  • The HT-1205

    Serie HT is designed specifically to answer the challenge of creating affordably priced, exceptionally dynamic, pure home theater powered subwoofers. The HT/1205 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.

    Bring on the special effects

    HT/1205 delivers a tough, simple, purpose-built appearance designed to communicate its sole mission; devastatingly high output home theater. The cabinet’s width is minimized reducing visual mass, whilst depth is maximized to produce the deepest bass. We selected tough, high-grade, horizontally oriented line-grained composite to wrap the entire cabinet, which offers easily handled, easy cleaning. This more basic design vocabulary differs from the more refined finishes found in our other lines, however the top surface that catches one’s eye is beautifully finished in 5 coats of hand rubbed lacquer, creating the visual appeal we’ve come to be known for.

    Twelve-Inch CarbonGlas™ Driver

    REL’s driver prowess is on full display with the HT/1205, a modern 12” CarbonGlas™ (300mm) driver that is both lightweight and extremely stiff. While many competitors drone along with relatively slow, heavy cones HT/1205’s uses tough, stiff carbon fibre over 60% of the driven surface, backed by lightweight glasfibre. Naturally, we use true high quality natural butyl surrounds as they remain soft and pliable for decades—something REL owners have come to expect. HT/1205’s new 12” CarbonGlas driver sets a new standard for affordable, high performance theater-specific drivers.
