Hello everyone and thanks for any feedback in advance. Ok, heres what I am looking at: First I just bought a new Harman Kardon AVR235 and a set of Infinity Primus250 towers for the front, now I am looking for a sub to go with this gear. In my price range I am looking at two different subs, the Infinity PS12 and the Infinity CSW10, 12" vs. 10"... so My room is approximately 23'x 18', not huge but not extremely small. Looking at the two subs as far as specs go, looks like the CSW10 might be my better choice since it has a little lower frequency response and has more power than the PS12. A little history as to why I am asking for advice, I am replacing a Klipsch KSW10, which was OK, but didn't rumble as much as I would have liked. Musically, it was nice... but when it came to movies it seemed to bottom out alot. So I guess I am just scared that buying another 10" to replace my KSW10 might not be the right thing to do, but with the CSW10 it looks like alot nicer sub??? HELP!!!
