A pair of SVS SB-3000s would be my choice, sweet spot in their lineup, small enough to not dominate visually, and go very deep and loud, the icing on the cake is the remote adjustability via the app, priceless!
Musical subwoofer under $2000
I’m looking for advice on what vendors to look at as l’d really like to add a subwoofer to my 2 channel setup. The room is c. 30x15 feet or 42 square meters with low ceiling of about 7.5 feet or 2.2 meters. Budget is c.$2,000 and my 2 channel speakers are Sonus Faber Sonetto VIII. My amp offers pre-out connection. I’d like REL but their S range is now too expensive, so something close in musicality would be great.
