The R-528 receives a Heavy 12? active bass-engine coupled to a VariCone? 12″ carbon Fibre ABR passive radiator producing the equivalent of a 16″ driver in an even larger cabinet. The digital power amplifier employed produces an effortless 500 watts with the aforementioned components means the R-528 is capable of underpinning speakers with a 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 12? 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.

Serie R was conceived as a maximum value proposition in the entire REL product range possessing many of the performance attributes of our legendary Reference Sub-Bass Systems, yet realized to be more compact and affordable. This fresh design approach offers superiority in all regards over the previous R-Series through improved amplification, vastly better filter networks and upgraded cabinet and driver designs.

Models R-528 and R-328 feature both active front-firing and a down-firing passive radiator while R-218 employs a single active driver in the down-firing configuration. The range excels in the drive, extension, ease and musicality wherein their speed mixes with the greater body and heft to produce an altogether more profound musical event.

Each Serie R model is available in a stunning hand-rubbed piano black lacquer that will grace your living environment as well as your stereo music or film sound system
