I can think of two possibilities:

1) Use something, which can be a large medium-thick board (or furniture), on the side which has the speaker closer to the wall. Turn the board at certain angles so that the sound reflected to other directions but NOT to the listening area.

2) Use again something, which can be a large rigid board, on the side with speakers placed at the more open corrider side. This made both speakers have similar reflective area. This create more equal reflection situation for both speakers.

I prefer 1) since it can avoid the first relection point :) I use a bookcase on the side with the speaker closer to the wall to deflect the first reflection point. Not ideal, but better than not using it.

你可在右邊牆貼上一件給音棉防止反射

音棉 also works :)

The only thing I worry is if you buy cheaper 音棉, you dunno what frequency it absorbs most or less. My reading led me think most do not absorb frequencies equally. There exist some 音棉 which is rather equal at absorbing frequencies (mostly above mid ones only). They're however very expensive.

I tend to think use wood board / furniture with rigid surface at cerain angles to block / deflect the first reflection point seem to be a cheaper and domestic solution. Since RIGID surfaces are much less selective at reflecting back frequencies and playing around the angles of reflection could help reflecting most frequenices non-selectively to non-listenign area. Please correct me if I am wrong :)

多謝各位回覆,都系有唔明,聲音編左,點解要在右邊吸音/放吸音綿,另可否用擺位方法解決?

因為右邊末能廷遲反射,所以放吸音棉係正確的

喇叭擺位,左邊有走廊,右邊有牆(約離1呎),

聲音有些編左,

Strange.

ASSUMING no other problems exist (such as your amp or speakers) ...

You may have highly and large reflective surfaces at the left or left end.

But you have a very diffusive or absorptive area on the right.

Then the distance factor may be less important.

Maybe would you tell us or post the environment about

(1) what you put on the right and left side (the entire wall)

(2) how far is the speaker from the 'corridor side'?

之前用大牛龜電視冇問題,換左lcd後發現人聲定位側左一面,整左一輪先知道,部lcd安裝問題,反射面另到聽感有偏差,用塊毛毛一天都光哂,睇睇是否這情況。

........................................

quite strange phenomena.....
seems not environmental problem....

pls reverse left and right channel from amp to speaker to see if it is output problem...

There is always tradeoff for absorbing sound....
should aviod....

racewong兄,

想了解一下放了一大件綠色傢俬在兩個喇叭中間是否有什麼玄機?

Noted that zbigniew821 often thanks others for sharing, and not his threads though. Very nice of you.

Oh, very nice.
I've placed all the sound equipments between the two speakers. Interested to know if there would be any difference in sound after removing it.

有朋友既聆聽環境都係–邊有牆,一邊係走廊,心理上覺得兩邊不平衡.索性兩邊都拉上厚窗簾布.
