I didn't read whe whole thread but I also can not speak highly enough about Rythmik subs as an audiophile sub for music. They integrate with my Bryston SST2/ PMC 22 system perfectly. I use dual subs and they are both physically and tonally hidden. It just sounds like I have one speaker and that's exactly the way I like it. Others may provide more power for home theater use but if high quality music is your thing, Rythimic is an excellent sub. Of course they can shake the furniture for movie use as well but music is where they shine.
