Building on the original HT\/1205, the MKII delivers up to 50% greater output while combining a redesigned CarbonGlas™ driver, a powerful 500-watt Class D amplifier, refined PerfectFilters™ analogue circuitry, and a compact, heavily braced cabinet designed specifically for high-performance home theater systems. Its lightweight glass-fibre cone and true carbon-fibre center cap are supported by larger magnets and an upgraded suspension system for tremendous output with fast, controlled performance. The redesigned amplifier incorporates thicker circuit boards, an upgraded power supply, and MOSFET modules rated at 800 watts, giving its 500-watt output substantial operating headroom. REL's second-generation PerfectFilters™ circuitry combines ultra-fast crossovers, elevation filters, integrated limiters, and an all-analogue subsonic filter beginning at 8 Hz to deliver controlled bass extending into the 20 Hz range. A lower, sleeker cabinet with solid bracing, a 12mm-thick vibration-damping top panel, five coats of hand-polished piano-black lacquer, and line-grained black composite bodywork gives the HT\/1205 MKII a premium appearance to match its performance. Designed primarily for .1\/LFE reproduction, it can supplement other REL subwoofers in high-output theater systems, integrate into REL HT\/3D™ installations, and use optional HT-Air™ technology for uncompressed 5.8 GHz wireless transmission up to 60 feet. Despite its home theater focus, the HT\/1205 MKII also provides the speed, weight, and articulation needed for compelling music reproduction.\u003c\/p\u003e \u003ch4\u003eWhat It's Good
