Rethink What's Possible High-Performance Home Theater

The HT Series is designed specifically to meet the challenge of creating pure, exceptionally dynamic, and affordable home theater powered subwoofers. The HT/1205 MKII is the ideal combination of a lightweight, modern 12" (300 mm) CarbonGlas™ driver coupled with a powerful 500 W Class D amplifier that runs cool, producing stunning dynamics. In-house, we've developed specially adapted home theater input filters that produce extremely flat bass of up to 20.

We set out to build the loudest and relatively compact 12" unit available for pure home theater use, and at a very attractive price. You'll be the judge of how well we've achieved this, but the critics are already lining up to write reviews. We believe the HT/1205 MKII is destined to become a modern classic with slim cabinet dimensions finished in an attractive yet purposeful black grained aluminum look and topped with a beautifully polished 12mm thick top that serves to dampen vibrations on the cabinet's critical top surface.

For REL owners who already use our Reference, S-Series and T/i-Series subwoofers, designed for both 2-channel and theater use, the HT/1205 MKII is designed to complement the .1/LFE output of their system and produce extremely high output for chest-thumping home theater special effects.

Exterior Designer

The stunning new cabinet is custom-built; it features new textures, proportions and finishes never before seen in the category. The lower, sleeker cabinet borrows proportions from our new Reference models. Over the years, our experiments have shown that this translates into a faster and deeper bass presentation, all while looking spectacular. Your eye is immediately drawn to the top panel, whose entire surface is finished in 5 layers of hand-polished piano black lacquer. A subtle REL logo floats within the top layer of lacquer while the body of the cabinet is clad in horizontally grained composite. The whole thing looks expensive, bespoke and tasteful. Plus, you can pair it in style with the T/x Series or S Series in large, fully immersive REL HT/3D™ configurations.*

Drive Like You Mean It

The HT/1205 MK II's driver is a 12" (300 mm) CarbonGlas™ structure as it always has been, but all of its components have been strengthened. It's improved in both big and small ways, allowing it to deliver the highest possible performance. Lightweight, stiff and quiet, the combination of glass-fiber primary cones with real carbon-fiber hubcaps results in an affordable yet pistonic cone. Larger, more powerful magnets produce more energy. Improved suspension designs control the HT/1205 MKII's output to the limits of both the amplifier and driver. The result is insane output, while the HT/1205 MKII remains fast and liquid.

Now listen this!

Amplifiers do the heavy lifting in a theater subwoofer. We turned to a true top-tier amplifier supplier to help us build our latest project – and they didn’t disappoint. They included thicker boards, improved power supplies, and did everything necessary to make a brutally powerful amplifier with remarkable longevity. Plus, the 800-watt rated MOSFET power modules mean this amplifier is only cruising along at its 500-watt rated power. It produces truly impressive sound. While theater makes headlines, the big secret of the HT/1205 MKII is that it sounds sublime in music applications. Big and beefy sounding, it’s sure to become an instant classic.

PerfectFilters™: Where it all begins – Amplifier

REL input filters are renowned throughout the audio world. They pack ultra-fast crossovers, lift filters that extend the flatness of deep bass, and explosive-sounding built-in limiters. This compact set of analog circuits is REL's secret sauce for both music and movie sound. Refined in this second generation, the sub-filters are much higher in frequency; they make the rarefaction of air in the sound of an explosion much more realistic. Additionally, our latest circuitry includes an all-analog subsonic filter that starts as low as 8Hz to minimize the effects of infra-noise from movie soundtracks that extends well below the driver's resonance point. The result is incredible power delivery with the ability to play all the way to the driver's limit without distortion.

Wired for Sound: HT-Air

Wired for sound once meant long rows of cables strewn across the floor. With our optional HT-Air™, great sound just went "unwired." The cable has been replaced with a small transmitter and matching receiver that sends an incredibly fast 5.8Ghz wireless signal up to 60 feet without digital compression. This cost-effective circuitry includes the same LSIC chip that powers our cutting-edge AirShip II, without the expensive analog-to-digital and digital-to-analog converters (DACs). The HT-Air is perfect for .1/LFE signals using RCA connectors which is the primary mission of the HT/1205 MKII.

With a volume that is 6dB louder than any previous REL and a price that is 50% lower, the original HT/1205 was a remarkable value for the money.
