REL HT/1205 MKII Subwoofer

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.
