When I was at Randy's (Sirquack's) house to "help" demo this setup for another guy, he (not Randy) must have said it half a dozen times that he thought that the subs were still on when in fact it was just the M80 fronts. I chalk it up to good acoustical treatment of the room. Randy has taken the time to control first reflections and put in large bass traps which really show in that I was blown away by the performance of the M80 fronts vs. my M60 fronts (in my room that is a terrible acoustic nightmare).
