Active Subwoofer REL Acoustics T/9x (White)

Active Subwoofer REL Acoustics T/9x (White) is the flagship of the T/x series and the most powerful model in the range, combining dynamic power with refined acoustic precision. Its deep, rich bass and impressive response speed make the T/9x the perfect choice for large rooms, high-end stereo systems, and home theaters where you need big sound without losing control. This model features a 254 mm active driver located on the front panel and a passive radiator of the same size directed downward. Both are equipped with lightweight long-throw cones with aluminum dust caps and steel baskets, providing a combination of bass depth, instant response, and structural rigidity. The T/9x's frequency response extends to 27 Hz at -6 dB, allowing it to reproduce the lowest frequencies with accuracy and volume.

Power is provided by a 300 W RMS Class AB amplifier, ensuring stability and control even at high volume levels. The subwoofer is equipped with high-level Neutrik Speakon inputs, as well as RCA (line and LFE). Wireless connection is supported via the REL Arrow system (optional), eliminating the need for cabling.

The T/9x has an elegant lacquer finish, five-layer coating, and rounded corners. The model is also equipped with REL's proprietary SET-SAFE protection system and is stabilized for operation in all conditions.
