I just purchased the XV30 (base plate model), as Tom had one left that was a trade in for the Triad. So as soon as I receive this beast and calibrate it, I will give a full review. I'm pairing it with a PB12/Plus2 in a 1600 cubic foot theatre! I will calibrate it individually first, and show my in room measurements, then I'll recalibrate both subs. Should have tons of headroom!
