| [#1] 找低音喇叭的phase 有沒有師兄可以解釋以下文字去找到低音喇叭的正確phase ? Method B (more accurate, and more work...) Invert the polarity of the MAIN speaker the sub is CLOSEST TO. Disconnect all the other speakers in the room. Place your head equidistant between the sub and the speaker it is closest to. Play the 80 Hz tone. Adjust the phase control until you hear a distinct NULL. (IT MIGHT EVEN DISAPPEAR COMPLETELY) If you can't get a null then flip the POLARITY switch on the JL sub and adjust the phase control again. There should be some setting of the two controls on the JL sub which will provide a rather sharp null - in fact you might be amazed at how easily and completely the bass cancels. Now put the wiring back the correct way to that one speaker. Reconnect the other speaker and you're done. |

| [#2] 找低音喇叭的phase 首先只接前置喇叭並將它反相接駁(即紅黑反轉) 你個頭就起前置喇叭同subwoofer中間 , 跟住重播一段80hz 然後慢慢調較subwoofer既相位掣 , 直至覺得低音最小或甚至冇 然後將前置喇叭接番正相 , 再接番其他中置 , 後置就攪掂 原理係盡量減少因相位偏差而抵消低音 最後修改時間: 2013-11-12 17:57:09 |

| [#4] 找低音喇叭的phase I use exactly this method to tune the phase between bass and main speaker. But I think it may be more accurate if you can adjust (or with a friend) from your listening position. You can also achieve this by yourself if you put your iphone/ipad at your listening seat, downloaded a RTA/SPL apps and turn the phase knob while watching the screen on the ipad apps for the minimum "db" level. |
