REL R-528SE Sub-Bass System
The 528SE was conceived to provide the user with reference-level sub-bass performance, but in a much smaller enclosure and at a lower cost. Embodying many of the performance attributes of our legendary Gibraltar G-1 Sub-Bass System, yet realized to be more compact and affordable, the 528SE delivers extraordinary performance for the space challenged home theater enthusiast or two-channel audiophile.
This fresh design approach offers superiority in all regards over the standard issue R-528, through improved amplification, upgraded cabinet bracing and driver design. R-528SE still features both an active front-firing and a down-firing passive radiator, using the same custom design carbon fiber 12" active drive unit employed in the G-1. The 12" ABR passive radiator is also of a carbon fiber design. All in all the 528SE excels in drive, extension, ease and musicality wherein its speed mixes with greater body and heft to produce an altogether more profound musical event. Each 528SE 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. To further distinguish it from the standard version, the top and side name badges as well as the massive support feet are coated in nickel plated chrome for a sophisticated high-style appearance.
R-528SE represents the top-of-the-line in the Serie R range and is bestowed with superlative depth, scale and slam. Numbers do not tell the full story here, as the weight and power of R-528SE at full output is prodigious indeed. The R-528SE's 12' carbon fiber active bass-engine coupled to a VariCone™ 12" carbon Fibre ABR passive radiator produces the equivalent of a 16" driver in an even larger cabinet. The upgraded digital power amplifier employed produces an effortless 500 watts that means the R-528SE is capable of underpinning speakers with quality low-frequency extension that cost ten times its own price. The R-528SE always exhibits extraordinary speed, detail and bass impulse response.
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.
