how to include the subwoofer?

I have power amps (Kharma MP150s) that only have balanced inputs.

I have a preamp (Nagra PL-L) that only has selectable outputs (balanced or single ended), and only one set of balanced outputs. It does have a pair of unblanced.

I have speakers (Wilson Benesch Curve) that go down to about 35 Hz.

I have a subwoofer (Velodyne DD12) that I would like to use to round out the bottom octave and help with some room nodes.

What is the best compromise:

> to use the pair of unbalanced outputs on the preamp and use RCA-->XLR adapters at the amp end, and regular RCA cables to the subwoofer;

> to use XLR y-cables out of the preamp balanced outputs

> use an electronic crossover that has both balanced inputs and both balanced and unbalanced inputs (expensive solution, but offers added capability of not running the speakers full range).

None of these seem very good to me. Any other thoughts? As always your insights are most apprecited

Good point. It never occurred to me to try this. That's probably because, IME with measuring system response in room, I've found that almost any speaker with extended bass response will produce significant excess energy somewhere above 80 hz - in most rooms. Taming this can't be done with DRC in your proposed set-up. You could use bassbusters or maybe you don't need to if your room/speaker system is different than any I've measured - which seems to be the case here.

BTW,

I'm pretty sure that the NHT X-2 is available direct (oand IIRC from AudioAdvisor.com for a few bucks less) with a money back guarantee for a home trial period. There's little at risk if you're tempted to check it out.

XLR Y-splitter out of the preamp.

Run the speakers full-range, they sound great right?

Tuck the sub underneath, less is more.

Clean and simple solution, takes advantage of what you already have.

Dgaylin,

FYI - someone has just listed a used Museatex active/passive switchable high pass filter for sale at $275. I haven't heard this model first hand, but I knew a guy some years back (generally reliable) who swore by it. Just FYI.

David, Marty, thanks for the additional replies. Your two posts bracket my thinking. So....I'm gonna try both and see which works better. Hey, it's a hobby afterall.
