Key Features

  • Front-firing 8-inch driver paired with down-firing 10-inch passive driver
  • Signature series T/x Class A/B amplifiers with 200-watt power for superior sound
  • Zero compression wireless connection with optional Arrow Wireless system
  • High-level Neutrik Speakon input cable (10 m or 33 ft.) for retaining the quality of input from speaker
  • High-quality construction with a compact footprint and branded accents
  • As low as -6 dB output at 30 Hz 

This REL subwoofer from the T/x Series has two drivers essentially, an active front-firing one and a passive down-firing one. They have used the same Class A/B amplifiers that they have been using for over a decade now. So, in terms of power and frequency range, the Tx/9 is simply unbeatable. 

It uses the signature high-level input connection that ensures that the same signal goes to the subwoofer that’s going into the speaker. The amplifier doesn’t draw power from the amplifier of the speaker. As a result, the sound is truly high-quality. That said, you have the traditional RCA input option and the LFE/.1 input better suited for home theater systems

The optional Arrow Wireless system can provide wireless connection without losing to digital compression. So should you want no cables, adding this connectivity option can further improve the experience.
