thanks Everyone !
I went with the M60, QS8, VP150 combo. Also, ordered the 25-31PC+ from SVS. The axioms have arrived and am in the process of hookup. Hopefully, everything will come together nicely. The supplied T-bracket with the QS8 is not very wide.... My stud detector gizmo manual says that usually studs are 16 or 24 inches apart, but the QS8 T-bracket is only 8 inches wide so I am unsure how I'll install them.. Any ideas ?
