SabrinaX Sub-Crossover

@upstateaudiophile placement is critical with Wilson speakers. I would recommend setting up and dialing it all without the subs first. Look into acoustic treatments as well. Introducing limited range bass traps and treating the reflection points was a notable improvement in my room with the Sabrinas. After you dial it in, start integrating the subs, if you still think you need them. 

@upstateaudiophile excellent! 

Funny I had too much bass with my Sabrinas when I upgraded from Pass XA30.8  to Pass X260.8 monoblocks and was using Acoustic Zen Absolute Copper XLRs. No sub(s).
Balanced it out by upgrading to Nordost Tyr 2 XLRs. Opened up the top end, cleaned up the mids and tightened up the bass, plus better clarity.
But my room is probably smaller.

@upstateaudiophile yes the Sabrinas are revealing and benefit from top notch cables. I like the Audience AU24SX speaker cables in my system. If you can locate a used set, I wouldn’t hesitate to recommend them. Great value.
