I have been promised a Vector Research subwoofer that was part of a (two)satellite system, and am curious about its history and performance(save for its previous owner). There is absolutely nothing I can find on the internet, save on some VR receivers. The model number is (I believe)VRP 220. Any knowledge/experience with this sub/system or pointers to resources on the net would be appreciated.

Am also curious about how/if such a sub can be hooked up with my current system, a pair of bi-amped Wharfedale SP-83 Saphires and a NAD 7240 receiver--I've never tried a sub from a particular satellite trio with different speakers-am I asking for trouble?

Thanks all in advance.
