拉對喇叭離場由3呎起一路續呎增加到6呎至9呎.

直到聽起來無峰值BOOM聲就差不多.
到時先拉闊對喇叭搞音場

once I walk around 2nd hand hifi shop where C2 was singing, the boom sound got over the whole room only to produce muddy sound. I asked the boss why such unpleasant issue happened, he then switched from Krell 300il to Rowland 725 mono block, all booming was.gone

如果有反射孔,可以海綿或布塞住佢,用幾多?一路聽,一路塞.

EQ係比較實際！
I also suffered by this issue.
因有C竇做實驗 好多方法刀試過
吾喜歡用EQ 只因為it reduces sound clarity
確有此問題 但考慮利遠大於弊
亦係最簡單有效方法 值得使用

貴的EQ 对清晰度影響無咁大
平的EQ 也未常不可
也可向朋友商借一部有高低音控制的前級或integrated amp
便可窺探效果

最直接同有效既方法係用EQ，輕輕一推，搞掂！

^_^

they did not change my cross over as i only give than a pair of bass drive to recoil it. it was bacause one of the drive burnt out.
it is a RAM speaker which i put it away for years. i re-isntall it by doing some cleaning and find that i prefer it rather than my current speaker

i will try the resistor first and see what happen.

thanks ching

Use speaker spike

Yes, you have to find out the root caused of too strong Bass. Then .. 對症下藥.

The guy possibly changed the gauge size of the inductor. There may be no use for you adding a resistor because it only reduces the loudness of your bass driver unit. Which English speaker is it? It may be possible to have a search on the internet and get the crossover circuit for it. Could you take a photo on your crossover and post it here?

thank for all ching advice
as my bass drive was fixed long time ago, i do not think the shop still remember what they did
i believe the guy actually put more round of wire for my voice coil for my bass drive
i guess i will put a resister on the bass drive

do i need to have special resister for it, which type and grade should i use?

please help again

thanks!

unless u know what has been changed and have a measurement made there is no perfect cure.

add a l pad

or as etsang3 suggested move above ground and side walls as it can be -3 to -6db

dont think changing power cables or speaker cables can get that effects.

May try different power cable and using different spikes for your cdplayer.
You have to try and listen

Try 6" above the ground then 12" then 18" etc..

move the speakers away from the wall

Please check if the component of your speaker crossover was changed. If yes, restore the original value will be the solution. You may ask the guy what he did for your speaker.

Simple ask the guy who create the problem fix it.

Why not just try to add 1ohm resistor at the bass driver?

＞＞equalizer

Yes, should be equalizer for it is very handy indeed.

sound trap.
