Hello Tireguy:
If I purchase the 20.1, I would probably still try the dual subs. The Sunfire Signatures are flat to 16Hz. However the lowest crossover setting would be 30Hz, which is higher than the 25Hz 3dB point of the 20.1. I think the subs could make the 20.1 unbeatable. But this is only speculation at this point. I am also concerned that my dedicated listening room may be too small (25x14.5x8.5). It would be a tremendous help if I were able to audition the 20.1 at home.
