I look forward to reading your facts.
BTW, you should hear a difference between your 160v3 mini and the 160v4. I had my 160v4 playing full range so you may want to try that.
As much as I loved the 160, I no longer need a centre with the active LFRs. The centre image is vastly more natural now and I hear details just to the left and right of centre whereas before, these details were collapsed in a more focused region. Unfortunately none of the other Axioms could reproduce this effect during movies.
Did you find out from Andrew what the impedance profile is for the M60HP?
Ask Andrew to send you port plugs. If you place them too close to the wall, you may need them. Maybe ARC can fix that for you though.
