Update on my sub search.
I managed to find a way to fit in a bigger sub, plus my budget was getting up there. Anyway, I decided on the PB10-NSD. It saves me $250 over the SB-12Plus. Since I listen to 80% movies, I think it will suit me better anyway. Also, it is a bit more future proof if I move and end up with a bigger HT room than my current 12x12 family room.
It should arrive just after Labor Day
