About the REL HT1205 MKII

A sparkling new amp design that effortlessly delivers 500W into an all-new CarbonGlas™ 12” (300mm) driver. The sexy new black lacquer top plate has a subtle REL logo floating on top, while the expensively wrought black line-grained composite for the cabinet looks the business.

HT/1205 MKII plays 50% louder than its predecessor, while also delivering more precision and subtlety. It is capable of output levels more commonly found in models well over $1,000/£1,000. Fantastic for music and available HT-Air rounds out a perfect offering.


Serie HT is designed specifically to answer the challenge of creating affordably priced, exceptionally dynamic, pure home theater powered subwoofers. The HT/1205 MKII is the ideal combination of a lightweight, modern 12” CarbonGlas™ (300mm) driver coupled to a powerful 500W Class D amplifier that runs cool, producing extraordinary dynamics. Internally, we developed specially adapted home theater input filters that produce extremely flat bass down in the 20’s.

We set out to build the loudest, relatively compact 12” unit available for pure home theater use, and at truly attractive pricing. You’ll be the judge of how well we accomplished that goal, but critics are already lining up for reviews. We believe the HT/1205 MKII is destined to become a modern classic with svelte 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 our Reference, Serie S and T/i subwoofers designed for both 2-channel and theater use, the HT/1205 MKII is designed to supplement their system’s .1/LFE output to produce extremely high output for chest rumbling home theater special effects.
