無聊小搞作，結果

Jazzgd1

話說小弟屋企細，喇叭其中一隻放牆角，駐波都係好嚴重，想搞下，初初考慮整D淘寶低音陷阱，但個位完全放唔落，咁好，是旦係淘寶搵下D隔音錦玩下，一舊水買左卷，其實都知呢D錦對低頻冇乜作用，求其試吓

結果都幾似預期，下面兩圖邊個係前，邊個係後都冇所謂了，不過，中高彈聲真係少左嘅，都唔算零作用。

吸低頻可能要呢D先有效...

成隻喇叭咁大 我連細果D低音陷阱都放唔入
係呢，你覺得見圖中audyssey 幫到手嗎？可信嗎？

Audyssey有一定幫助，你可以on/off聽吓就知道，不過後天總不及先天，可惜香港地寸金尺土，有得玩AV已經好好...

可能要放棄搞駐波問題了，由audyssey話事啦，玩得佢，冇得唔信佢了

You can draw me your floor plan , room size , height of ceiling, location of king seat, options of sub-woofer placement. i will try to use the program "RAW" to simulate the optimal position and the facing direction for your sub woofer.

隔音錦 is totally no use for reducing 駐波 of low frequency ( wave lenght of low frequency is too long , over 1m ) , but the wave of your 隔音錦 is only 2 - 3cm in radius and the tiny hole of 錦 is 1mm in radius. Of cause no effect to your 駐波.
And the 低音陷阱 is too big for HK guy.
The most effective way is relocate the sub .
Audyssey can gain down the doubled volume of standing wave (Black wave) as per specific frequency recorded from which across the test mic, but cannot eliminate the physical condition of the  standing wave, at certain range of frequency you also hearing blur boom.
