I use a REL Stadium III sub and it integrates very well wth my Sonus Faber Concertos. It is used with a mcIntosh MHT-100 HT receiver with excellent results. As an organ enthusiast and student, the low registers are very inportant to me. The REL reproduces them with ease, yet is quick on sound tracks and transients. I bought it for HT impact, and two channel, and SACD multi-channel listening. I also drive a pair of Totem Mani-2s in a second system--, they do not need a sub.
