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.
Standby Mode switch not included on 110V units.
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.
Excellent sound within a beautiful cabinet
Just got my product of the T9-i and I am simply stunned at the amount of bass it puts out. I have it paired with an HT-1205 and have ao much head room! So thankful for Best Buy showcasing these products to test out! Thank you REL for producing such a musical subwoofer!!!
I have my music and home theater in the same room - sharing same power amp for front channels (thanks Parasound). I was looking for something that would give me the proper bass for movies without too much for my music.
The REL T/9i is the answer.
By hooking up the high-gain connection to my power amp and also the LFE to my Home Theater amp; I have the perfect mix.
I tried the REL, Polk, Speedwoofer and AVS all at the same time - there was a major difference when it came to the audio quality for my 2 channel music listening.
Thank you REL for making amazing products and the in-home trial is wonderful.
Not much into writing reviews, but figured it may help someone debating between the T9i and the T7i. Could never find a review directly comparing the two by someone who owned both. I opted for the T7i in my main listening room, but always wondered over the past 2 years if I should of went with the T9i. Taking advantage of the March sale I purchased a T9i, and moved the T7i to the bedroom to pair with my LS50's (match made in heaven). At lower volumes the T7i is more than adequate, but at increased volumes the difference is not subtle! Effortless would probably the best 1 word adjective. On paper 2 additional Hz lower extension and a 10" driver vs 8" might not seem like much difference. Stretch your budget, or save awhile longer - you won't regret it! Specs do not tell the whole story, unless you've heard a REL T series with class A/B amplification using the Neutrik Speakon input you just wouldn't understand and appreciate what they are capable of in a 2 channel system.
Purchased a T9i from Sam at Sevenoaks Sound and Vision in Nottingham, UK after the essential home demo. Sam got Rob Hunt from REL to advise along the way. I received exceptional customer service, far beyond what you normally get, from both so thank you. The T9i is a great product. A Subwoofer was not something I would have considered as my next upgrade as primarily a HiFi enthusiast but what an upgrade! I will be adding a second REL to my system in due course. I highly recommend any Subwoofer sceptical HiFi enthusiast to look into REL. It gives you so much more than just full frequency in your system. I will say no more and just leave you to be gobsmacked by the "REL effect" when you try for yourselves!

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.

"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."

“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."
