moment, I am rather sceptical on this.] It doesn't matter whether you are a jazz, classical, modern pop stuff which you like to listen, setting up speakers to play your favourite music to sound right has to be an art, when you get it right, it makes everything worthwhile. For me, I do not care whether you are using a multi-million dollar system or a few thousand dollar system, the system set up are basically the same. Thanks 'hiphopzz hing' for reminding me "mono out of phase" is also needed for speaker toe-in tune. 'hiphopzz' had unblocked some of my blocked memory. It had been too long since I did a speaker tune, proper procedures become rusty for me. Thanks Naim-Man for suggesting Speaker Placement by Galen Carol. I will try to look into this with thanks. Lastly, I learnt from acoustic engineer many years ago, he used to measure a room in detail, scale a drawing of the room, he then place the speakers position on the drawing to some fine detail. He used ruler to draw lines at different angles from each speaker and the reflection of this line from the flat side wall, the listening position of the key person, more lines are drawn for direct sound from speakers as well as reflected sound off the wall to see if there is any relationship from resultant phase cancellation. He told me he had use a formula to accurately show the phase relationship with respect to certain frequency. With added objects around the room may complicate the calculation abd render the the result inaccurate. Therefore science does play an important role to our enjoyment of music. What I am saying here is when an experienced engineer may not be able to solve some of the out of ordinary (complex) issues in acoustics, what chance do we have to correct some of the issues that we had. Therefore, go back to the basic and try again to get right. However, what I noticed most audiophile (including me) are greedy, we tried to get more and more from tuning the system until a point of perfection, but the greed cuts in and because we did more and end up ruined everything we did best and had to start all over again. So when we get our system to sound acceptable, it is time to hands off and start to enjoy the music you love from this point on. I speak of my 50 years of audio experience as an audiophile. Raymond |
