I posted this earlier for another thread but thought it applied here
I would highly advise you to look at Green Mountain Speakers. I have a small room that is acoustically difficult to place speakers in. I have had a number of "box" speakers with mediocre results. After falling for a pair of Maggies when I bought my Monarchy DAC, I spent months researching what to buy. There was no way I could get a decent placement in the room with Maggies. They need to be placed far into the room (4 ft) and away from walls.
So after months of research, I happened to read a bunch of review of Green Mountain Speakers and became convinced that the time/phase coherent sound was worth a shot. I bought a set of used Europa's and feel they have all the good qualities of planar's without the size and placement problems. Since they minimize reflected sound through the design, they are not as finicky about placement.
Anyway, if you want to avoid large panels and still get the sound, try them - there are other time/phase coherent speakers on the market as well - search "Green Mountain" on the forums for more info.
