I think you’re making a mistake going with only one sub with your budget as two subs yields much better bass integration and performance. For $1500 you can get two SVS SB2000 Pros that go down to 19Hz and include integration electronics, or you can cheap out and get a pair of SB1000s for $950 that’ll still get you down to 24Hz. Even if you start with one, if I was you I’d eventually get a second. BTW, SVS offers an extremely generous risk-free trial period that includes shipping, so if two subs aren’t a significant improvement you can always just return one. Anyway, that’s what I’d do FWIW. Best of luck.
Subwoofer Recommendations
I am looking for a single subwoofer that will compliment my JBL L100 Classic speakers. This is my office system and I only want 1 subwoofer (no swarm) to add a little oomph below 50hz. I will be using it with my McIntosh MA6600 on the second set of variable line outs. The sub has to accept line in, have a phase control, level control and adjustable crossover so I can cross it over under 80hz or so. I will be still running my JBL speakers full range. Price is up to $1500.00 new or used although keeping it at around a grand would be great. This is the only way I will hook up the sub and I would like something that does go deep. I know there are probably hundreds of subwoofer threads but I have never looked at them. This is just something I came up with today so any help would be appreciated.
