Feel the bass
It looks cool and the controls built into for couch are nice, but for $7K!!! Also, with a 300 watt amp you probably won't feel much.
The following DIY setup would probably provide more performance:
Couch matching existing furniture $1K
Buttkicker LFE $250 x 2
Buttkicker Amp $350
Buttkicker wireless $99
Mounting brackets $100
At 2200 watts, the buttkicker amp will definately deliver more tactile LFE to your couch.
An alternate solution for 2-3K, but two SVS plus subs, or two Axiom EP-600s. You will definately feel the bass.
