REL T/5i Subwoofer


Purity Reimagined
Stunningly Simple
Simplify, Then Add Lightness: Simplicity is its own reward and T/5i 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. T/5i is the purest expression of REL.

Reinforced Simplicity
A 360-degree Upgrade
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.

Faster & Deeper
We began by updating our classic 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 our feet, resulting in greater speed and solidity to the presentation of sound.

Proven Power
REL's Reliable Brains And Brawn
REL’s electronics are the brains and power behind our success. Serie Ti uses the same 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.
