In my main system I have large "full range" speakers, specified down to 32 Hz -3dB, and the best improvement I ever made to the system was adding a subwoofer. Go for it. (I use one sub, so can't speak for the relative difference that a second one makes).

Bill B, thanks for the quick reply. Was kind of hoping someone would say it was worth it (not in terms of the bank balance of course...)

How is yours integrated/connected? Do you run the mains full range and then use a low x-over setting (like 40-50Hz) with the sub, or cut the mains off at a particular point and let the sub take care of the relatively low stuff (ie below 80Hz)?

since my (Vincent SA31MK) preamp has two sets of outputs, I run my main speakers full range from the power amp, and use one set of the preamp outputs to drive the subwoofer from its line level inputs.  I don't remember my crossover and phase settings, but I followed the recommendations of the subwoofer's manual in adjustments, and evaluated by ear and decibel meter also.

by using the mains full range, I figure they are running the way were made to run (and I don't feel like i'm "wasting" them by cutting them off with a crossover).  Also, I feel that with woofers from the mains plus from the sub, I am getting benefit of multiple woofer locations, which is kinda similar to the idea of using 2 subwoofers.

Whether you need one or two subwoofers is a question of room volume and how big and powerful each subwoofer is.

You should run the mains full-range and use the low-pass filter of the subwoofer to limit it to operating below 35 Hz or so.

How did the SB-2000 turned out? I just got one for now and it's on the way home on the mail.

Thanks

Welcome! mahont03 -

before buying any subwoofer, demo a REL sub. These are the best on the market, most musical and easiest to integrate into any system (large or small). Even the older models, used, are outstanding!

I'm running a Britannia B2, crossed at about 28Hz with the relatively full-range Dynaudio Sapphires. I'm also using an older Storm III with Martin Logan SL3s (soon to be replaced by Dynaudio Excite X-12s). With proper set up you only need one sub (unless headbanging) and you'll never know where the sound is coming from. You will also get the hall ambiance as well. If you've never auditioned and REL I strongly advise doing so.
