It resets expectations for what's possible from a 10-inch subwoofer, delivering twice the output of its legendary predecessor. The MKII combines a new, lightning-fast 10-inch CarbonGlas™ driver with a cool-running and powerful 300-watt Class D amplifier. Purpose-built for the demands of the .1\/LFE channel, it features specially adapted filters to deliver stunningly deep and flat bass down to 24Hz. It’s the perfect solution for bringing explosive dynamics and tactile, room-filling bass to small and medium-sized theaters, all from an impossibly small cabinet.\u003c\/p\u003e\n\u003ch5\u003eKey Features\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e300W High-Current Amplifier:\u003c\/strong\u003e A powerful and reliable 300-watt (RMS) Class D amplifier provides massive headroom for explosive, high-impact dynamics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10” CarbonGlas™ Driver:\u003c\/strong\u003e A lightweight, stiff, and ultra-long-throw 10-inch driver designed for high output and speed, capturing every detail of an LFE track.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePure Home Theater Focus:\u003c\/strong\u003e Purpose-built for .1\/LFE, with specially adapted input filters and an analogue subsonic filter to produce deep, flat bass down to 24Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact, Elegant Cabinet:\u003c\/strong\u003e A sleek, low-profile cabinet with a line-grained composite finish, topped with a 15mm thick, hand-rubbed piano gloss lacquer top plate.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHT-Air™ Wireless Compatible:\u003c\/strong\u003e Pairs with the optional \u003ca href=\"https:\/\/listenroom.com\/products\/rel-ht-air-mkii-wireless\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eHT-Air MKII \u003c\/strong\u003e\u003c\/a\u003ewireless transmitter for a zero-compression, high-speed connection without long cable runs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDramatically Increased Output:\u003c\/strong\u003e Delivers a full 10dB higher output (twice as loud) as the original, award-winning HT\/1003.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eTwice the Impact\u003c\/h5\u003e\n\u003cp\u003eThe HT\/1003 MKII is a ground-up redesign, engineered to deliver a full 10dB higher output—making it twice as loud as the original. This incredible leap in performance comes from a new 300-watt Class D amplifier paired with an upgraded driver and all-new filters. This massive increase in usable headroom creates an effortless sense of ease, allowing the subwoofer to deliver savage, high-impact explosions and subtle atmospheric rumbles with equal poise.\u003c\/p\u003e\n\u003ch5\u003eThe CarbonGlas™ Driver\u003c\/h5\u003e\n\u003cp\u003eThe heart of \"The Hammer\" is its 10-inch (250mm) CarbonGlas™ driver. This composite cone is exceptionally lightweight and stiff, a combination that results in explosive dynamics and speed. The primary cone is made of lightweight glass fibre and is stiffened by a true carbon fibre center cap, creating a cost-effective yet truly pistonic cone. Paired with a more powerful magnet and an upgraded suspension, this driver can handle immense power and produce prodigious output, all while remaining as fast and liquid as any REL.\u003c\/p\u003e\n\u003ch5\u003eA Pure Theater Foundation\u003c\/h5\u003e\n\u003cp\u003eThe HT\/1003 MKII is a home theater purist. Its input filters are specifically designed for the demands of modern LFE, not music. A new, all-analog PerfectFilter™ lifts and extends the deepest bass, while a higher secondary filter allows energy to extend further up the spectrum, making explosions feel more realistic and savage. Finally, an analog subsonic filter removes signals below 20Hz that can cause damage and rob the amplifier of power, ensuring every watt is dedicated to producing clean, audible, and tactile bass.\u003c\/p\u003e\n\u003ch5\u003eSleek Form, Solid Function\u003c\/h5\u003e\n\u003cp\u003eThis subwoofer is designed to blend beautifully into any room. The cabinet is low and sleek, with a durable, line-grained black composite finish that is easy to maintain. This is crowned by a 15mm thick, piano-black top plate, polished in five coats of hand-rubbed lacquer. This top plate doesn't just look beautiful; its mass and finish serve to damp vibrations from the cabinet, ensuring all the energy is translated into pure, clean bass.\u003c\/p\u003e\n\u003ch5\u003eWireless Freedom\u003c\/h5\u003e\n\u003cp\u003eFor a clean, minimalist setup, the HT\/1003 MKII is fully compatible with REL's optional \u003ca href=\"https:\/\/listenroom.com\/products\/rel-ht-air-mkii-wireless\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eHT-Air MKII\u003c\/strong\u003e\u003c\/a\u003e wireless system.
