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.

2.2 system

Added a second T7i in June’21 to form a 2.2 system (paired with bookshelf speakers). I had been using the first T7i for 18 months and I added the second T7i to make sure I had a matched pair as the model changed. Each T7i is connected with high-level input + LFE for the occasional movie. I noticed a clear difference with the second T7i as it helped fill my room even better. The responsiveness of the T7i allows is to blend seamlessly with the speakers and provide a wide soundstage with great punch while remaining in the background sonically. You can only locate them visually and they also look really good. Very happy so far and Indont anticipate any issues.

Great sounding sub

This is my second one so I run two for 2 channel Stereo. For my room which is pretty live, thr 7i's are more than enough subwoofer. They provide great low bass as well as add tight punchy bass when the music calls for it.

Alejandro Marquez
Excellent subwoofer

Great sound, excellent design and very easy to connect or integrate to your existing audio system. Looks great, sounds perfect.

ja Loh

Bought two Rel t/7i's, perfect with my Monitor Audio Silvers. Before the Rel's I didn't care for the boomy bass in with my old sub. This sub makes my whole system sound like it's a much more expensive set up then it really is. I love this sub.

Replaced my 17-year-old REL subwoofer

And I can hear music again
