T/9i RED Ltd. Edition

A tradition has emerged at REL that once in a great while, we take an existing model that we consider to have special merit and imbue it with special characteristics. They are always rare, may even become collectible someday and offer a unique way to enjoy an already special model more deeply. But don’t wait, there are exceedingly few of these available and they will be gone very quickly.

The Most T/i Available

The Series Flagship

T/9i RED is what happens when we ask, “Wouldn’t it be lovely to produce a version of our best-selling T/9i in true Italian red?” (we stopped short of adding yellow graphics with a prancing horse as a badge). To get the hue exactly right required 14 months—we were bent on getting the exact shade of late ‘80’s cars from a certain factory in Italy exactly right because, after all, that is the color we think of when we think of exotic Italian GTs and sports cars. And then we couldn’t stop there because the look had to carry all the way through the design. Which explains the lovely triple-chromed top badge which then required a true carbon fibre bezel surrounding the badge to deliver the necessary transition from chrome to oh-my-goodness deep red. And we do sweat the minor details which explain the use of solid carbon fibre sleeves to anchor the bottom of the design.

Elsewhere, things remain the same which is to say it remains the standard setter in this category of affordable powerhouses that can do it all; Power home theatre? Check. Brilliant blend with main speakers for 2-channel performance? Check. The best affordable all ‘rounder just became rarer and more beautiful.

Reimagined, Then Reengineered

A completely redesigned flagship

T/9i delivers more than just raw output. We started with our driver upgrades and built outward. The lovely cabinets grew by 4 lbs. (1.8 kg) over its predecessor due to thicker cabinet walls and improved bracing. Why? Because the additional speed and impact of the new drivers requires greater control or the benefits can be lost before they get to the listener.

Outsized Performance

Innovative Alloy/Fibre Bass Engines

The new composite alloy/fibre engine in T/9i blends precisely the correct dimension of stiffening alloy with a fibre material chosen for its sonic neutrality and light weight. The combination is brilliant; exceeding the performance of competitors’ drivers that are many times more expensive. The forward-firing 10” active couples with a 10” down-firing passive, again with carefully chosen balances of alloy to fibre and the result is seamless, effortlessly deep bass that blends perfectly with the main speakers.

Great Subs, Great Amps

The Brains Behind the Brawn

Our acclaimed input filters and robust amplifiers result in some of the best sounding, most reliable designs ever produced. High current power supplies, huge toroidal transformers, and what many critics call the best filters in the world produce the famous REL Effect—where in not simply the bass region but ALL music and movie sound is uplifted and improved.

Standby Mode switch not included on 110V units.

Zero Compression Wireless

Introducing Arrow™

Following on the heels of the acclaimed LongBow™ Wireless, Arrow delivers much of the promise and connectivity of hardwired RELs with the placement flexibility and pure cool factor of great wireless for all of T/i. For a reasonable sum, Arrow gives you the ability to place subs in distant corners, along glass walls, or on hardwood floors where a cable would otherwise destroy the effect.

Reviews + Awards

"To some, the only thing better than a subwoofer is two subwoofers, and that was certainly the case when we tested the REL T/9i. While a single T9/i delivers the speed and depth we have come to expect from REL designs, the true strength of the argument comes when you use a pair of subwoofers, but not in the way you might expect."

I’ll be the first to admit that I didn’t hold out much hope in being able to integrate a subwoofer so easily into my current setup. Primarily due to not accounting for one over recent years and placing more and more furniture into the space, which in turn decreased the ability of positioning for such an addition. But I have to give great credit to the guys at REL Acoustics for creating a subwoofer which A. has the perfect range of controls to seamlessly take on the remaining last couple notes in the bottom end so well as well as fleshing out the midrange and treble very naturally and B. has such a fast and agile responsiveness that it kept up with the speed of my ceramic drivers.

Dan Worth, HiFi Pig

"I mentioned the use of two T9/i subwoofers, and what makes the addition of a second sub interesting is that unavoidable modes contingent upon the dimensions of the space, in other words the resonances, are less excited with this configuration. Use two subwoofers in different positions and you can run both at lower level than were one to be trying to fill the space with a single sub, one reason why two subwoofers are better than one, even two mid-sized ones rather than one large one. The drivers usually respond more quickly and, with less cone movement, can create the same sound pressure as one doing all the work alone, usually meaning distinctly less distortion and audible effortlessness."

"As I spend more time with the T/9i and the drivers settle in, I find it requires a slight reduction in level to continue to integrate unobtrusively with my setup. What it brings to the way a system handles recordings old and new is insightful, and one of the most rewarding additions to my hi-fi setup in recent times, allowing the main loudspeaker to do its thing, but even more so."

Lee Dunkley, Hi-Fi Choice

“REL’s T/9i is an excellent subwoofer for the audiophile. It’s capable of making big bass noises, but is also more than capable of freeing up the loudspeakers and liberating them from the dictatorship of the room. While there is no substitute for huge bass traps and other room treatments, a pair of T/9i get you most of the way there without the domestic angst room treatment can cause. Highly recommended” Read More +
