Subwoofer and Von Schweikert 4 series

It depends on what you're using the speakers for, I guess. I'm using a pair of the VR-4 SEs in a two-channel "home theater" setup, and with that rig I'm using two of VSA's VR-S/1 subs. It's overkill, but it really makes a nice difference in the impact department. In my main rig, I'm using a pair of the Jrs. (on loan), and I haven't even thought about a subwoofer--they put out some serious bass.

Ditto, for listening to music, it's waaaaaay overkill.

(My plumber was over - I had my VR4/5s on, and he asked me where the subwoofer was - honestly.)

Best of luck,
