Wisdom Audio SCS RTL Powered Subwoofer

This is a slightly used unit rated 9/10 Audiogon (excellent condition) There are no discernable flaws physically or sonically. Provided with original box, packing and documentation. This subwoofer is large but slim and fits behind furniture where it can be heard but not seen. High WAF and great performance!!  I am selling because I am changing over to full range JTR speakers. Original MSRP $4000. Best offers will be considered. I have stock pictures up because this subwoofer will remain in place until packed. I cannot get a picture of it as it's currently behind my sofa.
Also, important note : No DSP is required for this unit!!! Wisdom offers this as an accessory but it is not necessary for operation.

**** Local pickup is preferred but can ship to continental US via FedEx or UPS Ground for $125. You may also provide your own shipping method once purchased and payment has cleared *** 

Description from manufacturer

Powered Free-Standing Regenerative Transmission Line® RTL Subwoofer 
The compact size and aspect ratio of the SCS allows it to be placed in areas where other in-room subwoofers will not fit, offering customers a unique freestanding subwoofer option – one that can actually be hidden. The SCS is powered by a 400-watt internal amplifier and is capable of 120 dB @ 25 Hz. The dual 5-inch x 7.5-inch woofer design yields an equivalent active cone area of 13 inches and is taken directly from the larger S90i in-wall subwoofer.
