Pair of REL 528 active subwoofers. The R-528 receives a Heavy 12TM active bass-engine coupled to a VariConeTM 12" carbon Fibre ABR passive radiator producing the equivalent of a 16" driver in an even larger cabinet. The power amplifier produces an effortless 500 watts with the aforementioned components means the R-528 is capable of underpinning speakers with quality low-frequency extension that cost ten times its own price. The R-528 is all about speed and detail as reproduced by the Heavy 12TM active driver, which is actually the fastest diver in the series with the best impulse response. Naturally, its capabilities suggest careful pairing, although it is capable of filling even grand salons with powerful, clean, fast and extended deep bass. 3 Separate Rotary Controls for Hi/Low Level, .1/LFE Level, and Crossover Frequency. Dedicated inputs for Hi Level (Speakon), Low Level (RCA and .1 (RCA). Extremely low crossover points that allow "seamless" blending with any loudspeaker. Proprietary REL-DTM digital amplifier input provides the appropriate impedance and grounding environment for most Class D amplifiers. Piano Black Lacquer Finish. Excellent addition to your stereo or home theater system. $1200 each or both for $2200. I will cover PayPal. Buyer pays for shipping. See http://rel.net/product-archive/r-528/
