REL T5i Subwoofer 125W 8"

In stock
From $1,199

Smaller does not mean lesser. REL designed the compact T/5i to give smaller sized spaces and systems equal quality sound, so while the scale may change the performance stays the same.


REL T5i - Stunningly simple

Simplify, then add lightness: Simplicity is its own reward and the T5i reduces the classic cubic sub to its bare essence. A single, high-quality AlloyFibre composite driver and down firing orientation produces maximum coupling with the floor and eliminates the need for a grille. The T5i is the purest expression of REL.

- Closed Box, Down-Firing Woofer
- Custom Design 8" Long Throw Driver
- 125 Watt Class AB Power Amplifier
- Hi-Level, Lo Level & .1 LFE Inputs
- 32Hz at -6dB in-room frequency response

Reinforced Simplicity - A 360-degree upgrade

The REL T5i features an updated 8" bass engine to reduce mass, while greatly increasing stiffness. This improvement led to upgrading cabinet dimensions and wall thickness to better control the deep bass. Additional upgrades extended even into the design of the sub's feet, resulting in greater speed and solidity to the presentation of sound.

Proven Power - REL's reliable brains & brawn

REL's electronics are the brains and power behind their success. Serie Ti subwoofers use Class A/B power amplifier sections with large, high current power supplies, precision-wound transformers and an amazing reliability record that has powered some 100,000 RELs.

Optional Accessory - ARROW (Zero Compression Wireless system)

Arrow Zero Compression Wireless: REL are quickly growing into an industry leader in wireless. Following on the heels of the acclaimed LongBow Wireless system, Arrow delivers much of the promise and connectivity of hardwired REL's with the placement flexibility and pure cool factor of great wireless for all of Ti subwoofers. 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.

ARROW is an optional accessory, available separately HERE

Serie T/i

The completely reimagined Serie T/i provides the most power and performance of any subwoofer in its price range. The perfect combination for smaller to mid-sized home theater systems and rooms.

We prefer to refine, to build generationally upon a solid foundation while searching relentlessly for every possible way to legitimately improve upon our past performance. T/i represents a new standard for overall performance in this price category with upgraded drivers, cabinets, amps, and even zero-compression wireless capability when paired with our new Arrow™ wireless system.
