  • Passive Radiator: 10-inch

REL subwoofers 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 REL can do within any given technology envelope. As such, the T/9i represents the pinnacle of Serie T/i.

The combination of a lightweight, composite 10-inch driver coupled to a matching 10-inch 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. It’s powerful and concussive, yet beautiful.

A completely redesigned flagship
T/9i delivers more than just raw output. REL started with driver upgrades and then built outward. The lovely cabinets grew by 4 lbs. 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.

The brains behind the brawn
REL’s 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—wherein not simply the bass region but ALL music and movie sound is uplifted and improved.

Introducing Arrow™ Zero Compression Wireless
REL is quickly growing into an industry leader in 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.
