Every T/x model boasts sleek, radiused designs and impeccable craftsmanship. But with the T/9x Special Edition, we’ve taken it a step further. It's the subtle details that elevates these models—the badge atop takes three days to perfect, and each solid billet aluminium foot undergoes a three-day chroming process. We meticulously layer copper, nickel, and chrome, allowing each coat a day to set before adding the next. This is the kind of attention to detail that makes REL stand out.

The Heartbeat of Every REL
Outsized Performance
Innovative Alloy/Fibre Bass Engines
To achieve higher output with better control requires a complete overhaul of the suspension components. Much like the suspension on a sports car, these items are responsible for the tuning and feel of our designs. By increasing the cabinet volume, efficiency is improved yielding higher output for no more amplifier power. Less back pressure inside the cabinet means we can tune for a stiffer, better controlled driver suspension. We retained the best aspects of our previous design, such as the aluminum center cap responsible for stiffening the lightweight 10” (250mm) cone while adding almost no mass. The updated combination produces considerably better attack and dynamics with greater transparency.
Tried and True Amplifiers
The Brains Behind the Brawn
We have retained our signature Class A/B amplifiers used in every generation of Serie T since 2006. Reliability is the key to happy ownership and with some 200,000 and counting of this range leading long happy lives, Serie T/x owners can feel certain of REL’s standard setting reliability. The powerful 300 watt mosfet amplifier used in the T/9x remains an icon with huge reserves of current, massive power supplies but small upgrades are found everywhere. New driver mosfets that open up performance and transparency and new methods for securing the toroidal transformers mean better performance and superior strength.
REL’s legendary High Level Input connection and fast filters are a significant part of the REL story. Connecting via the speaker outputs of your amplifier without drawing any power from it may seem like magic, but the real magic lies in the way the sound takes on a natural character. Unique tuning and special limiters means the T/x range sounds fresher, faster and more dynamic than before.
Standby Mode switch is only included on 220V units.
Amplified Emotion
T/9x's amplifier embodies power and precision with its 300-watt Class A/B monoblock design. Using reliable mosfet designs with integrated heat sinks, these amplifiers have been the driving force behind the Serie T flagships since 2007. With nearly 90,000 units in circulation—most in daily use—we take immense pride in their performance and dependability.
The streamlined 8ms input filters ensure a seamless blend between the subwoofer and speaker. With straightforward rotary analog controls for gain, crossover, and LFE Gain, and an intuitive 0–180-degree phase switch, setting up your REL is straightforward and hassle-free. No misplaced remote controls or complicated apps—just timeless, dependable engineering.
Standby Mode switch is only included on 220V units.
Wireless That Doesn’t Compress the Sound
Unlimited Possibilities
At REL, we’ve developed a sterling reputation for building the finest sounding, fastest wireless systems available in the industry. We never rely upon digital compression as it results in dull, lifeless sound. Instead, we have perfected an (optional) Arrow™ wireless system so fast and dynamic we’re comfortable encouraging the use of wireless on one channel of a pair of RELs while the other channel may be connected conventionally with cable.

They love it! Good quality toy.
Color: Orange
My dogs love this ball. The texture is perfect. They like being able to bite it. It doesn’t tear apart when they do either. Other interactive balls I’ve purchased have been hard plastic and much louder. Everyone is enjoying this toy more than those. It’s so fun to watch the dogs play with this. Video is from the first moment it arrived. They both play with it hard now. We’ve had it three days. I’ll update its longevity if it’s shorter than I feel it should be.

Keeps dogs busy.
Color: Orange
The dogs love this ball. They are afraid when it vibrates but as soon as it jumps and moves around, they are on it. They will play with it for quite awhile. Charge lasts for a long time. Very durable. This dog can tear anything apart but it's still in one piece.

Good for smaller jawed dogs.
Color: Orange
This ball is so much fun for our 5 month old. He both chases it and lets it bounce in his mouth. This was after playing with it already for 10 minutes. The ball charges with a usb charger and lasts for a long time. I do take it away to keep the toy fresh and prevent him from just chewing on it. I will say the ball startles you a bit when it turns on in your hand. Happy with a different toy.

Extremely durable, highly recommended!!
Color: Orange
This ball was a game changer for us!! I rehomed an extremely needy 110 pound one and a half year-old male Rott. This ball has been keeping him engaged for hours giving a much-needed break to me.😜 it actually stays charged a lot longer than I thought it would, and so far he is not chewed through it at all, which is incredible to me!! I think I’m gonna order another one so that I can have one charging while he plays with one and then switch off with them.
