| [#47] Speaker 有氣孔反射VS密封式? ＞＞＞其實氣墊式, 內埋有咩"kin 坤"呢? 可唔可以比d相片參考下? ＞＞＞ funkyshits 兄： 氣墊式內和一般喇叭都係吸音材料，乾坤在於低音單元的fo值和Q值在入箱後，和箱體內的空氣彈簧配合得剛剛好。  |

| [#48] Speaker 有氣孔反射VS密封式? 由我玩hifi等一日到現在. 總共有3對完整既speaker都無賣. 賣都無人要. 令外有對Altec Lansing-309e同軸單元, http://www.altecpro.com/pdfs/vintage/SpeakerAndMics/ceiling/309%20series%20Ceiling%20Speakers.pdf 值得買音箱去重組佢地嗎. 上次搵左個舊音箱試, VOCAL同音場都好好聽. |

| [#49] Speaker 有氣孔反射VS密封式? Odie99兄： 其實在小家窩居是旦一對都聽得過(我還講漏兩隻MUSE 18超低)，鬼叫我鐘意研究喇叭，越買越多，我都賣走左d啦，包括JBL Olympus S-7, Tannoy Arden, ATC-100, Westlake BBSM-6VF ,KEF-107 series 2, Mirage M-1si..... |

| [#54] Speaker 有氣孔反射VS密封式? 空氣彈簧?? 是指海綿? fo值 同 Q值 是指低音單元入箱後, 箱內空間同壓力??(我估架咋) |

| [#55] Speaker 有氣孔反射VS密封式? With modern engineering and material science at their best, there is no straight answer to whether acoustic suspension or bass reflex design is superior. There are all sorts of speakers with different design that all sound wonderful. To mention a few, magico, an acoustic suspension design, kharma, bass reflex, electrostats like quad, planars like magnepan, are all great speakers. At the end it all comes down to personal preference, my favourite is the gigantic electrostats, unfortunately my place is too small to house even the smallest quad so I am happily sticking with a pair of bookshelves. 孟波兄 : Inside the acoustic suspension speaker's cabinet, is the air pressure suppose to be higher than normal atmospheric pressure ? thanks. |

| [#56] Speaker 有氣孔反射VS密封式? funkyshits 兄，空氣是有彈力的，和箱內容積有關。 fo是指單元在自由空氣內的低頻諧振頻率，入箱後會提高(密封箱以foc代表). Q值是指對諧振的控制和衰減能力，數字越低(如Q=0.5)越強，Q=0.7約等如低頻在的音壓電平和中頻level一樣。 |

| [#58] Speaker 有氣孔反射VS密封式? t4455兄： ＞＞＞is the air pressure suppose to be higher than normal atmospheric pressure ? ＞＞＞ If the woofer's cone don't move the pressure inside box is equal to outside, if moves out the pressure would be lower and moves in would be higher.The air pressure acts as spring parallel with the suspension elements of woofer. |

| [#62] Speaker 有氣孔反射VS密封式? 孟波兄 : A stupid question. Any air pressure limitation when woofer move in? Or the woofer easier to reach limitaion much more than the air? |

| [#63] Speaker 有氣孔反射VS密封式? funkyshits hing, You imagine that the air pressure eqaul to a spring added with the suspension elements of woofer, the result would be: 1.Limited the movement of cone. 2.Incresed resonance frequency. 3.changed Q-factor. |

| [#64] Speaker 有氣孔反射VS密封式? thanks 孟波兄 x2 Let me ask another silly question. Most of the speakers I like either has no box (like my favourite electrostats) or has super heavily built cabinet. The one thing they all have in common is the absence of cabinet vibration. Now imagine we built a very rigid metal frame with steel or aluminium (or titanium) tubes the way modern racing bicycle frames are built, we nail the frame to the floor, side and back wall, install the speaker drivers to the frame. This way nothing but the speaker's diaphragm moves, and they move freely. Let's leave the crossover part alone and say they are designed properly. How do you think will it sound ? |
