Many don’t realize the intense linkage between performance and design here at REL. Performance is everything to us and so it drives physical design revisions. Our engineers, recognizing the need for greater acoustic volume to achieve the goals of greater fluidity and power, turn to the designer who works dimensions to fool the eye into seeing a smaller, more compact footprint even though cabinet volume increases. Using gently rounded corner radii that allows the eye to flow over and see less visual mass. The result is both modern and familiar with no unnecessary adornment.
T/5x borrows a single longthrow 8” (200mm) bass engine from its elder sibling, T/7x. Developed using a composite of aluminum and light paper, this cone captures details that will amaze, while supplying sufficient energy to plumb deeper than one would expect for its size. In T/5x, its throw–the ability to play louder–has been increased. Internally, the suspension received numerous upgrades akin to transforming the handling of a car from a family sedan to a true sports car. More power, greater finesse.
T/5x builds on its predecessor’s reliable, expensive 125 W Class A/B amplifiers. Internally, key items significant to upgrading transparency and speed have been upgraded at no cost to REL’s legendary reliability. Separate inputs for High Level Inputs, Low Level Input (necessary for the increasing number of powered active speakers emerging on the market) allow for a natural, perfect transition from speaker to subwoofer. And in theater a separate, dedicated .1/LFE Input for Theatre performance permits automatic transition between music in high end 2-channel applications and home theater without needing to change a single setting. Magic? No, superior engineering.
Standby Mode switch is only included on 220V units.

The 8” long throw active and 10” passive drivers are where T/7x derives its incredible speed and clean finish. A thorough revision of critical suspension components are responsible for the agility and suppleness of T/7x. The T/7x sounds louder and more powerful is expected, but few would predict it also is faster, more reactive and transparent than our prior generation, itself a paragon of virtue. Stiffer suspensions better suited to advanced duty mean not only can each driver trace minute details, but also travel farther and handle more power.
We have retained our signature Class A/B amplifiers used in every generation of Serie T since 2006. Reliability is the key to happy ownership and with some 200,000 and counting of this range leading long happy lives, Serie T/x owners can feel certain of REL’s standard setting reliability. The powerful 200-watt mosfet amplifier used in the T/7x remains an icon of sound and reliability with huge reserves of current. Massive power supplies are used and small upgrades are found everywhere. New driver mosfets that open up performance and transparency and new methods for securing the toroidal transformers mean better performance and superior reliability. The best gets better.

To achieve higher output with better control requires a complete overhaul of the suspension components. Much like the suspension on a sports car, these items are responsible for the tuning and feel of our designs. By increasing the cabinet volume, efficiency is improved yielding higher output for no more amplifier power. Less back pressure inside the cabinet means we can tune for a stiffer, better controlled driver suspension. We retained the best aspects of our previous design, such as the aluminum center cap responsible for stiffening the lightweight 10” (250mm) cone while adding almost no mass. The updated combination produces considerably better attack and dynamics with greater transparency.
We have retained our signature Class A/B amplifiers used in every generation of Serie T since 2006. Reliability is the key to happy ownership and with some 200,000 and counting of this range leading long happy lives, Serie T/x owners can feel certain of REL’s standard setting reliability. The powerful 300 watt mosfet amplifier used in the T/9x remains an icon with huge reserves of current, massive power supplies but small upgrades are found everywhere. New driver mosfets that open up performance and transparency and new methods for securing the toroidal transformers mean better performance and superior strength.
REL’s legendary High Level Input connection and fast filters are a significant part of the REL story. Connecting via the speaker outputs of your amplifier without drawing any power from it may seem like magic, but the real magic lies in the way the sound takes on a natural character. Unique tuning and special limiters means the T/x range sounds fresher, faster and more dynamic than before.

The Greek letter mu (which looks like a "u", but pronounced "mew") is used in science and engineering to mean "micro" or one millionth. Here it signifies a speaker that is deceptively small in size, considering its big sound and performance.
But it has come to mean more - an approach to design that considers every detail, even the microscopic. We pay particular attention to how energy is dissipated, and keeping vibration to an absolute minimum, as not only do these result in
extraneous sound output, but the effect on the various components, including those in the crossover network, causes distortion. Our discoveries are applied to cabinet materials and construction, and the use of mechanical isolators for mounting drivers and crossover components.
We have come to refer to this discipline as "micro-vibration engineering" or "muve" (pronounced "move" - dare we say "sound that moves you"?)
With its smart new high-quality matt black finish or matt white finishes, the mu2 Mk II is much more than just a facelift, it's a totally new loudspeaker.
All elements - cabinet, woofer, tweeter, crossover - have been carefully re-examined and significantly improved, even where many thought no further improvement was possible.
Lessons learned from the original mu2 Special Edition (as well as our ongoing research into the effects of vibration on all components) - have been expanded upon, and now been applied to the mu2 Mk II. Constrained layer damping material has been custom manufactured for the mu2 by Les Davis Audio.
While the woofer and tweeter may look the same as the previous model, both have been improved with an even flatter response, smoother roll-off, and lower distortion. Enhancements to the crossover take full advantage of the above.
The new multi-layer cabinet construction now employs additional layers of differing materials, carefully chosen for
composition and thickness, for even further reduction in cabinet noise (vibration), energy storage, and coloration. Bracing has been further strengthened
With 1000’s more hours of listening tests and measurements, the cross-over region and on-axis to off-axis transition are even more seamless and even more difficult to detect (always outstanding features of the original design).
The mu2 Mk II takes detail and resolution to yet another level, as well as making the spatial presentation even more realistic. Soundstage and imaging are readily apparent, appropriate and precise in scale, and rock-solid - they don't appear to change or move.
Additionally, the speaker truly disappears, with listeners in our reference room unable to tell which speakers are playing.
Of course, the other attributes for which the mu2 is renowned (see Design Brief) have all been retained.
With 5 years of R&D and component testing, Serhan Swift found the optimum drivers to be a bass-midrange woofer and ring-radiator tweeter belonging to the premium Revelator series manufactured by renowned Scan-speak of Denmark.
These drivers are also found in much more expensive speakers from high-end companies such as Wilson Audio, Sonus Faber, and others—some costing well over $50K. Their use in a speaker at this price point is unheard of - pun Intended!
After extensive experimentation with low and high-order crossover configurations, a high-order crossover was ultimately chosen allowing for steeper slopes, to keep the drive units in their respective “power bands” and minimise out-of-band distortion. Whilst this increases component cost dramatically the audible benefits are very obvious.
The Cardas brand terminals are high purity copper with rhodium plating. Expensive, but audibly superior, reliable, and long-lasting. (Nothing has been overlooked. Attention to detail means you hear every detail).
Serhan Swift considers its products a long-term investment. Each pair of mu2 MKII’s take 3 days from start to finish under the watchful eyes of Chief Loudspeaker Designer Brad Serhan and Engineering Director Morris Swift.
