I am already a subscriber to both Audioholics newsletter and SVS news letter.
I already have the PB12-NSD and would love to have another subwoofer to balance out the low end in my theatre room. I have read a lot about how two subs adds a level of balance and have dreamed about doing it - however, budgets are what they are and right now, purchasing a new sub is not in the budget. Winning one would be a great gift!
