For when there is simply neither the space nor the need for all the output of a larger HT model. HT/1003 applies the same approach as its impressive stablemate and scales it down by just a little. 10” high-powered, long throw driver and 300W means it has plenty of power on demand. This unit is intended primarily for high-powered home theater applications, immersive gaming set-ups, and pairs nicely with active powered loudspeakers. Scaled-down design, up-sized performance.

REL's home theater-focused Serie HT line is designed specifically to answer the challenge of affordably priced, highly dynamic pure home theater powered subwoofers in a handsome, compact package that makes it easy to tuck a few of these into most environments. The HT/1003 combines a lightweight, modern 10” CarbonGlas™ (250 mm) driver, coupled to a powerful 300W Class D amplifier that runs cool, producing startling dynamics. Internally, REL designed specially adapted home theater input filters that produce extremely flat bass down in the 20’s.

REL set out to build the loudest, relatively compact, affordable 10” unit available for pure home theater use. Critics are already lining up for reviews. The HT/1003 is designed to deliver the best bang (quite literally) for your buck when building a home theater system, featuring: crisp cabinet dimensions finished in an attractive, yet purposeful, line grained black aluminum look and topped by a 12mm thick beautifully polished top that serves to damp vibrations on the critical top surface of the cabinet.

For REL owners already enjoying the Serie T/i or S subwoofers designed for both 2-channel and theater use, the HT/1003 is designed to supplement their systems .1/LFE output to produce even higher output, adding further depth to special effects to provide a true home theater experience. If you own a REL and want theater to be wildly dramatic, add in an HT (or a few).

HT/1003 delivers a tough, honest, purpose-built appearance designed to communicate its sole mission; extremely high output home theater at bargain pricing. The cabinet’s width is minimized reducing visual mass, while depth is maximized to produce the deepest bass. REL selected tough, high-grade, horizontally oriented line-grained composite to wrap the entire cabinet. Easily handled, easily cleaned. Yet, the top surface that one’s eye sees is beautifully finished in 5 coats of hand-rubbed lacquer, creating the visual appeal they've come to be known for.
