The Perfect Answer For The Real World
T/7x is compact enough (and beautiful enough) to end arguments before they begin; while powerful enough to easily answer most needs and balanced enough to blend beautifully with many of the quality speakers out there and still flexible enough to work in specialty applications.

Filtered for Purity! THE PRACTICALLY PERFECT REL!
REL’s legendary High Level Input connection and fast filters are a significant chapter in 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 and blends seamlessly with your speakers. Unique tuning and special limiters means the T/7x sounds fresher, faster and more dynamic than before.

ST/7x is, without reservation, one of the most-balanced RELs of all time. In order to achieve perfect balance, a sub must weigh speed against heft, while ensuring true extension-depth-and do so in a physically harmonious package. T/7x manages to make it all seem easy. Quick and delicate for a perfect blend, it can pound out exceptionally deep, tuneful bass that belies its size and plays louder than most will ever require.

Designed to be Better
Many don’t realize the intense connection between performance and design here at REL. Performance is everything to us and it leads to physical design solutions. Thus it is, that our engineers, in recognizing the need for greater cabinet volume to achieve the goals of greater fluidity and power, turn to the designer. He 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 clean with no unnecessary adornment.

Drive On! INNOVATIVE ALLOY/FIBRE BASS ENGINES!
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.

Tried and True Amplifiers! THE POWER BEHIND REL
REL has retained their 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.

Standby Mode switch is only included on 220V units.

Zero Compression Wireless! UNLIMITED POSSIBILITIES!
At REL, they have developed a sterling reputation for building the finest sounding, fastest wireless systems available in the industry. REL never rely upon digital compression as it results in thin, lifeless sound. Instead, they have perfected an (optional) Arrow Wireless system; so fast and dynamic they’re comfortable encouraging the use of wireless on one channel of a pair of RELs while the other channel may be connected hardwired with cable.

Sound Illuminated - THE ULTIMATE UPGRADE
Bassline Blue is a sensibly-dimensioned cable, well-constructed so that it will improve the overall sound of every aspect of the host system’s performance. As with any REL product - the improvement extends well beyond the obvious bass region. The greatest area of improvement lies in the manner in which the entire soundstage is illuminated. This is a quality quite different from brightness. Illumination acts to bring light into the stage and renders contrast and clarity as well as dynamic shadings much more evident.

What’s In a NAIM? These same benefits are available to most NAIM owners - especially the older, classic models. These units feature an unusual output impedance that is quite complex. REL worked closely with NAIM engineers to model this behavior and arrived at a special circuit built into each NAIM cable that replicates this impedance so that it is safe to run Bassline Blue on early NAIMs. We even sourced a wonderful stackable banana plug that makes it so easy to use the cables, just plug them in to NAIM’s flush-mounted chassis banana sockets and then plug your speaker cables directly into the rear of our stackable banana plug.

Natural Drawn Copper - QUALITY BORN FROM SYSTEM THINKING
Beyond optimizing the geometry of the internal lay of the cable, REL also employs copper that exceeds industry practices and is of a quality and type generally specified for military use and high speed telecommunications. Bassline Blue is constructed of slow-drawn, high purity copper, drawn in a nitrogen bath to minimize impurities on the surface of the wire. Each individual conductor is coated in a Teflon film immediately upon leaving the extrusion die to ensure that impurities cannot impinge on the cable while awaiting further processing. This technique produces a sound that is exceptionally pure and natural which REL terms Natural Drawn wire. Bassline Blue is hand constructed at REL's California facility using cable produced exclusively to REL’s specification by a North American OEM wire and cable house. Construction is quite labor intensive and can require up to one hour per cable. REL uses pure silver solder for all connections which ensures not just high quality sound, but also as the cable ages and oxidation sets in sonic degradation should be nil due to the conductive properties of pure silver.

HIGH LEVEL = HIGH PERFORMANCE
REL employ Swiss-made Neutrik SpeakOn connectors at the input to the REL sub bass system. In over 100,000 RELs in use the world over, this connector has proven itself reliable, neutral and a mechanically ideal connector for REL’s renowned High Level Input circuitry. BLUE also features high quality spade lugs coated in gold to minimize oxidation. Should your amplifier require a bare wire connection, this is easily accommodated by manually re-terminating the individual red, black and yellow leads. The standard high-level hookup procedure is: attach the red wire to the amplifier’s right positive speaker output terminal; attach the yellow wire to the amplifier’s left positive speaker output terminal; attach the black wire to whichever of the amplifier’s ground output terminals is convenient; plug the Speakon connector into the Sub-Bass system’s high-level input.
