Was: £349.00

This modern life we inhabit, where less space means more enjoyment in more rooms than ever before. Movies in the bedroom growls, rumbles  and springs to life, the gaming console in a spare room takes on a whole new meaning when the effects are suddenly rendered with lifelike bass, and your favorite digital music files appear and float in front of the listener with lifelike clarity and power. T-Zero makes each experience better, enriching even modest systems with power and natural bass.

This is the premise of T-Zero; bringing the quality and indeed the full REL connectivity suite, long throw drivers and powerful, reliable amplifiers to a new lower price point and dimension. T-Zero is, in many ways, the most difficult design we have ever executed because never before have we delivered so much for so little with so much quality. 5 coats of lacquer, as in all Serie T, next generation Class D amplifiers, High level inputs, .1 separate input stages, rugged 6.5" main driver with exceptional output and low bass extension for its size means T-Zero gives up little to much larger units from the competitors.

Miracle In Miniature

Miracle In Miniature

Industry veterans are in awe that REL are able to bring the full REL input/connectivity package to life at such reasonable cost and retain the beautiful execution of fitment and detail for which we are so well known. High-level with crossover available down to 25 Hz, a dedicated .1 Input so Theatre Reference mode can be engaged; T-Zero is a miracle in miniature.

Classic REL Design

Classic REL Design

At REL every clean sheet design begins by defining and designing the best bass engine for a given application. While the long throw 6.5” is their smallest-to-date, make no mistake that it is powerful and articulate, and able to fill medium-sized rooms effortlessly. Have a much larger space? Distribute them throughout for an unobtrusive spacious presentation of music and film sound.

Industry Leading Build Quality

Industry Leading Build Quality

T-Zero is built using a super stiff cabinet construction that drives the resonant frequency higher so it is more easily damped by our instrument-grade bracing. We utilized 5 full coats of lacquer, and solid aluminium feet and badging because REL owners understand quality must extend throughout a product, not just in the most obvious locations. And its diminutive scale allows it to all-but-hide among the furnishings in your home.

Well Connected

Well Connected

As a pure high-end company, REL believe in first doing no harm with their subs. So, they offer no high pass crossovers that interfere with the bass from the main speakers. REL recommend connecting via a special high-level connection whenever possible because doing so allows the voice of your main system to be built forward into every REL. REL permit crossing over quite low because their designs produce truly deep bass, where many of their competitors focus on very loud middle bass.

Film, Glorious Film

Film, Glorious Film

REL worked closely with one of the leading movie sound studios to create REL’s Shotgun Theater Reference Circuit, wherein the low bass directed to the main speakers is reinforced by the REL all-the-while reproducing the dedicated .1 LFE channel that is the heart of thrill in a movie soundtrack. There's a dedicated single phono input for film’s .1/LFE channel with its own volume control. Crossover is fixed, per Dolby specification, at 120Hz.Simply dial-in the High Level using dynamic music, as usual, then switch over to a film soundtrack and bring up the gain on the dedicated LFE circuit until just below clipping and you’re all set.

Drivers Make The Difference

Drivers Make The Difference

REL carefully design our drivers to reproduce low bass, with resonant frequencies that are exceptionally low, long travel suspensions to allow high output and ideal motor assemblies to energize the system. REL refer to them as bass engines since this descriptive more closely defines their function. Their engines are carefully designed to start and stop quickly, since it is the quiet in between notes that defines the meaning of music.

Why No 1000 Watt Amplifiers?

Why No 1000 Watt Amplifiers?

REL engineers work hard to keep moving mass as low as practical in their drivers, thereby allowing the overall design to be more mechanically efficient. Greater efficiency means obtaining more output from fewer watts of electricity consumed so there's no need for thousands of watts of power to get a high sound pressure level.

Instrument Grade Cabinet Bracing

Instrument Grade Cabinet Bracing

All current REL designs benefit from careful hand fitting of intricate internal bracing. Borrowed from acoustic instrument design, the bracing is vastly different from the normal hard-edged windowpane braces that produce audible and evident noise when driven as hard as REL designs drive the cabinet. As the careful observer can identify, REL have taken great pains not only to locate and quiet significant modes, but each internal surface is carefully radiused to eliminate hard-edged surfaces that produce audible noise and distortion.

Monoblock Amplifiers and High Level Connection Note:

REL do not recommend use of a single REL subwoofer with ANY brand of monoblock amplifier as it is possible to observe slight channel-to-channel dc offset that can result in mild oscillation. For any monoblock, REL recommend use of stereo pairs of the appropriate model of subwoofer.

Easy to set up. Suprising amount of bass for such a little box.

Understated device with truly excellent performance. Easy to connect. Very good documentation. A wothwhile enhancement to any quality speaker system, particularly if using smaller driver units. Finally, excellent service from AudioVisual online.
