100% REL, just smaller

Tzero is, in many ways, the most difficult design REL have ever executed because never before have they delivered so much for so little. Five coats of your choice of black or white high gloss lacquer as in all Serie T, NextGen Class D amplifiers, their famous High Level Input, plus a separate .1/LFE input stage with its own volume control to get theatre levels AND music perfect without racing to adjust or looking for a remote control.

The jewel of the MKIII is the new aluminum-coned driver, a rugged 6.5” unit with exceptional output and low bass extension for its size. While it won’t drive medium or large rooms hard, we make plenty of larger models that handle that task, Tzero MKIII remains a miracle in miniature.

compact power & finesse

At REL every design begins by defining and designing the best bass engine for a given application. With its new aluminum-coned long throw 6.5” driver, the MKIII is powerful and articulate, delivering surprisingly deep bass. Able to fill smaller spaces effortlessly. Have a much larger space? Turn to one of REL's larger models, there are plenty to choose from.

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 is 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 MKIII is REL’s entry level, that doesn’t mean it can’t punch far above its weight class. 100 high-current watts from a NextGen Class D amp means it holds its head high and is capable of delivering many years of satisfying performance. It features the same high-quality input filters, crossovers and limiters as REL's larger models.  Tzero MKII includes a full REL connectivity suite, fast 8ms delay filter set and their famed High Level Input as well as a separate .1/LFE input with its own level control and a standby circuit that reliably comes alive at very low levels.
