We have a longstanding tradition of requiring the top model in any range to be more. More than the sum of its parts, it represents the grandest scale, the highest output and the most we can do within any given technology envelope.
The Most T/i Available
The Series Flagship
T/9i represents the most of T/i that we can deliver, and if sheer output alone is a primary requirement for your theater or music system then read no further. The combination of a lightweight, composite 10” driver coupled to a matching 10” T/i passive delivers speed, slam and attack when called upon but also is capable of tracing more delicate passages when necessary. Large in sonic scale, the T/9i is ideal for mating up with floor standing speakers and rooms that are on the medium-to-large size. Powerful, concussive, yet 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.
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.
Zero Compression Wireless
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.

"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."

“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 +

"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."
