I haven't had the opportunity to hear the PB-2000, but I imagine it's a very good subwoofer. The LV12R is not the Rythmik equivalent to that model though, it would be the LVX12 instead. The LV12R sits in between the PB-1000 and PB-2000. If you can afford the extra few bucks the LV12R is well worth it. If not, the PB-1000 is certainly no slouch.
