I really like the π cornerhorn configuration, for lots of reasons. The gain you can expect is 9dB over free-space or 6dB over half-space. The area expansion from the room's corner apex is equivalent to a rectangular straight-walled horn with 70° flare. The corner makes a very large horn, and since the walls are straight, it provides constant directivity for the wavefront. Combine this with matching HF horns and you can generate a very uniform reverberent field. It's a very simple and elegant design, easy to build and great sounding.
