One thing I noticed in Dallas, listening to a number of the demo systems, was that some had more bass "slam" than my set up at home. So I'm wondering why. I can tell right away that some of the systems had exagerated bass due to the small room, and that is easy to spot, it sounds bloated and boomy. What I'm looking for is clean tight bass that can thump you. Know what I mean? So give me some advice. If I measure about any equipment setup I can put my hands on, it's reasonably flat in my room from 50 on up. And I'm using high efficency system (min 97 db and up) - I've tried amps ranging from 2w to 8w to 30w. I've tried SS and tube. My conclusion so far is: 1) It isn't the speakers; 2) it isn't the amps. So it must be the room? My listening room is a large basement space that has concrete on the floor, front, and both side walls, normal stud wall on the back, and open joists on the celing. But the hotel rooms, I'm guessing, are about the same - some concrete, some stud walls. No? For speakers I've tried direct radiators, open baffle, and compression drivers (1000 hz up). By the way, I can make the bass boomy in my room, but it isn't a lack of bass, it's a lack of punch. As for driver size, I've used JBL 2226 in a 2.5 box (15" driver) and I've used 15" IB sub on OB. So I also don't think it is related to the size of the radiator I'm using. Should I be looking for a room suck out at some higher frequency? Any ideas?
Thanks!
