I don't have to much to offer here that hasen't been said already. I still have the KSW-100 sub. I haven't heard too many positive comments on the newer KSW-10,12,15 line, but this little sub to pretty darn good. I just upgraded to the SVS 20-39PCi but i'm definitely holding on to the ksw-100 for the bedroom.
