My room is 20x16 with 2 openings. One small windows into the kitchen, one pretty large into the dining room. I am pairing this up with paradigm speakers, Monitor 7’s/CC-370. The receiver will be a Yamaha 2400(probably). I have listened to the paradigm sub, the pw-2200. It sounded ok but I was curious about what you guys thought would do it in this space. I want to be under $1,000. Maybe the PB2-ISD? Which HSU?
