REL T/7i Black Details

REL Acoustics T/7i Powered Subwoofer (Black): Perfectly balanced between speed and heft

  • Front-firing active woofer, down-firing passive radiator
  • Active Drive Unit: 8-inch long-throw, inverted dust cap, steel chassis
  • Passive Radiator: 10-inch
  • 200-watt (RMS) Class AB digital amplifier

  • Input Connectors: Hi Level Neutrik Speakon, Lo Level single phono, LFE phono

The REL T/7i powered subwoofer 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.

Simply faster: Experience a better engine
The new composite alloy/fiber engine in T/7i blends precisely the correct dimension of stiffening alloy with a fiber 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-inch active couples with a larger 10-inch down-firing passive, again with carefully chosen balances of alloy to fiber and the result is seamless, effortlessly deep bass that blends perfectly with the main speakers.

Brains and brawn: The power behind REL
The electronics are the brains and the power behind REL’s success. Serie T/i uses 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.

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.

Zero Compression Wireless with Arrow™
Arrow™ is REL’s latest generation of zero compression wireless transmission. Its incredibly fast delivery of both High Level Bass and .1/ LFE ensures REL’s distinctively rich, natural warmth for both 2-channel music and multichannel home theater. With a throw distance of some 45 feet, Arrow permits flexible placement of T/i sub-bass systems without sacrificing sound quality.
