REL Acoustics R 528 Piano Black

I am the original owner and the subwoofer is in superb condition. It was purchased from an authorized dealer and has been gently used in a smoke-free home. Although the original box is no longer available, I have an identically sized REL subwoofer box so the subwoofer should arrive safe and secure. All accessories and the Neutrik cable are included. I will split shipping and PayPal fee w/ you.

Manufacturer's description follows: 

Serie R-528 is the
flagship model for Serie R. As such, it is capable of driving even large rooms
and large speakers with ease. R-528 combines a heavy die cast frame, air-dried
hand thrown 12” paper cone, 4-layer voice coil and long travel suspension with
a unique REL carbon-carbon superlight passive. This results in the driven
surface area of a 17” driver. Driven by a powerful 500W next-generation Class D
amplifier that is perfectly mated to the high power 12” driver, R-528 is a
powerful, concussive device that plays exceptionally deep with high output. Serie
R-528 is exquisitely crafted, grounded by a thick billet backplane milled from
6mm T6063 aerospace grade aluminium. This backplane doubles as a heatsink,
thereby eliminating an external heatsink resulting in a cleaner, more modern
construct. Naturally a full REL connectivity suite is featured using high
quality gold rca’s, Speak-on High Level Input and separate .1 inputs. R-528
provides independent volume for High level as well as .1 for perfect
flexibility. R-528 features a next generation Class D amp capable of great
speed and high current while keeping power consumption low when not in use. At
550W, and high current delivery R-528’s amplifier is capable of keeping up with
large-scale instruments such as pipe organs and the most demanding of home
theater soundtracks.
