師兄，我買了這隻碟回來，可否告知做法如何？
TRACK 8:80 Hz, 2 min @ -1dBfsUsing 80 Hz is an easy way to set the relative phase of the JL Audio subwoofers to match the "mains", especially if you are using 80 Hz as the crossover freq, such as when connecting to a Home Theater receiver. However, whether or not you are using a bass managed HT system, or a separate crossover, this method is still very useful.
Method A (easier, but less accurate)After you have placed the sub where you want it, put YOUR HEAD equidistant between the sub and the speaker it is CLOSEST TO (for example the LEFT FRONT). Disconnect the 'other' front speaker. Play the 80 Hz tone and adjust the PHASE CONTROL of the sub and the POLARITY SWITCH until the bass is loudest and cleanest - in other words, the peak.
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.
我的sub crossover 是100 Hz, 這樣是否用 100 Hz 去set up ?? 本帖最後由 chhanthony 於 2013-11-14 13:47 編輯

100hz crossover
1. 先將一對前置喇叭線的正負對掉
2. 喺AV Processor內設定唔要pure direct
3. 用CD/BD Player播放100hz的test signal 以digital輸出
4. 自己將sub-woofer上的phase由0到270一直來回反覆咁扭
5. 請家人/朋友坐喺皇帝位幫手聽 (又或者佢地扭你聽)
6. 直至聽到出嚟嘅聲音係最細聲(甚至係無聲)時咁就為之in phase
7. 將前置喇叭線正負掉返啱
完成
呢個放法亦可以用嚟幫手set距離
BTW
以Sunny嘅器材應該用80hz甚至更低都卓卓有餘，照計無需要用到100hz。 本帖最後由 sunnyyuen 於 2013-11-12 16:27 編輯

謝謝師兄，原因用80 Hz, 感覺前置聲音不自然！用了100 Hz..感覺舒服一些，你幾時有空到我家指導一下！

或者先用80hz或以下set一次睇下重有無唔自然
set距離都係用以上同樣的方法，只係用AV Processor set距離代替用sub-woofer上的phase去set。
我當然有興趣體驗一下Sunny套老麥前後啦{:1_335:} chhanthony 發表於 2013-11-12 16:19 static/image/common/back.gif

請問係咪只對掉喇叭上的正負，amp不變嗎？ chhanthony 發表於 2013-11-12 16:19 static/image/common/back.gif

請問師兄, 將前置喇叭正負對掉用意係咩?
