Balance Point

The Perfect Blend

T/7i is, without reservation, one of the most-balanced RELs of all time. In order to achieve perfect balance, a sub must weigh speed against heft, while ensuring true extension-depth-and do so in a physically harmonious package. T/7i manages to make it all seem easy. Quick and delicate for a perfect blend, it can pound out exceptionally deep, tuneful bass that belies its size and plays louder than most will ever require.


Reimagined, Then Reengineered

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.


Outsized Performance


The new composite alloy/fibre engine in T/7i 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 8” active couples with a larger 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.


Brains and Brawn

The Power Behind REL

If our driver designers deliver the structure of REL’s sound, the electronics are the brains and the power behind our success. Serie T/i uses the same Class A/B power amplifier sections with large, high current power supplies, precision-wound toroidal transformers and an amazing reliability record that has powered almost 100,000 RELs. Our proprietary filter designs are responsible for rave reviews for REL’s unique ability to blend seamlessly while layering on all the harmonic structure missing from conventional systems.

Standby Mode switch not included on 110V units.

Great sub!

Great sub, lots of slam, integrates nicely with main speakers.

Great subwoofer - Integrates well with the existing system

I owned a few subwoofers including Martin Logan, SVS, Paradigm millennium. After talking to different retail HT experts, I bought this based on quality, size, and price. I liked that fact that Amazon offered free return shipping back too. So, I tried it. It worked great with my paradigm floor standing speakers. It produces deep and tight rich sound. I was very impressed with the sound quality. I had to spend some time in fine-tuning, including the placement of the subwoofer. I found out that my room needs a little more powerful subwoofer than what I thought. One small thing I noticed was there was a little dent in the outer finish when I unboxed it (I followed their instruction how to unpack to avoid scratches).

Overall, I liked REL Acoustics T/7i sound quality.

REL T/7i with Apogee Duettas

The pair of RELs brings new life to these great speakers. Excellent sub.


En México, no es fácil encontrar productos tan extraordinarios como los subwoofers REL. Yo tengo un subwoofer T7 y, desde que lo añadí a mi sitema de audio middle end, los resultados auditivos han sido increíbles. Desde luego mucho tiene que ver la paciencia para encontrar el punto exacto de colocación del subwoofer, acomodar el crossover, etcétera; sin embargo, aun sin llevar a cabo estos delicados ajustes, el subwoofer suena precioso. Los felicito porque mi subwoofer hizo perfecto juego en mi casa.

T/7i Fit Perfectly into My Stereo System

T/7i fit perfectly into my stereo system which composed of two Dali Sceptor book shelf speakers. The enhanced deep sound comes as though directly from the two bookshelf speaker, I simply cannot hear the existance of the subwoofer.
