SKU: HT1003 Category:


REL’s home theatre-focused Serie HT line is designed specifically to answer the challenge of affordably priced, highly dynamic pure home theatre 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 theatre input filters that produce extremely flat bass down in the 20’s.

The HT/1003 is designed to deliver the best bang (quite literally) for your buck when building a home theatre system, featuring: crisp cabinet dimensions finished in an attractive, yet purposeful, line grained black aluminium-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 Serie T/i or S subwoofers designed for both 2-channel and theatre use, the HT/1003 is designed to supplement their system’s .1/LFE output to produce even higher output, adding further depth to special effects to provide a true home theatre experience. If you own a REL and want theatre to be wildly dramatic, add in an HT (or a few).

Critic Reviews


“Although the HT/1003 is a departure from purist REL
philosophy, the result is an outstanding-value home cinema subwoofer. For AVR owners after a compact, affordable bass box that delivers movie mayhem in spades, look no further.” Click for full review.
