Ok so i am inheriting a paradigm pw2200 sub.....i was looking at buying a new sub like the HSU VTF models, but a free sub is hard to turn down.......so i have a large basement room with an open floor plan and bar, etc so my listening room isnt accoustically friendly. Since im getting a free pw2200 i figured i would go with 2 subs to even out the bass in the room.....i know the pw2200 is an older sub any ideas on another sub i can pair with it or what i should look for??? Do i need to find another pw2200 to pair it up with?
