Thin surround speakers...

WilliamRoberts · 3rd March 2010, 08:35 AM

I have been out of the DIY speaker loop for some time, but we recently moved into a new house, and had the downstairs unfinished. I just finished running all in wall speaker wires to the media closet, but now the issue of surround speakers has come up.

I am on the side of diy speakers with quality drivers. However there has been some, well, debate, that let's just do some little 3"x4" satellite speakers for the surround. (I shudder to admit Bose was brought up in the conversation)

When I try to express my desire for real drivers, I get, that the room is narrow, it is for entertaining, and having speakers hanging 9" off the wall would be obtrusive.

So I got to thinking volume is volume, and we are talking about surround speakers, would there be significant issues if, say I took a nice design that called for 1/4ft^3 volume at 8"x10.5"x9" (h/w/d) outside dimensions, and switched it to more like 10"x16"x5" ?? As long as the inside volume was the same? There would still be plenty of room behind the woofer, and it is a sealed box. I know there is the whole golden ration to speaker boxes, I'm just trying to think of a way I can make a more thin box, I might win the war and be able to use some good drivers...

Or if anyone has any advice on thinnish surrounds, would be great...

How about in-wall speakers? You could DIY them or buy them from any one of many different speaker companies.

Thanks for the replies... PeteMcK: The 'Portrait' would have the absolute best spousal appeal, though I am a little hesitant of a woofer that shallow. But this is going to be a dual powered sub system, one front and rear so I'm not to concerned about the bass.

Holdent: We have two walls that are exterior, so no inwalls there... I should have mentioned that.

Planet10: Some nice designs, I hadn't thought about trimming the corners, so visually the box doesn't look as obtrusive.

Thanks again..

The visual effect of the bevels on the corner is a side effect, the purpose is to reduce diffraction.
