RBH Sound SIGNATURE REFERENCE SERIES SV-1212NR Passive Subwoofer

Up for sale is the single most impressive speaker of any size I have seen. 
It is 109lbs using two 12" Reference Aluminum Subwoofers in a piano black enclosure. MSRP was $3,237.95 and honestly that's a reasonable price. Absolutely incredible build quality down to the grill connectors. 
Provides ABSURD bass response down into the teens. 
I've used it in both home theater and 2-channel listening with multiple speakers, it's performance is superlative. I used a Crown XLS1502 1500W bridged amp to drive it, and Audysey XT32 for EQ-ing. I'm sure if you used the official RBH subwoofer amp, or any decent subwoofer amp you would have even better performance.    
I have driven this to eye-watering SPLs and never so much as a little bit of port chuffing or other performance issues. It is rated for up to 2400W! In excellent condition both cosmetically and functionally. 
This subwoofer is bottom part of the $11,000 RBH reference series speakers reviewed here:

The original shipping box and cushioning is included, and I would consider shipping for a motivated buyer, but it would be quite expensive and I would require full insurance.   
Comes with original packing slip dated March 2016.
