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 +

"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 +

Good Quality (when purchased)
Style: Unflavored (Pack of 1)
Genuinely the dream toothpaste I've been looking for since I don't like mint, its slightly sweet and the texture has a tiny bit of grit but overall its pretty good I'd say. But please be warned and look at the One star reviews, a lot of them are recent and are mentioning a change in the ingredients one of which said experienced a severe alergic reaction. A decrease in amount of toothpaste per tube, and lesser quality. I bought in bulk months and months prior but the one star reviews I've seen are all recent and oldest usually being from February. Heres hopes they change things back.

Doesn't improve breath but good for peeling
Style: Unflavored (Pack of 1)
I got this for two reasons: 1) regular toothpastes make my mucous membranes peel like crazy, 2) intense mint seems to heighten my post-nasal drip. This does not cause any peeling, which is great! The formula does foam up slightly, so it does feel like it is cleaning, if only gently. I'm not noticing a big difference with my post-nasal drip, which is okay, it was probably a long shot. The cons: The texture is quite runny and it seems like I have to use a lot to get the foam I'm used to. I know most people are using this because it doesn't have an intense flavor, but it does nothing to neutralize bad breath. I eat a lot of garlic and drink coffee, so it feels like I'm not freshening my breath much. It's also a bit pricey. I could see this being very valuable to someone with a true mint allergy, though.

The Best Fluoride-Free Toothpaste I've Tried
Flavor Name: 1. Sensitive Mint, Size: 5.25 Ounce (Pack of 1)
I've been using Davids Hydroxi Fluoride-Free Nano Hydroxyapatite Toothpaste for several weeks, and it has completely exceeded my expectations. The first thing I noticed was how clean and smooth my teeth felt after brushing. Unlike many natural toothpastes, it leaves a genuinely fresh feeling without being overly harsh. The natural peppermint flavor is refreshing and pleasant without the intense burn that some mint toothpastes have. What really impressed me is the nano-hydroxyapatite formula, which is designed to support enamel remineralization and reduce sensitivity. My teeth have become noticeably less sensitive to cold drinks, and they feel stronger overall. Nano-hydroxyapatite is gaining attention as a fluoride alternative because it can help replenish minerals in enamel and reduce sensitivity. I also appreciate that it's: Fluoride-free SLS-free Made in the USA Vegan Uses high-quality ingredients Comes in a recyclable metal tube The whitening is subtle but effective. My teeth look brighter without any increased sensitivity, and the toothpaste is gentle enough for daily use. The inclusion of xylitol and hydroxyapatite makes it feel like a premium oral care product rather than just another natural toothpaste. While it's more expensive than conventional toothpaste, the quality and ingredients justify the price. Even dental professionals reviewing hydroxyapatite toothpastes have noted benefits for remineralization, sensitivity relief, and plaque reduction. Overall: 5/5 stars. If you're looking for a fluoride-free toothpaste that supports enamel health, helps with sensitivity, and leaves your mouth feeling exceptionally clean, Davids Hydroxi is absolutely worth trying. Highly recommended!

Mild mint taste
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
I wanted to go fluoride free with my toothpaste so I decided to give this a try. I like that the flavor isn’t overly strong and it hasn’t caused any irritation at all. It doesn’t foam up as bad as my old toothpaste did. It is important to me that it’s all natural and fluoride free. My first check up at the dentist after using it went really well so it cleans your teeth really well. I would recommend it
