REL T/9x Subwoofer

The REL Acoustics Series T/9x Subwoofer brings together a front-firing active 10-inch FibreAlloy driver, a down-firing 10-inch passive radiator, and a 300-watt Class A/B amplifier. That combination gives you deep bass support for music and home theater while keeping the cabinet size approachable for rooms that need real low-end extension without moving into a much larger enclosure.

High-Level Input connection is part of the design, along with Low-Level RCA and LFE RCA inputs. That gives you flexible hookup options, including the ability to connect through your amplifier’s speaker outputs when that is the right fit for your system. The T/9x also uses a fast-filtered design and REL’s suspension tuning approach, which means the subwoofer is built around speed, control, and integration with the rest of your speakers.

The 10-inch active driver uses an inverted alloy dust cap and steel chassis, while the passive radiator helps support output from the enclosure. Low-frequency extension is rated to -6dB at 27 Hz, and the cabinet measures 14.5 x 13.4 x 15.5 in. / 370 x 340 x 393 mm, with a net weight of 45.5 lbs. / 20.6 kg. Gloss Black, Gloss White, and Gloss Grey finish options let you match the subwoofer to your room.

If you want a serious subwoofer for stereo listening, movie nights, or a full-range home theater setup, the T/9x gives you a clear path to adding bass with flexible connection options and a clean, understated look.
