Looking at adding a sub for music only in 20 x 16 room...first auditioned pdr 10...not that impressive...then heard the pw 2100 which sounded very good($750 usd)...what about the ps 1000 model?($580 usd) At any rate...with any maker...as you climb up the price point ladder ....things do improve...still might try HSU...and the latest B&W 600 line (all sealed models) was very transparent and musical....any thoughts
