Wilson Sabrinas, electronics and Subs

Nagra and Wilson are very synergistic. 

I think that a property placed single sub between the mains will stun you once set up. It works for me exceptionally well with Salon 2’s , Kharma mini exquisite’s and Wilson Yvette’s. I place the SW near the right speaker and can tune it to seamless performance. I always run the mains full range. I think that multiple subs will create many issues of integration with the main subs. My SW is a B&W upper end sub with excellent room equalization. FWIW

The Wilson/Rel dealer where I bought my main system and who displays Wilson Alexx and full Rel lineup told me even Alexx benefits by having Rel added. Subtle but definitely benefits. So, yes.

In my in home comparative experience REL are not subwoofers. They are self described as a "Sub-Bass-System" because of their early rolling off.

Their speaker (high) level connectivity is just their old school output-less receiver connectivity remarketed by the new owners as amplifier matching BS. The idea is to match the speakers not their amplifier. REL does this by using a list of sub to speaker pairings. WTF?

Speaker matching is best done with detailed equalization and all the signal from a preamplifiers outputs. A REL may add a couple of sluggish Hz to those Sabrina’s but that’s it. Do your homework. Read subwoofer manuals setup instructions (not the positioning) compared to REL’s.

If your Wilson dealer doesn’t have a Wilson subwoofer on hand find a real Wilson dealer who does. You need a sonic baseline not shinny chrome.
