REL R-328 10" Active Down-Firing / 12" Passive Front-Firing Sub-Bass System

The REL R-328 utlises both an active main drive unit and passive radiator. The main active driver is REL's much more potent Heavy 10 - a driver capable of handling 60% 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.

• 3 Separate Rotary Controls for (1) Hi/Low Level (2) .1/LFE Level (3) Crossover Frequency
• Dedicated inputs for Hi Level (Speakon), Low Level (RCA and .1 (RCA)
• Proprietary REL-D digital amplifier input provides the appropriate impedance and grounding environment for most Class D amplifiers
• Piano Black Lacquer Finish

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 realisation 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 Theatre 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.

About the REL Serie R

Serie R was conceived as a maximum value proposition in the REL product range possessing many of the performance attributes of their legendary Reference Sub-Bass Systems, yet realised 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.

Instead of the previous model's single active driver in the down-firing configuration, the Serie R features both active front-firing and a down-firing passive radiators. 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.
