REL Paints the Town Bass: Colorful Subwoofers Crash High End Munich 2025

REL’s T/9X SE Subwoofers in French Racing Blue and Green With Envy™ debut at High End Munich 2025—because why should audiophiles settle for boring bass?

REL T/9x SE subwoofers in French Racing Blue and Green With Envy

REL Acoustics, long known for rattling floorboards and making neighbors question their life choices, is headed to High End Munich 2025 with two eye-catching new finishes for its T/9x SE subwoofer: French Racing Blue and the audaciously trademarked Green With Envy. At this point, it’s a toss-up who’s more color blind—REL or Tivoli Audio—but at least your low end will be dressed to impress.

Each T/9x SE packs REL’s high-level input—the secret sauce for tight integration with your main speakers—along with a fast, punchy 300-watt Class A/B amp that doesn’t sound like a cheap digital buzzbox. Up front, you’ve got a long-throw 10-inch driver doing the heavy lifting, backed by a down-firing 10-inch passive radiator that adds low-end weight without muddying the room. It’s built to hit hard, move fast, and stay musical—whether you’re spinning records or blowing up buildings on screen.

The new subwoofer finishes mark REL’s 35th anniversary—a nod to three and a half decades of doing bass better than most. It’s not just a birthday flex; it’s a reminder that REL’s been mixing precision engineering with real-world musicality long before DSP shortcuts and plastic cabinets took over. This milestone isn’t about looking back—it’s about doubling down on what matters: building subwoofers that don’t just rumble, but transform your music and movie nights into something visceral. It’s about precision, power, and making sure you feel every note and explosion right down to your spine.

Engineered for Eyes and Ears

French Racing Blue isn’t just a fancy paint job—it’s a nod to motorsport history, channeling that unmistakable electric blue once worn by Bugatti as it tore across the European racing scene. It’s a color that screams speed, precision, and a little bit of ego—all fitting for a subwoofer that’s tuned to move fast and hit hard without losing control.

Green With Envy™ doesn’t whisper—it struts. It’s bold, punchy, and just the right amount of unbothered, like a British racing green Jaguar E-Type parked in front of a pub full of Ferraris. There’s a spark of rebellion in this shade—kinetic, cheeky, and totally unapologetic—fitting for a subwoofer that refuses to blend into the background.

These new finishes roll into REL’s increasingly flamboyant pit crew of high-performance subwoofers, joining the likes of Italian Racing Red, Tangerine Dream, and the slyly trademarked Le Mon™ Yellow. At this point, it’s less a product lineup and more a Formula 1 paddock with better bass.

But it’s not all flash—under the hood, the T/9x SE gets a performance bump thanks to new carbon fiber center caps that shave 10 grams off the moving mass. That might not sound like much, but it translates to faster transients, tighter bass, and up to 1.2 dB more output than the stock T/9x. In audiophile terms: that’s measurable gains you can actually hear—and feel.

These new models aren’t just for folks chasing numbers—they’re for those who want their system to make a statement before the first note drops. It’s audio as identity, gear that reflects taste, intent, and just the right amount of swagger.

From John Hunter, REL’s Chief Designer: “This whole line is about shock and awe–about catching someone’s eye and having them say, that’s me,…”The SEs are for people who are expressive, passionate, and unapologetically bold in their love of sound. It’s not just performance–it’s personality.”

The Bottom Line

Subwoofers are a must-have for both music and home theater setups, but let’s be real—most people know REL’s lineup is built for music, even if they’re not afraid to shake the walls during movie night. While the original REL T/9X dropped in 2021, the T/9X SE—whether in its fresh color schemes or not—takes everything that made the original great and kicks it up a notch.
