REL T9i Subwoofer

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 T 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.

Outsized Performance - 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 ar10 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

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 - Introducing Arrow™

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.
