REL Acoustics T/5X BLACK Serie T/5x 8-Inch Powered Subwoofer in Piano Black Lacquer (Each)
The REL Acoustics T/5X BLACK Serie T/x powered subwoofer pairs a 125-watt RMS Class A/B amplifier with an 8 in FibreAlloy driver in a sealed, down-firing enclosure. Low-frequency extension reaches 32 Hz at -6 dB in-room, while high-level, low-level RCA and dedicated .1/LFE inputs support stereo and home theater connections. Recommended for rooms of approximately 75-200 square feet, this single subwoofer adds bass support without dominating the decor. Five hand-polished coats of Piano Black Lacquer and softly rounded corners give the cabinet an understated presence.
Key Features
Piano Black Lacquer and Braced Plywood Construction
The gloss-black exterior is finished by hand and shaped with softly curved edges rather than unnecessary decorative detail. Laminated plywood and internal bracing address cabinet resonance and associated distortion, so the discreet appearance is backed by purposeful acoustic construction.
8 in Long-Throw FibreAlloy Driver
The cone combines aluminum with lightweight paper, supported by a revised suspension developed for more capable, precise movement. An inverted alloy center cap and steel chassis complete the driver assembly. Together, these elements are designed to balance excursion and bass output with responsive musical reproduction.
Built-In 125-Watt RMS Class A/B Amplification
An integrated amplifier drives the active woofer, so bass amplification is already built into the cabinet. Refinements to the established Class A/B platform emphasize transparency, speed and reliable operation. Fully electronic Set Safe, DC-fault and output-short protection are also included.
Sealed Down-Firing Design and 32 Hz Extension
The active driver faces the floor, directing bass energy downward from a closed-box enclosure with no passive radiator. With in-room low-frequency extension specified at 32 Hz at -6 dB, the design adds low-end support to stereo listening and weight to movie soundtracks.
Stereo Inputs and Independent .1/LFE Control
Use the high-level Neutrik Speakon input with a conventional stereo amplifier, or the low-level RCA input for music applications such as powered speakers. A separate .1/LFE RCA path lets a home theater connection remain in place alongside the music connection, without resetting the music setup. Its independent LFE volume control lets you set the movie bass level separately, and a Neutrik Speakon cable is supplied.
Optional Arrow Wireless Integration
When a long signal cable would complicate the room layout, the compatible Arrow Wireless system offers an alternative, with hardware sold separately. Its transmission uses no digital compression and is designed for very low latency. Timing also supports a stereo arrangement with one wirelessly connected unit and one cable-connected matching unit. The subwoofer still uses its supplied AC power cord.
Recommended for Approximately 75-200 Square Feet
For apartments, bedrooms and dedicated listening rooms, the recommended room area is approximately 75-200 square feet. This configuration supplies one subwoofer. A second unit is an option for somewhat larger rooms; stereo use requires two matching subwoofers. Vertical stacking is not recommended.
