T/9x

Serie T/9x: Bigger and Better

The job of any range topper for REL is to deliver more of everything, particularly output and dynamics. The 9x is no different in this regard, as it delivers the goods in both music and theatre applications. 9x, however, delivers a level of intimacy, clarity and speed that means there are no longer trade-offs between the sonic balance of smaller models weighed against the power and scale of a model 9.

The all new 9x has even greater output than before, but the headline news is the way it sacrifices nothing in clarity and transparency to achieve this. At this price it opens the pathway for owners of high-performance European floor and stand mounted monitors and smaller panel speakers to enjoy truly full range sound.

Design

Reimagined, Then Reengineered

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.

Driver

Outsized Performance

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.

Amplifier

Tried and True Amplifiers

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 mean the T/x range sounds fresher, faster and more dynamic than before.

Standby Mode switch is only included on 220V units.

Wireless

Wireless that Doesn’t Compress the Sound

At REL, we’ve developed a sterling reputation for building the finest sounding, fastest wireless systems available in the industry. We never rely upon digital compression as it results in dull, lifeless sound. Instead, we have perfected an (optional) Arrow™ wireless system so fast and dynamic we’re comfortable encouraging the use of wireless on one channel of a pair of RELs while the other channel may be connected conventionally with cable.

Awards & Industry Reviews

AV Forums Highly Recommended

When you get it out of the box the superior build quality, attractive design and gorgeous finish provides an immediate feeling of luxury. It's not all looks either, and this discreetly-compact subwoofer does an awful lot with its 10-inch driver, 10-inch passive radiator and 300W of Class A/B power.

T9x Review by Spare Change

“Textures, layers and fast attacking response were some of the best I’ve heard in my home. They can be aggressive for Rock music or nuanced during live performances, and this all applies to home theater as well.”

Home Cinema Choice Highly Recommended

“I was amazed at the T/9x’s ability to energise the room without sounding woolly or frayed. It also managed to deliver powerful bass while retaining REL’s trademark speed and flair. This is a remarkable achievement in terms of redesigning and reengineering an existing product, and one that’s sure to please existing fans of the brand. It should also make it plenty of new ones.”

What the new REL /x subwoofers bring to your system, in addition to more bass output, is a higher level of definition in the lower frequencies, as well as more presence in the entire frequency spectrum...The best way to really experience what any REL subwoofer can do is to shut it off. The 30 seconds you hear your system with it disabled will convince you. That’s truly all it takes.

Tone Exceptional Value Award

"As with every REL-based system I’ve set up over the years, when properly set up the RELs are undetectable, until you turn them off. In addition to the lowest bass fundamentals diminishing, the front to back imaging component of the system nearly disappears. Even when listening to music that doesn’t have a ton of heavy bass. The level of depth that the REL subwoofers provide never ceases to amaze me."

"REL has done it yet again by producing a subwoofer that literally punches above its weight. The T9X is fast, authoritative, can untangle complex bass lines and can convey great detail all the way down to the deepest notes."

"I really believe the hero of any system has gotta be the subs. Your home theater or your stereo, and what I felt here was not just a sense of being surrounded or being immersed in the sound track. Now, you’re actually embedded."
