Well to be honest, any of the subs mentioned in my earlier post all perform well with ht. It is true, however, that the PB12-NSD does shine in that realm. It has also undergone improvements in the musical areas as well. Keep in mind, I only ran the VTF3.3 in Max Output mode meaning no ports plugged. Not sure how it would have done in Max Extension mode, but my guess is that is would be very impressive. However, the PB12-NSD just kicks some serious a$$ with ht. My Pluses also do great job. Right now, the Outlaw LFM-1 Plus is still $499 which is an incredible bargain if you ask me. Hope this helps and as always good luck with your decision.
Cheers,
Phil
