Rel R-328 Active Subwoofer
Rel R-328 Active Subwoofer upgrades the performance of the R-218 through the use of both an active main drive unit and passive radiator. The main active driver is our much more potent Heavy 10™ -- a driver capable of handling sixty percent greater power and offering superior dynamics and speed. Added to this is a new lightweight, stiff carbon fibre 12" ABR passive radiator that is pitched quite low and thereby avoids the normal slow, plumy quality of typical ABR design. The additional driven surface area that predominantly comes into play at very low frequencies and high amplitudes has the effect of creating a variable cone surface capable of acting like a fast 10" driver for smaller more delicate material, then transforming into the equivalent of a 15" driver when demand calls for it. Internally, REL refers to this progressive driver size as VariCone™. Finally, due to the improved driver, amplifier power is upgraded to 350W.
A special proprietary REL High-Level Input cable is provided with each Rel R-328 Active Subwoofer and is the preferred method of connecting the Rel R-328 Active Subwoofer to your main speakers. This cable joins the Rel R-328 Active Subwoofer to your system by connecting to the left and right channel speaker terminals of your amplifier or surround-sound receiver. This allows the Rel R-328 Active Subwoofer 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.
In order to take full advantage of the Low Frequency Effects channel (LFE), a channel intended for low-frequency content in film soundtracks, provided with the Rel R-328 Active Subwoofer is 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 from the Rel R-328 Active Subwoofer, your system will sound more realistic, musical and alive through improved dynamics, range and scale of the music or film score.
