The R-218 employs a single down-firing 10" driver in a rigidly braced, high-gloss lacquered MDF cabinet, driven by a state-of-the-art digital amplifier. This combination produces remarkably powerful, fast and rhythmic bass while being extremely energy efficient. REL engineers chose a down-firing orientation as it allows for a simple and harmonious package or a very "quiet" visual design that is understated and elegant. Additionally, the down-firing design is classic REL design approach as for what it may lack sonically in projection of bass into the listening area and leading edge attack, it gives back much in terms of rich, warm room-filling bass.

Serie R Overview

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 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.

REL Connectivity

A special proprietary REL High-Level Input cable is provided with each REL Sub-Bass System and is the preferred method of connecting the REL to your main speakers. This cable joins the REL to your system by connecting to the left and right channel speaker terminals of your amplifier or surround-sound receiver. This allows the REL to receive the exact same signal as your main speakers, providing for a seamless integration of low frequencies into your system. This is a very important point and together with REL’s Natural RollOff™ circuitry, ensures far superior system integration of the Sub-Bass System with the main system. The High-Level connection is active whether you use your system in two-channel music or surround-sound mode. This connectivity method offers noticeable sonic improvements over the common RCA low-level interface by not only delivering the missing low frequencies by creating the realization of a “lifelike illuminated acoustic space”, otherwise known as the “REL effect.” Virtually any conventional separate power amplifier, integrated amplifier or receiver can be used with REL Sub-Bass Systems. Even most Class D amplifiers can interface as REL incorporates REL-D™ circuitry providing the appropriate impedance and grounding for digital amplification.

REL Theater Reference™

In order to take full advantage of the Low Frequency Effects channel (LFE), a channel intended for low-frequency content in film soundtracks, REL provided a .1/LFE input. Most multi-channel processors or surround-sound receivers incorporate a special subwoofer output that bypasses any internal crossover circuitry. It is with this output LFE content can be accurately reproduced and controlled independently of the High-Level input signal. Additionally, both High-Level and .1/LFE signals can be used and adjusted simultaneously in a multi-channel system. By supporting both main, centre and surround speakers with bass reinforcement, your system will sound more realistic, musical and alive through improved dynamics, range and scale of the music or film score.
