Subwoofer to go with new BW 804 D3


I have had the 804D3 for a few days. I am slowly liking it. I do feel for home theater purposes I need a sub. Should I pair SVS sub ( PB12) or get one from BW for subs?

I'd think that a single Fathom F112 V2 would be more than sufficient. You can always get another down the road. I'm using an 18 year old B&W ASW650 sub and last night thought to myself "awesome bass" (also have 804 d3).
I agree with the recommendation of the JL Audio e110 or e112. I'm using an e110 with my B&W N804s and it packs quite a punch.
