I know, I know, in-wall is not the best, especially if you're not doing major constructive surgery. But at some point, we will change our DLP for a flat TV, and I don't want to continue with the slim Infinity towers I have. They are nice, but low sensitivity. I want to get back to efficient, open-sounding drivers.
I'm open to what type-could be a two-way or maybe a good fullrange driver. I seem to remember Polydax had some 6" that were like 96 dB sensitivity, then I would need tweeters to match. And I know there are some (very expensive?) fullrange drivers which then have no crossover. I'll probably build a sub into the ceiling so the bottom end is not a big concern, it is OK if the bass rolls off kinda high.
On the other hand, drivers need to be 3.5" or with drywall thickness maybe 4" max.
Ideas?

Check out the In the wall back loaded horns thread here:

With a Fostex FE166 you can get 95 dB to 100 dB of bass output with 1 watt. It reaches pretty low down to the 20's Hz.
Another option is a flat, on-the-wall Cornu speaker:

Here is sim of Cornu with a TB W5-1611 at 3 meters away from wall.

I've done a lot of in wall speakers in the past year. I like these two.
This one is very effecient but requires subs. In-wall version of Delta Max
And this one has pretty good extension and fairly effecient, but the mid tweet is NLA and I did it active. Could be done passively though. http://www.diyaudio.com/forums/full-range/225714-wall-fast-really-rocks.html
By the way. There's nothing wrong with in wall. It sounds amazing to me. I'm sure you'll find something that works for you.

Hi, I don't see any reason why not using the Fostex FE166En 6.5". It works fine in a BR 10L with a 2" port (12cm length). You can cross to sub 75-100Hz.
The big brother Fostex FE206En 8" might not have the clearance you need... and is more expensive.
Also nice HE drivers for 2-Ways and full-ranges at faitalpro.

This might serve some inspiration. FE206 in-Wall horn done by one of the guys on the JoeList.

Whether a pair of "in-wall" enclosures that protruded out from the face of the drywall would be a huge aesthetic no-no would depend on the individual situation, but my concern would be the beaming at higher frequencies. Regardless of size, I've found any FR driver I've used so far for the L&R mains have benefited from minor degree of toe-in.
Ryan's approach in the threads referenced above are rather interesting - IINM the one with small tweeter had a small wave-guide, which with minor shimming could probably provide the focused toe-in that could help offset HF beaming.
Ryan - once completed with the fabric covers, how far did these protrude from the wall?

Of who?
You're correct about the sensitivity, but into a wall aren't they all too deep (at least anything that could cover any amount of midrange)?
I'd love a big circular horn. I wonder if it would be TOO weird if there was some bulging into the rear hallway behind that wall...
