SKU: Tzero Category:


Tzero enriches even modest systems with power and natural bass, bringing the quality and full REL connectivity suite, long-throw drivers and powerful, reliable amplifiers to a new lower price point and dimension.

100% REL, Just Smaller

Tzero delivers so much for so little. 5 coats of lacquer, as in all Serie T/i, next-generation Class D amplifiers, High-level inputs, .1 separate input stages, rugged 6.5” main driver with exceptional output and low bass extension for its size means Tzero gives up little to much larger units from the competitors. Tzero is a miracle in miniature.

Compact Power & Finesse

Tzero is built using a super stiff cabinet construction that drives the resonant frequency higher so it’s more easily damped by REL’s instrument-grade bracing. REL utilize 5 full coats of lacquer, and solid aluminium feet and badging because REL owners understand quality must extend throughout a product, not just in the most obvious locations. And its diminutive scale allows it to all-but-hide among the furnishings in your home.

Bass Beyond Its Size

At REL every clean sheet design begins by defining and designing the best bass engine for a given application. While the long-throw 6.5” is REL’s smallest-to-date, but make no mistake, it’s powerful and articulate, able to fill medium-sized rooms effortlessly. Have a much larger space? Distribute them throughout for an unobtrusive spacious presentation of music and film sound.

Right-Sized Power & Control

Though Tzero is REL’s entry-level, that doesn’t mean it can’t punch far above its weight class. 100W high current watts from a NextGen Class D amp means it holds it’s head high and is capable of delivering many years of satisfying performance. Includes a full REL connectivity suite, fast 8ms delay filter set and our famed High-Level Input as well as a .1/LFE input.

Critic Reviews

“… in adding some air and space and speed to a good thin floorstander or a regular two-way stand-mount without breaking the bank, a REL T-Zero V2 (or preferably, two) can’t be beaten.” Click for full review
