REL T-7 8" Active Down-Firing / 10" Passive Front-Firing Sub-Bass System

The T-7 was developed and designed to bring true REL sub-bass performance to audiophiles on a budget without sacrificing any of the traditional REL Sub-Bass System strengths. You'll find the same cabinetry design and build techniques, quality of parts, unique connectivity and the stunning slam and depth found on even the most costly REL models.

• Custom-designed 8" long-throw active down-firing drive units and 10" front-firing passive radiators (T-7 and T-9 only).
• Powerful 200 watt Class A/B power amplifier.
• 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) each with individual volume control. Speaker level and the LFE input can be used simultaneously.
• Extremely low crossover points that allow seamless "blending" with any loudspeaker.
• Accommodation of Dolby Digital AC3, DTS, MPEG 2 and any other digital sound format that includes a dedicated Low Frequency Effects (LFE) channel.
• Proprietary REL-D digital amplifier input provides the appropriate Impedance and grounding environment for most Class D amplifiers.
• 9 coats of hand-rubbed piano gloss black lacquer or high gloss white.
• Nickel plated steel hardware throughout. Milled aluminum feet.

The REL T-7 sits in the middle of the Serie T range in both price and performance point. Bettering the T-5 by virtue of the addition of a 10" passive radiator and a more powerful 200 - watt power amplifier, it is a more appropriate choice for larger rooms and best mated with larger speakers.

The T-7 is capable of exceptional speed, warmth and slam due to the exceptional strength and bracing incorporated in the enclosure. For example, the bracing is wedged into channels on both the side and top walls enhancing the "energy control" abilities of the cabinet resulting in clearer and deeper bass. Much like the principals that determine the sound of an acoustic musical instrument, the control of resonance and vibration results in a high degree of musical clarity. Even the aluminum feet, due to their high mass and strength, contribute to the enclosure's overall inertness.

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.
 

REL T-7 8" Active Down-Firing / 10" Passive Front-Firing Subwoofer Reviews

What Hi-Fi? Sound and Vision - Feb 2012 - 4/5 Stars
REL's new T-7 subwoofer is an appealing product. It's compact, decently made and not afraid to go loud. Push the volume levels northward and it stays firmly in charge and impressively composed for one so small.

Unlike most of its rival designs, REL has chosen to go the passive radiator route with this design instead of the more commonly seen reflex port. In theory both approaches to bass tuning should yield similar results, yet the passive radiator route allows greater scope for fine-tuning the performance. REL has made it work well in this product.

No matter the source material, the T-7 remains agile and informative, and able to deliver really low notes without fudging the bass frequencies above.

A fine effort, well worth auditioning if you want a compact sub with decent authority. Composed, agile and informative sound; fine build and finish.
