[#1] speaker 氣孔    
請問各位師兄,spk前面出氣和後面出氣的分別.
因小弟現用前面出氣的spk而離後長一呎都覺得很boom,
如果改用後面出氣的spk或者密封spk會否好些.
Thankyou.

you got to identify the problem before you can solve the problem

which frequencies have peak(s)? 30hz? 60hz? 70hz? 80hz? 100hz?

後面出氣的spk對後牆o既距離最敏感;
密封spk相對來講對後牆o既距離無o甘敏感.

you can plot frequency response graph using a cd with various frequencies and a spl meter.

more precise you use a laptop with a sound card and microphone and appropriate software to plot the graph.

if you still cannot do it then get a professionally qualified sound engineer to do for you for a fee.

是的,密封的spk會boom小D.
但boom小D都係boom喎!!換了密封的spk唔保證解決booming問題o架.

你試吓問朋友謝條強過你而家用緊既電源線,比部amp用,可能會解決到呢個問題...又唔洗錢,不防一試!!

貼後牆,左右喇叭距離太遠(喇叭分置於左及右牆角位),貼地等都會加大booming.
試遠離牆,另縮窄o剌叭距離,升高喇叭(離地).

向處估不如比上面三個元素可令兄你得到更接近答案.
重有係咪新喇叭?

rondy Hing,

請試將擴音機及cd機分別安置於地,看問題存在否.

no cure as room too small plus no space sitting against back wall

suggest get a pair of smaller speakers and enjoy chamber music.
