Hi everyone - Happy Holidays

Haven't been on AVS in ages; seems like things are getting better and better.

I'm attempting to run a small/ budget 2 channel setup in my bedroom for occasional use. I'm re-purposing a "vintage" set of Definitive Technology Gems for this task. Being small bookshelf speakers, of course they are missing a bit of bottom-end.

My setup is as follows:

"Vintage" Def Tech Gems (on stands)
Apple TV2 (soon to be replaced by a Nettop/ HTPC)
Emotiva XDA-1 - DAC
Emotiva UPA-2 200 Watt Amplifier

I'm not a huge "bass-head" and my music taste run the gamut. Would a Supercube give me the bottom end I need without being too overwhelming? Maybe something from the ProSeries? I've been scouring E-bay and Amazon for deals around the $350 mark

Another potentially silly question, but would staying with the same speaker manufacturer (Def Tech) offer any real benefit?

Thanks everyone for your assistance... as I'm stuck!

No need to stick with DefTech.

What you should make sure is that you get a sub with dual RCA in-and-out and that has a high-pass filter on the OUTs. That way you can run cables from the DAC/pre to the sub and then from the HPF-outs on the sub to the amp and have proper bass management.

Thanks! Yes, the XDA-1 is connected to the UPA-2 with XLR to RCA cables. This leaves the other unused RCA connectors on the XDA-1 available to connect to a powered subwoofer.

You don't want to do that - that way you are sending full range to the amp.

Just connect the DAC to the sub, and then the sub to the amp - that way you get proper bass management (using the HPF in the sub).

The alternative would be to do as you suggest, but add a high-pass filer to the end of the XLR-to-RCA cables. If you go this route, look into Harrison Labs FMODs

Thanks Rick, would a Polk PSW10 do the trick?

http://www.amazon.com/Polk-Audio-10-Inch-Monitor-Subwoofer/dp/B0002KVQBA/ref=lh_ni_t

Obviously the price is right, but would it offer the tight, smooth bass that would best suited for music?

I wouldn't get the PSW10. It's just not worth it. I would check out the budget subwoofers thread in the subwoofers forum for better options.

Also, consider used:

- from craigslist LA:

Velodyne DLS-4000R for $325

Velodyne SPL-1000 for $400

- from Audiogon

Velodyne Impact 10 new for $230 plus ship from CO

PSB Subsonic 5i for $150 plus ship from NY

NHT Model 10 for $110 pickup in Roseville

Just some ideas.

Might find a demo at a local store.

Thanks everyone.. now for argument sake, would it be possible to stay in my same budget ($350), purchase a nice set of full range speakers and achieve the same fullness I desire? This would not involve the Def Tech gems or a subwoofer....
