Hi James,
I know this thread is about the Model T; however, it has drawn my attention to Axiom lodspekaers, specifically the M80. Recognizing those are passive and would not provide results that you are seeking with your acctive design, but given that the engineers, techniques, testing are Axiom based, I would be interested in your trained ear perspectives on the M80 with Bryston amplification? I assume you have tried them and if so, how would you describe/characterize them?
