Hi. I'm in the process of refreshing my lounge speaker setup, which is used mostly for TV and Movies, plus a little music. I'm currently running Leema Xone floors standers with matching centre and a BK XXLS400 DF. The Leema speakers are being replaced by MA Apex speakers to allow us to free up loads of space in an awkwark layout room of about 10m x 5m. The sub is therefore going to be a lot more active in the new setup with a crossover of around 100Hz, hence am planning to upgrade. I've narrowed down my search to either a SVS SB13 or dual SVS SB2000. The dual setup will fit much better into the room, with one sub at the front between the LR speakers and the other next to the sofa. But will the Ultra give the better sound? Thanks in advance.
