I'm finally investing in my system after years of running a popular brand (Bose). And all I can say is that this this SUB is amazing. It's a great compliment to my KEF LS50's. Music and movies sound fantastic and just can't say enough about how pleased I am with the SB-3000.
Realistic bass with fast response; Movies hit you in the chest; plenty powerful even in a fairly large room; The app is a great plus
none that I can think of
