I have owned the Nautilus 804 and 803 and found that they were both good, but there were better stuff out there for less money. Try the Sonus Faber Concerto Home which goes for $1895 plus the matching $450 stands. It goes down to 45hx, the Electa Amator II which I've owned is rated to 35hz at -3db, and for a mini-monitor its impressive.
