REL Acoustics T/9X WHITE Serie T/9x 10-Inch Powered Subwoofer in White (Each)
The REL Acoustics T/9X WHITE Serie T/x powered subwoofer combines 300 watts RMS of built-in Class A/B amplification with a 10 in. front-firing FibreAlloy driver and a 10 in. down-firing passive radiator. In-room low-frequency extension reaches 27 Hz at -6 dB, while high-level Neutrik Speakon, low-level RCA and dedicated LFE RCA inputs support stereo music and home theater integration. Finished in five coats of Gloss White Lacquer, this single subwoofer is designed to complement floorstanding speakers, stand-mounted monitors and smaller panel speakers.
Key Features
Gloss White Lacquer and Rounded Cabinet Design
Rounded corners reduce perceived bulk while accommodating a larger internal volume. The five-coat lacquer finish gives the enclosure a glossy white exterior, making its appearance part of the presentation in a visible listening space.
FibreAlloy Driver and Passive Radiator
A lightweight FibreAlloy cone and aluminum center cap support transient response, while revised suspension and reduced enclosure back pressure aid efficiency and control. The forward-facing active driver works alongside a downward-facing passive radiator; both use long-throw designs with inverted alloy center caps and steel chassis. In-room bass extension is specified at -6 dB at 27 Hz.
300 Watts RMS of Class A/B Amplification
The amplifier platform incorporates revised MOSFET drivers and transformer mounting. Filtering, tuning and limiting work with the high-level connection to help integrate the subwoofer with the main speakers, supporting a system built for music as well as movie soundtracks.
High-Level, Low-Level and LFE Connections
Choose a Neutrik Speakon high-level input, low-level RCA input or dedicated LFE RCA connection to match your system's signal path. A Speakon cable and AC power cord are supplied for a high-level setup; plan for a separate interconnect when using RCA. The crossover spans 20-120 Hz, providing a defined tuning range for blending bass with your main speakers.
Optional Arrow Wireless
Arrow carries the audio signal without digital compression, offering an alternative to a wired signal connection. The wireless equipment is sold separately, and the subwoofer still requires AC power. A stereo pair requires a second matching subwoofer; one unit can be wired while the other uses Arrow.
Room Guidance for Music and Home Theater
REL Acoustics recommends rooms of 150-400 square feet for this single-subwoofer configuration. As the flagship of the Serie T/x range, it serves two-channel listening and home theater, giving shoppers with both priorities one powered bass component to integrate into their system.
