Adding these compression horns to the Tektons ( not shown yet ) completes this 3 way b-amped secondary system. The same speakers pictured here are on the opposite side of the book case. The silver JVC class D drives the i-frame OB bass Alphas ( I usually open both doors when they're playing ). The main amp is the Dared MP-2a3c which drives the white cone Tekton single driver full rangers and the horn tweets. The black unit on the left is an Integra DVD player while the black player above the Dared tube amp is a Sony SACD changer. An old Marantz Model 1150 integrated sits atop a Sony tuner and drives outdoor Axioms on the porch and BoFu full rangers in the LR.
