I tried the single driver route. My experience was that I heard some of the benefits and I also heard the problems. They can sound very clear and coherent and,most importantly, involving. I couldn't, however, get over the obvious reduction in bass output and some of the unusual tonal balance problems. Maybe with much more expensive drivers, like Gregm suggests, the strengths would be greater and the problems less obvious. I used $280 Fostex drivers. If you were to buy a subwoofer,add a supertweeter and use filters for the frequency response irregularities, it could be made to work. It's a mixed bag of strengths and problems. Can be made to sound glorious,see the TNT article on the use of Lowther drivers with success.
