Thanks for the quick feedback.
Something to note. Mike @ acousticsounddesign offered me the PA-150 for $340 shipped (20% off) on the phone.
It was almost too good to pass up, but unfortunately because of the circumstances, I couldn't bring myself to force my family to lug a 100lbs sub back with them across the country.
I bought the PA-120 for $207 shipped. I really hope my room isn't too large for this sub, but I know I won't be disappointed.
I don't want to piss off my neighbours and for the price point, and judging from reviews, I think I will be pleased with the performance.
