My HT setup is in the basement. The walls and ceilng are finished in drywall. Covering the concrete floor is thick padding and thick carpeting. The theatre area is apx 16 x 13, but the theatre boundary on the right side does not have a wall, only a heating duct overhang (about 2'), a couch and two end tables. The actual wall is about 10' further than the imaginary boundary. I may put up a wall, prefab or otherwise at some point, not certain. It was suggested by a tech person at SVS, that I ought to look at the PC Plus series of subwoofers as opposed to the PCi. So the question is, does the composition of my basement floor effect/increase the need for higher wattage? Also, wattage seems to be a proprietary rating. A Rel Q150E delivers incredible subsound with 150 watts. Others rated at 350 or above can't touch it. So how does one know?
