| [#4] 新人 剛買了 subwoofer 怎test? """we usually set 4-5 db louder""" who are "we"??? all channels should be equal. only kids want disco bass. """the phase usually at 0"??? not sure about that. phase is dependent on the sub and your seating positions. one needs to tune the phase to hear loudest and take that as the correct phase. 最後修改時間: 2013-05-19 22:49:42 |

| [#5] 新人 剛買了 subwoofer 怎test? ＞phase is dependent on the sub and your seating positions A common misconception but Incorrect. Phase setting depends on the design of your main speakers. |

| [#6] 新人 剛買了 subwoofer 怎test? typo...it should be AV not AC my sub is MM6 i set my sub to "bypass" and let my AV pre amp to handle now i set all front centre and rear and sub to 70Hz, it it ok? i use SPL meter to adj. all the 5.1 channel to the same db. pls. advise the above setting is it ok? BTW, the sub vol. itself , i only turn on at 70% shall we need to turn off the sub after finish?? |

| [#7] 新人 剛買了 subwoofer 怎test? """Phase setting depends on the design of your main speakers. """ that relate to integration of the sub with front LCR. u cannot ignore the sub and seating positions. |

| [#9] 新人 剛買了 subwoofer 怎test? oh if u are using spl meter make sure when calibrate the sub the reading can be -3db. say volume level of front LCR is 75db the sub should be 72db. this is due to the insensitivity of the meter when showing 72db the sound level actually is 75db. check the correction chart of your spl meter. |

| [#11] 新人 剛買了 subwoofer 怎test? phase setting::: speaker design and relative position of those speakers..but almost not related to seating position for the integration .. 最後修改時間: 2013-05-20 13:55:29 |

| [#12] 新人 剛買了 subwoofer 怎test? """...but almost not related to seating position for the integration ..""" almost? either yes or no. room size and distance from speakers affect phasing. integration with other speakers is another matter. |

| [#13] 新人 剛買了 subwoofer 怎test? """why set all sepakers to 100Hz is better than 70Hz?""" 1) to led the sub does more work on bass than your small front LCR speakers. 2) your powered sub will provide the energy so the amps for your surround speakers do less work and make clearer sound. |

| [#14] 新人 剛買了 subwoofer 怎test? cpu8088, thanks for your information. 1. i will try set all speakers inc. sub to 100Hz at my pre amp; 2. phase to "0"; 3. vol to 80%; 4. power to "auto"; 5. main power sw. to "all time on" any comment |

| [#15] 新人 剛買了 subwoofer 怎test? dont need to turn 80% ,vol half should be fine , use your channel level to control it . phase was use to set your sub at the same timing with front .(its a little hard to set now ) is mc4 decode or bluray player decode?are u playing dts core or hd audio? if using sound meter set 75 can have good result , then i guess everyone can be expert. hahaha 最後修改時間: 2013-05-20 20:30:19 |

| [#16] 新人 剛買了 subwoofer 怎test? """if using sound meter set 75 can have good result , then i guess everyone can be expert. hahaha""" 75db sound level at sitting position is a standard to facilitate calibration. it has nothing to do with sound quality. the main aim is to have all channels output to your ears at same level otherwise you may have louder sound from left, right, center or inflated bass etc which is not intended. |

| [#17] 新人 剛買了 subwoofer 怎test? seems the sub is very insensitive to set vol at 80% mine is set at about 10 o'clock about 35% and my pre level adjust for sub at -7db. other speakers are at + or - 3db |
