Smaller does not mean lesser. We designed the compact T/5i to give smaller sized spaces and systems equal quality sound, so while scale may change the performance stays the same.Find a Dealer

A 360-degree Upgrade
When we upgraded our drivers, we were forced to redesign outward. The lovely cabinets grew 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.
Faster & Deeper
We began by updating our classic 8” bass engine to reduce mass, while greatly increasing stiffness. This improvement led to upgrading cabinet dimensions and wall thickness to better control the deep bass. Additional upgrades extended even into the design of our feet, resulting in greater speed and solidity to the presentation of sound.

I'm delighted with my new REL T5/i to say the least. I only have a few hours on it, but the speed and midrange and scale the REL T5/i is already giving to the KEF LSXs is gorgeous. Oh, and the bass extension is incredible too!
On this video from you guys https://youtu.be/8bNVHV_q1qk I need to take my family out for dinner for two hours to break it in 🤣!
Never owning or using a sub in my entire life, this subwoofer has improved my listening experience tremendously. I can feel the music experience as well with superb low frequencies. The quality of this sub is outstanding, you don't see superb quality much these days. I did not want an average subwoofer, so I went right to the top of the list and REL went beyond my expectations!
I've had my T/5i a few days now. I really like the way this sub pressurises the room. You might think because of it's size there's no way.
I own Earthquake, Cerwin Vega, Paradigm and Velodyne subs. I truly prefer this one overall. So if you take the time to follow the instructions that comes with this sub,it should be all you need.
I have purchased my first REL sub this week, T-5i, and it’s truly amazing, by far one of the best things I have brought for my Hi-Fi, I now realise I have been missing 50% of the music, the sound stage this REL produces is remarkable. It's more then just bass, it completes the sound stage of a Hi-fi system, and I would never go back.
The sound quality of bookshelf speakers have reached the golden age of hifi. My only gripe with the types of small speakers I own is with the unsatisfying low frequency extension and density. All of my small speakers benefit greatly with the addition of the T/5i subwoofer. From my experience the REL high level connection sounded best with single cone full range speakers paired with class A, single ended triode amplification, 300B’s if you know what I mean. For my class A/B amp using 2-way speakers with passive crossovers within, the low level input signal sounded best for me. Choose cohesive or coherent either way my overall sound fidelity has greatly improved with the T/5i. I like near field and typical living room spaced dimensions, so small speakers are my first choice. Matching the subwoofer scale to the scale of the room dimensions is a major consideration. My T/5i is at the limit of what I want to work with in terms of the size and placement of a subwoofer. If I am going to scale up the output of my stereo systems I’ll use speakers with larger woofers first. Overall my impression of the T/5i is highly recommended. The build quality meets a very high standard the best I’ve seen. For bookshelf speakers the T/5i is essential. It can improve the sound quality of the very competitive small speaker market making making the price to performance ratio on this subwoofer high

“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 +

"As REL woofer-in-chief John Hunter described to me, the new T lineup benefitted from the development of the Series S line. The Series S reminded him not only of the importance of both a lighter/stiffer driver but of the issue of self-quieting, which Hunter describes as design and engineering 'intended to produce a cone/driver that starts and stops well and immediately quiets down and does not continue ringing.' Basically, no overshoot." Read More +
