Take a look at Rythmik’s F15HP, a lot of bang for the buck. If you want to keep things closer to $1K, the F12SE. While I use 4 subs in my main system, unless you’re planning to really rock out while you’re working or have a huge office, I don’t think you need 2 or 4 subs in an office. If you just want to add in some low level information that your main speakers can’t provide, a single sub can work fine in a smaller room. I have 3 smaller systems, each with a single sub (all are sealed subs) and they all sound great for their purpose.
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.
