No, lol, I meant sub sonic....below human hearing...I don't know what music you listen to that produces 20-30 Hz 99% of the time. Sorry you feel that way...98% of what I like is played just fine...and this thumper, as you say, plays bass guitar, and double bass drums with ease...So, is it worth it to spend the big bucks...NO, is there ANY difference from, say SVS and so on, for what I listen to...NO...I'm not trying to have a HT studio...lol...and I don't go by just gimmick stats...I need to listen first.
As I have come to grips that my teaching salary won't get me hi-end items...I realize that having audiophile Bass is only to show off...not just enjoy...
