Short version, need recommendations for a subwoofer for use with Klipsch Quintet 5.0 speakers to be used as a PC speaker surround system for games & music.
My beloved Klipsch ProMedia 5.1 PC surround speakers finally bit the dust. It might be repairable, I think it's the transformer (progressively worse humming), but the control pod has been barely functional for years, so time to get something new I think. Except hardly anyone makes high quality PC surround systems anymore. Logitech used to (Z5500 I think) but they discontinued and replaced with something much poorer. So I've been cobbling together a system from parts. I started with Klipsch Quintet 5.0 speakers that were on sale at Newegg for $239 (still are until Monday I think). I searched high and low for a compact AV receiver, but nobody makes one - they are all standard audio/video equipment size - big.. But just by random chance I found a hybrid (tube/SS) barebones 5.1 amp that is small enough to fit on my desk. (Dared DV-6C if anyone's interested.) So now I need a compact reasonably priced sub to accompany the system. I watch no movies on it, it's just video games (hence the surround) and music. So I want something crisp and clean - games do not rely on low frequency effects in the same way that movies do.
So looking for a compact, tight sub in the $200 range that complements the Quintets. Doesn't need a ton of power, it will sit right under my desk. Also should have a speaker-level input, as the 5.1 amp does not have any other outputs (I said it was bare-bones. 5.1 channel analog RCA inputs, 2 channel analog auxiliary RCA inputs, 6 speaker terminal pairs and that's it).
Looks like I missed all the sale pricing of the Klipsch SW-350 as it has been in the process of being discontinued I think - that might have been perfect. (SW-450 is on sale for $199 at newegg, but it's too big. For reference, the old ProMedia sub was 15"Lx11"Wx12"H)
