Let me try to clarify my earlier comments without seeming argumentative. As I understand it, Nearfield Acoustics makes 3 different "models" of the Pipedreams: (1) the smallest has mid-treble line array towers that about 5' (?) tall and a single bass module (with dual 18" drivers, so a very large bass module, indeed); the mid-size model has line array towers that are 6'6" tall and two bass modules; and the largest model has 8' line array towers and four bass modules. So there is no doubt that to house the largest of the Pipedream models demands a pretty doggone large room, if for no other reason than to cope with the 4 huge subwoofer modules. On the other hand, the smallest model, such as the one I listened to at Nicholson's in Nashville, really doesn't need that much space, as long as you can use all of it to make a proper set up, i.e., the room is "dedicated" first and foremost to providing a good listening environment. I doubt that the listening room at Nicholson's was more than 14' wide, the ceilings might have been taller than normal (10-12', I don't remember), but I that wasn't critical, and the length was considerable, maybe 28', but only half the room was being used. My understanding of the theory of music reproduction through the Pipedreams is that the speakers should be brought out into the room and the listening position should be close to the speakers so that you hear direct radiation from the speakers almost exclusively (as opposed to the good mix of direct and reflected sound that you get in most settings with most other speakers). That being said, the bigger the room the better, since size of the room alone will diminish the amount of relected sound reaching the listener. Nevertheless, with the smaller Pipedreams, I think it is quite possible to get most of the marvelous Pipedream experience in a relatively small room, say 12' x 15' x 8', again as you can use all of it. And what is that experience? Incredible holographic imaging and a wonderfully smooth, unstrained musical presentation at the loudest and softest listening levels. A real treat - even from the small ones. I'd get 'em, but I don't have "the room".
