Room acoustics

BrianVG · 05:38 PM

Hi all,

I'm using a Yamaha HTT 6230 reciever with JBL E80's.

The photo shows my right speaker, but the two speakers are in the same position, they are surrounded by a wall and a closet. When I play my music/movies at a moderate level everything is fine, but when I turn it up it starts to get boomy. I was thinking to buy acoustic foam to place around the speakers(only helps for high and mids?) and some carpet in front of the speakers.

Does someone have any ideas that could improve the acoustics?

Dont use the tone controls, dont increase bass, if your receiver have direct input switch use it, also buy a carpet, speakers should be far from rear walls. I cant open the picture you attached, but my suggestions in general should improve the bass.

Yes they should, but it's impossible to achieve that. Space is limited.

I'll fix the photo.

I'm thinking to buy this kind of carpet

Does the speaker have a port at the back? If so, I suggest that unless you can move the speaker away from the wall, the port should, at least partially, be bunged up with a bit of foam to avoid boominess...

(Or that's what I've always understood)

Oops, just looked at the manual for your speaker, and the port is at the front. Ignore me...

Even the port is on the front side of speakers the bass will be boomy if you have the speakers close to rear and sides walls. I would close it.

Also try different speaker cables they should be short as possible.

Now i can see the photo, that closets ruins all

Speaker cable is DIY 1,5mm²: 1,60m long , twisted and shielded. I'm not going to change that because I don't believe that any exotic/expensive cable can improve sound.
So the closet ruins all? I was thinking the same. That's why I want to place some acoustic foam against it

Question: is it worth it?
