Miracle In Miniature

Tzero is, in many ways, the most difficult design we have ever executed because never before have we 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, our 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

Design

Scaled for the Simple Life

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 our larger models, there are plenty to choose from.

Driver

Outsized Performance

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 our 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.

Amplifier

Brains & Brawn

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. We feature the same high-quality input filters, crossovers and limiters as our larger models. Tzero MKIII includes a full REL connectivity suite, fast 8ms delay filter set and our 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.

Awards & Industry Reviews

“I can say without a doubt that these tiny REL’s excelled in becoming one with my monitors in a way I’d never really experienced prior…. Overall I fell in love with these little REL’s. They’re small, WAF (Wife Acceptance Factor) friendly, and in the right circumstances would be all you’re looking for in a two channel system.”

Outstanding Product

I have always felt a subwoofer points to a deficiency in the main pair of speakers, this, again, is not the case. I feel as if the subwoofer makes speakers more efficient and in the case of these two REL Tzero MKIIIs they are supporting the soundstage handsomely, without becoming too overbearing.

"I think the Tzero MKIII is a serious over achiever...the fact that it's so freaking tiny and beautifully finished, you could just tuck it away anyway. It has a lot going for it and it comes highly, highly recommended"

"I've enjoyed my time with this subwoofer. It was quite surprising in a lot of ways. I did not expect the things it did and the ways it delivered it. I think at the end of the day, in the right hands, for the right customer, I could see people saying that's the best $500 I ever spent."

"The Tzero III acquitted itself really well. It’s tiny, but that doesn’t stop it adding useful low-end grunt to speakers up to, say, £1,000. It also opens up their soundstage notably, a benefit that shouldn’t be underestimated. "
