Duke is spot on - the more independent bass sources, the smoother the in-room response. As much as I would love to explore this option, until I have a dedicated listening room, it’s just not going to happen. My only option was a single sub, and I went through a few - Velodyne, Vandersteen, SVS, JL Audio, and Seaton. The best option - in my room, to my ears - is my Seaton Submersive (by a wide margin). I’ve never owned, or heard for that matter, a sub that is as powerful, detailed and musical as the submersive.
Should I get a second sub or a higher quality single sub?
I have 600W mono-block amps and excellent speakers. I recently purchased a JL Audio e112 sub. The e112 blends seamlessly with the speakers giving a nice big tone and not too much bottom. Actually, I never really "hear" the sub, it just seems to extend the speakers lower frequency range. The only problem is that when playing the system at moderately loud levels the volume of the e112 must be turned up to the max. I know the sub is operating properly because I returned it to the dealer to be checked out, so I am not sure exactly why that happens.
So, I have been considering whether I should purchase a second e112 sub, or sell it and upgrade to a JL Audio Fathom 112 (the Fathom series of subs is better than the e series). Does anyone have any advice whether I should get a second sub (an e112) or get a better, more expensive single sub (the Fathom 112)? My listening room is 25' long X 12.5' wide X 7' high.
