In case it isn't clear in the way i phrased things-- i have 16" of width (between the studs), essentially unlimited height (height of the wall), but only 3.5-4" of depth (thickness of the wall).

i have seen quite a few full range examples (although i'm unsure about bass response) that meet the geometric requirements (ie. Mileva)

Default 8" two-way?

Several years ago, I did a pair of in-wall speakers, essentially a Kef "coda". 8" woofer and 3/4" dome. Similar parts should be pretty available, and we used that system for years for TV in our bedroom. Plenty of headroom and decent sound.

Something like:

Dayton Audio UA711 Speaker Kit w/o Cabinet 302-853

John, if you go in-wall you must choose a design without baffle step and/or baffle diffraction factored into the xo. That means anything designed to go in a box is out.

The Zaph designs suggested by sreten fit the bill well. You can do L and R in-wall's plus an accompanying CC box designed to match. If you're going without a sub, why limit yourself to 80 - 100Hz? Go as deep as you can. Or add an in-wall sub as well - if they'll be covered with grill cloth, none of the drivers are going to be seen.

Personally however I wouldn't choose to cut up my walls, take off the baseboards to run cable etc unless it was the absolute last resort, especially when this isn't even your main viewing area.

Some things to consider if you haven't done so already:
What are your listening objectives here?
How loud do they need to go?
What's your budget?
Are you limiting yourself to a proven design?
Is this an AV application only or also for music?

Can you not perhaps compromise with the boss and go with a couple of small L and R speakers on the wall unit's shelves? If the TV is small enough and you're not too critical for this application, don't even bother with the CC. Or not....

If the shelves are out of the question for L and R (but not the CC?) take a look at this thread, http://www.diyaudio.com/forums/full-...w-you-can.html for something completely out of the box.

See those bird prints you have framed in the corner of the room? How would something similar mounted on each side of your wall unit go down? And without a sub, the added LF of these cornu spirals might be just what you're looking for.

An 8' stud filled with fiberglass has an effective interior volume of like 3.3 cubic feet.

But forget all that in-wall, sounds like your wife will hate it.

Just build some L/Rs that will fit onto the shelves adjacent to the middle of the TV. There is enough volume there for decent bass. Forget the center with such narrow spacing.*

You could maybe fit a decent sub onto the bottom shelf-or two! Ideally, you would make them look EXACTLY like the drawers on either side (or redo those drawers to match!). Again, there is a fair amount of cubic footage on each shelf to make like a rear-facing manifold/slot-load where the woofers face each other to cancel vibration (or one faces the other's back, wired out-of-phase).

It will look really really slick and your wife will be super happy.

Now...to power those subs, too bad receivers generally won't let you wire extra channels lowpassed...but you can get a variety of power amps from eBay or even Guitar Center that will work, probably cheaper than a Class D plate amp from Parts Express.

If you're not happy about the somewhat narrow image compared to in-walls, let me say:
- Eh, a few years, she'll want to change everything anyway, don't do anything permanent to the walls.
- Put some drivers on the side a la Bose or Definitive.
- But hey, you said you had a theater, this is NOT the ultimate experience, you're just looking for better sound.

*Unless you put the L/Rs on the shelves towards the top of the TV, drop the TV down off it's stand, and hang a matching center above the TV, same height as the L/Rs. Then you'd have a monolithic grille appearance across, nice and neat.

Or perhaps build a sub as a piece of furniture. Or a flat and shallow sub that will fit underneath a piece of furniture. Something like the Boogieman on this page for example Home Subwoofer Projects Created By Parts Express Customers, Home Theater Subwoofer Designs, Material Selection, Enclosure Assembly, Home Audio/Video Subwoofer Projects, DIY Home Theater

Still have to deal with the wires of course.

Point being, options remain before you have to start cutting up your walls.
