Subwoofer Set up Question

I am thinking of hooking up a Velodyne HGS-12 into my system to give my room a bit of a bass boost (Coincident Super Eclipse 3's). I do not want to use the internal crossover in the subwoofer and am thinking of running the speakers full range for my application, two channel listening. My preamp has 2 outputs so feeding the sub is no problem. Any thoughts?

Thanks very much for any input!

No sweat, CK. It's a good method of going and bypasses running the signal to the main speakers through the crossover circuit. I think it's the best way to go for that reason, but does require some careful setup. An SPL meter or better yet, a computer with a mike and software to plot a response graph can be very helpful.

Jax2,

What frequency do you have the sub set for?

For a system without a 2 output preamp, is the only way to hook up a sub by plugging the preamp outputs into the sub via long RCA interconnects, then connect speaker wires from the sub outs to the main speakers? Does the signal coming out from the sub to the mains get processed by the sub's amp as well? If so, this does not sound like a good approach. Is there any other way to do a sub in a 2 channel system without molesting the main speaker's signal with the sub amp? Hope someone can help, thanks.

Since my sub and room are entirely different from yours I don't think it will matter, but mine has ended up at around 40hz (corrected when I checked) so there is definitely some crossover frequency.

Bob - No; you can get a Y-adapter for your preamp which will yield an extra set of outputs if you want to try running your setup differently. As you have it set up the signal goes through the crossover circuit in the sub and is fed back to the amp with the frequency limited at whatever the Xover is set at. Yes, this does put the signal through a path that has the potential to degrade it...or "molest" it as you put it.
