Tzero MKIII

Tzero MKIII is every bit a true REL, just smaller. It enriches even modest systems with power and natural bass by bringing the quality and full REL connectivity suite along with an all-new aluminum cone that provides much greater stiffness to the driver for punch and a powerful, reliable Class D amplifier, all at an attractive price point and size. Ideal for apartments, flats, studies, anywhere space is limited.

Miracle In Miniature

100% REL, Just Smaller

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

Scaled for the Simple Life

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 our larger models, there are plenty to choose from.

Outsized Performance

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 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.

Brains & Brawn

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. We feature the same high-quality input filters, crossovers and limiters as our larger models. Tzero MKII 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.

Reviews + Awards

“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.” Read More +

Matthew Philpot, Everyday Audiophile

"This is The Little Sub That Could. The REL T-Zero isn’t meant to be compared to the big guns, but in a way the small-cones make them extremely fast, and that is a perfect foil for high performance audio systems.” Read More +

Very nice if you aren't too pick on actual color.
Size: Single Pelt/2 ft x 3 ft, Color: Blue
Colors may vary. I really liked this, it was the perfect size and that perfect combination of soft and fluffy, but not being "too fluffy" and looking like a shaggy dog that needed a haircut. My only complaint was the color. Supposed to be blue, and I know monitors and lighting distort stuff but this was an obvious turquoise/teal. Much much greener than I was looking for. I could have made any variant of an actual blue work from powder baby to practically navy, but not this. I had to return, but other than the color, this seemed to be a very nice rug. Sad the color was so off.

Soft and comfortable. Quality leather nsckrd. Genuine sheepskin. No off odors. I'm skinny and not on tailbone. Hoping this helps. The grey tipped is more of a bluish gray. Pretty but not s true gray.
