#120 REL Acoustics Carbon Special Black Label: $4,999.00 Estimated ListenUp eBay
Same family: the REL Acoustics S/550 (smaller subwoofer, estimated 3.5/5), the REL Acoustics S/850 (smaller subwoofer, estimated 3.7/5) and the REL Acoustics 212 Black Label (larger subwoofer, ranked higher, estimated 4.2/5).
Pros: A Serie S flagship with an all-carbon fiber 12” active driver and a 12” down-firing passive radiator, driven by a 900W Linear Class D amplifier and reaching 19Hz (-6dB) in-room.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from REL’s measured HT/1510 Predator II (118.1dB in the 40 to 80Hz CEA-2010 bands) and R-528. It weighs 44.5kg.
