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.
The HT/1205 MK II’s driver is a 12” (350mm) 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.
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.
