REL HT/1003 MKII Subwoofer

The REL HT/1003 MKII Subwoofer delivers powerful, room-filling bass from a compact cabinet, combining a new 300W Class D amplifier with an upgraded 10-inch (250mm) CarbonGlas™ driver. Designed primarily for home cinema, the REL HT/1003 MKII delivers substantially greater output and headroom than its predecessor, while retaining the speed, control and musicality that make REL subwoofers so highly regarded. The REL HT/1003 MKII Subwoofer is available for demonstration in our Hull store by request.

With impressive low-frequency extension, high-output performance and refined analogue filtering, the REL HT/1003 MKII is an ideal choice for smaller and medium-sized home cinema rooms where deep, impactful bass is essential without the footprint of a larger subwoofer.

Powerful 300W Class D Amplification

At the heart of the REL HT/1003 MKII Subwoofer is a newly developed 300W Class D amplifier, engineered to provide greater headroom and sustained power. REL specifies its amplifier output as RMS Continuous, providing a meaningful indication of its real-world performance. The upgraded amplifier works alongside the redesigned driver to deliver dramatic increases in usable output, allowing the HT/1003 MKII to reproduce the explosive dynamics of movie soundtracks with greater authority while maintaining composure at high listening levels.

Upgraded 10-Inch CarbonGlas™ Driver

The REL HT/1003 MKII features a redesigned 10-inch (250mm) CarbonGlas™ driver, combining glass fibre and carbon fibre construction to create a lightweight, rigid and responsive cone. REL has upgraded the driver with a more powerful magnet system and improved suspension, including an enlarged surround that allows greater cone excursion. These enhancements enable the HT/1003 MKII to produce significantly higher levels of bass while retaining control and reducing distortion, delivering deep, powerful and fast bass from a relatively compact 10-inch subwoofer.

REL PerfectFilters™ for Deep, Controlled Bass

The REL HT/1003 MKII Subwoofer benefits from REL's refined PerfectFilters™ analogue filter technology. These circuits are designed to optimise the subwoofer's response, extending deep bass while helping the driver operate safely and cleanly at high output levels. A higher-frequency secondary filter extends the subwoofer's response further into the upper bass region, helping explosions, impacts and other low-frequency effects sound more immediate and realistic. An integrated analogue subsonic filter also helps control potentially damaging infra-low-frequency signals below the driver's useful operating range.

Compact Home Cinema Subwoofer

The REL HT/1003 MKII has been designed to provide high-output bass without requiring the space of a larger subwoofer. Its lower, sleeker cabinet takes design inspiration from REL's higher-end models while providing substantial internal volume for its compact footprint. The cabinet combines a premium piano-black top panel with a textured composite finish, giving the HT/1003 MKII a discreet but sophisticated appearance. Its compact dimensions make it particularly well suited to smaller and medium-sized home cinema systems.

Optional HT-Air™ Wireless Connectivity

For installations where running a traditional subwoofer cable is inconvenient, the REL HT/1003 MKII is compatible with REL's optional HT-Air™ wireless system. HT-Air uses a fast 5.8GHz wireless connection to transmit the LFE signal without compression, allowing the subwoofer to be positioned away from the AV receiver or processor without long RCA cable runs across the room. This makes the HT/1003 MKII particularly flexible for modern home cinema installations.

Built for Home Cinema and Music

Although the REL HT/1003 MKII Subwoofer is engineered with home cinema performance in mind, it is equally capable of enhancing music systems. Its combination of fast driver response, powerful amplification and carefully tuned analogue filtering allows it to add weight and scale while retaining the timing and definition required for high-quality music reproduction. For film, the HT/1003 MKII provides the visceral impact of explosions, sound effects and soundtrack bass, while with music it adds depth and authority to kick drums, bass guitars, orchestral instruments and electronic low frequencies.

Why Choose the REL HT/1003 MKII?

The REL HT/1003 MKII Subwoofer represents a major performance upgrade over the original HT/1003, delivering more power, greater headroom and substantially increased output from its compact 10-inch design. With a 300W Class D amplifier, upgraded CarbonGlas™ driver, REL PerfectFilters™, analogue subsonic filtering and optional HT-Air wireless connectivity, it provides an impressive combination of performance and flexibility. For anyone looking for a compact high-performance home cinema subwoofer, the REL HT/1003 MKII offers deep bass, powerful dynamics and refined control without the size or cost of a larger model.
