HT/1205 MKII (a.k.a The Cannon)
HT/1205 MKII establishes a new performance standard for affordable home theatre subwoofers. Avoiding electronic gimmickry in favor of properly balanced priorities; cabinets that are right-sized, solidly braced and beautifully finished. A sparkling new amp design that effortlessly delivers 500W into an all-new CarbonGlas™ 12” (300mm) driver. The sexy new black lacquer top plate has a subtle REL logo floating on top, while the expensively wrought black line-grained composite for the cabinet looks the business.
HT/1205 MKII plays 50% louder than its predecessor, while also delivering more precision and subtlety. It is capable of output levels more commonly found in models well over $1,000/£1,000. Fantastic for music and available HT-Air rounds out a perfect offering.Find a Dealer

The beautiful new cabinetry is bespoke; it has new textures, proportions, and finishing touches previously unseen in the category. Lower, sleeker cabinetry borrows proportions drawn from our new Reference models. Over the years, our experiments have established that this results in a faster, deeper presentation of bass—all while looking smashing. Your eye is immediately drawn to the top panel, whose entire surface finished in 5 coats of hand-polished piano black lacquer. A discreet REL logo floats within the top layer of lacquer whilst the body of the cabinet is clad in horizontally streaked, line-grained composite. The entire affair looks expensive, bespoke, and tastefully restrained. Additionally, you can stylishly combine it with either Serie T/x or Serie S in large, fully-immersive REL HT/3D™ setups.*
Drive Like You Mean It
The HT/1205 MKII’s driver is a 12” (300mm) CarbonGlas™ construct as it has always been, but all its components were beefed up. It is improved in both large and small ways, enabling it to deliver the greatest performance possible. Lightweight, stiff, and quiet, the combination of glass fibre primary cones with true carbon fibre centre caps results in a cost-effective yet pistonic cone. Larger, more powerful magnets produce more energy. Upgraded suspension designs control the HT/1205 MKII’s output all the way out to the limits of both the amplifier and the driver. The result is crazy output, while the HT/1205 MKII remains fast and liquid.
Now Hear This!
Amplifiers do the heavy lifting in a theatre subwoofer. We turned to a true tier one amp supplier to build our latest design for us—they did not disappoint. They included thicker boards, upgraded the power supplies, and did all the stuff that results in a brutally powerful amp with remarkable longevity. Additionally, the MOSFET power modules rated at 800 watts mean this amp is just cruising at its 500-watt rating. It produces truly awe-inspiring sound. While the theatre gets all the headlines, the HT/1205 MKII’s big secret is that it sounds sublime in musical applications. Big and robust-sounding, it is sure to become an instant classic.
PerfectFilters™: Where it All Starts – Amplifier
REL input filters are renowned throughout the audio world. They bring together ultra-fast crossovers, elevation filters that extend the flatness of deep bass, and explosive-sounding integrated limiters. This compact series of analogue circuits is REL’s secret recipe in both music and film sound. Refined in this second generation, the secondary filters are much higher in frequency; they make the rarefaction of air in the sound of an explosion to feel that much more realistic. Also, our latest circuit includes an all-analogue subsonic filter that begins as low as 8 Hz to minimize the effects of infra-noise from soundtracks that extends well below the resonance point of the driver. The result is incredible delivered power with the ability to play all the way to the driver’s limit without distortion.
Wired For Sound: HT-Air
Wired for sound used to entail long runs of cable strewn across the floor. With our optional HT-Air™, great sound has become “un-wired.” Wire has been replaced by a tiny transmitter and matching receiver that sends an incredibly fast 5.8Ghz wireless signal up to 60 feet with no digital compression. This affordable circuit includes the same LSIC chip that powers our state-of-the-art AirShip II, minus the expensive analogue-to-digital and digital-to-analogue (DAC) convertors. The HT-Air is perfect for the .1/LFE signals using RCA connectors that are HT/1205 MKII’s primary mission.
At 6 dB louder than any previous REL within 50% of its price, the original HT/1205 was a remarkable value.

"The power the REL Acoustics HT/1205 MKII brings to music and home entertainment systems is remarkable at the price. The 500W power output rating really does seem under-specified as this potent performer will easily drive medium-sized rooms without breaking a sweat, and there’s plenty in reserve to drive even larger rooms should circumstances require."

"The HT/1205 MKII is yet another fantastic sounding subwoofer from REL’s Serie HT. It’s attractively designed with a gorgeous CarbonGlas driver that should see the grille left firmly in its box. Its relatively unobtrusive dimensions mean the REL could grace an owner’s living room without drawing too much attention to itself. What’s more, the HT-Air was a revelation in ease of use. It took seconds to set up and did away with the need to hide unsightly wiring." Read More +
"The REL HT/1205 MKII is another beautifully built subwoofer from REL’s Serie HT line of home theatre-aimed subwoofers. It delivered an authoritative low-end performance, with a highlight being its ability to reproduce punchy, tactile bass impact. It will not plumb subterranean ultra-low frequency depths, but that doesn’t reveal itself at normal listening levels." Read More +
