I agree with mazersteven. Two PB2000 subs would be a good idea. Now on sale for under 600 dollars US, I think. These models are newly manufactured, they aren't damaged or dented. Caution: this sub is end of the line, SVS has already released the 2000 Pro line of subs. You won't be able to easily get a second one in a year or two. The 2000 Pro line is 799 US. It is getting very good reviews, as did these on-sale 2000s. I have rarely been so happy with an audio purchase in my life; I'm not joking. Bless them all, but every sub-500 dollar name-brand subs I bought over the decades sound like 80s era boom boxes compared to one of these SVS subs. I was gob smacked in how the SVS subs (two!) improved my music collection, not to mention movie soundtracks. Your room seems huge. I hope you consider moving the couch away from the back wall in a room that large — what with SIS* spreading like wildfire in these times. (*SIS: Spousal Irritation Syndrome)
