I have thought about this also. In big rooms where you are 12 or more feet away, it is hard to get out of the coverage area, but in a small room it is hard not to. Do you want the coverage so you can have a wider listening area, or do you want to put more upper midrange in the front part of the room for reverb? I could probably glean this from Toms post, but I am too busy and tired to dig through posts right now :) The only reason I ask is some of the wide ones have bad top end dispersion, sometimes worse than standard 90 x 40's. If you are going to be in one spot it won't matter much, but if you want extra-wide and even coverage, be careful choosing.

There are a few wide ones, a Beyma and some P-Audio models. I have possibly found every currently available production horn in the Pi size/frequency class, so I can look through my notes and point out a couple of links later this evening.

later,
