Default Triangular ceiling corner baffle

Hi,
We want high quality background music in our small (12ft x 18ft x 8ft) workspace. All the horizontal surfaces are full; the walls are used for work or storage; floor space is unavailable. So I was thinking of mounting a full range driver in a triangular baffle where the ceiling and corner meet. Mono is ok; we move around in the space so stereo imaging isn't a goal and there is only one usable corner. What are the pros and cons of this set up? Might it help the low end? Would sealed box (pyramid) be best?
Thanks, Chris

You'll need a small driver to get good dissipation of all frequencies, 3 or smaller.
You can probably do some BR or aperiodic stuff by cutting small snippets of the corners. You'll just have to do the math and experiment. You'll probably need a bit of stuffing, but otherwise a tetrahedron with three of the walls of masonry is pretty much a dream small-enclosure.

My guess is that cutting the relatively steep angles for the triangle and finding a way to fasten it into the corner (if you are not using silicone that is) is probably going to be your biggest challenges.

Thanks. I'm prepared to do much experimenting with relatively expendable materials. I've been thinking about this for too long; it's time to begin.
