Flagship Serie T/x subwoofer • 10" active driver & 10" down-firing passive radiator • 300W Class A/B power amplifier • high-level Neutrik Speakon connection • high-gloss lacquer finish
The REL Acoustics T/9x stands as the flagship model in the acclaimed Serie T/x lineup, delivering legendary REL speed, physical impact, and musicality in a beautifully proportioned cabinet. By pairing a front-firing 10-inch FibreAlloy driver with a down-firing 10-inch passive radiator and a high-current 300W Class A/B amplifier, it seamlessly blends deep sub-bass extension into two-channel stereo systems and high-end home cinema setups alike.
Key Features & Innovations
Flagship Serie T/x performance — the REL Acoustics T/9x combines an active long-throw 10-inch driver with a matching 10-inch passive radiator to produce greater output and deeper low-frequency extension without losing transient speed.
Signature high-level Neutrik Speakon input — connects directly to your main amplifier's speaker output terminals, allowing the subwoofer to receive the exact sonic character and timing of your main power amp.
300W linear Class A/B power amplifier — high-current MOSFET amplifier design built for sustained power delivery, exceptional control, and rapid dynamic response during demanding musical passages.
Lightweight FibreAlloy driver technology — continuous-dustcap aluminum and cap paper driver cones reduce moving mass while increasing rigidity for ultra-fast, articulate bass response.
What is the advantage of using REL's High-Level connection?
Connecting the REL Acoustics T/9x via the included High-Level Neutrik Speakon cable allows the subwoofer to sample the identical sonic signature, tonal balance, and timing of your main amplifier for seamless speaker integration.
Can I use the T/9x for both stereo music and home theater LFE?
Yes. REL subwoofers feature independent volume controls for High-Level (music) and Low-Level/1.2 LFE (home theater) inputs, allowing both inputs to be connected simultaneously for seamless transition between music and movie sources.
Does the T/9x support wireless connectivity?
Yes. The T/9x is compatible with REL's optional Arrow wireless system, providing zero-compression high-level or LFE wireless signal transmission without running cables across your room.
Is a sealed or passive-radiator design better for music?
REL’s engineered passive radiator system acts as a sealed enclosure down to its tuning frequency, providing the lightning-fast transient response required for music alongside the added output headroom of a ported design.
