Building your own enclosures


I'm looking into buying new speakers, and I can get great discounts on in-wall speakers. I was wondering if anybody has had experience with building enclosures to make in-wall speakers into a floorstanding form? My main concern is sound quality, but I have a lot of experience in furniture building and am fairly confident in building an MDF cabinet to mount the speakers. The speakers I am looking at are the new Infinity CAS 3.1. Also, suggestions for the cabinet design are welcome!

I recently heard a pair of Brines Acoustics FT1600 Mk II's. These were manufactured speakers that retailed for $900 plus shipping. They are also available as 'flats' (precut cablinet sections ready for gluing) and pre-assembled cabinets or just the plans for far less. They are a single driver design and sound as good as anything I have ever heard. I just ordered the flats. They are also very efficient. Too good not to look into.

I would check out audioasylum.com "high efficiency speaker" forum and diyaudio.com "loudspeaker" section. Browse, post a question, etc.

Also, Madisound.com for speaker kits and Fostex single driver speakers (like Omega speakers). They have plans for many of the Fostex drivers.

Warning diy speakers can be very addicting.
I'm working on a Seas Thor right now. Got mine from zalytron.com (madisound.com carries it too)
A lot of times, in wall speakers are a free air design, meaning they don't like enclosures. You'd be better off starting with a DIY kit of drivers and build the crossover and encloruse yourself.
