The gain is adjusted to restrict or add bass to subject material, is what I meant. This 150WW, 10", is still over powering for my 12 X 8 room area. For my bass likeness, it is at 1/4 gain or 9 O'clock, for example. It is enough bass for explosions and the like. lol Ya, some day, I'd like the PSB Alpha S10, but not sure if necessary, as I am a DD movie watcher. Whether this would be any better sounding...who knows? Or any you mentioned. I got this current Klipsch, which lists for $399.00 for $199 on sale, last Spring. Anyway, appreciate you comments. Movies are where I am at, not music. Sorry to steal this thread, but, maybe a $700 10" subwoofer, would sound just as good as a $400, for movies? In general terms.
