Key Features & Design

• FibreAlloy™ 10" Driver: Long-throw front-firing active driver with inverted alloy dust cap for improved transient response and minimal distortion.
• Down-firing 10" Passive Radiator: Enhanced low-frequency extension (–6dB at 27Hz) in a surprisingly compact footprint (370×340×393mm).
• Class A/B Amplifier: 300W RMS power with high current reserves and robust power supply for slam, authority and reliability.
• High-Level Neutrik Speakon Input: Retains tonal integrity and musical timing when partnered with your main amplifier.
• Optional Arrow™ Wireless: Zero-compression, low-latency link—no sonic compromise and no messy cables.
• Elegant Cabinet: Rounded corner radii and high gloss finish in Black or White—fits seamlessly into modern listening rooms.

Performance & Sound Quality

The T/9x doesn’t just reproduce bass notes; it breathes life into them. Its FibreAlloy™ cone offers agile transient response, so complex passages remain tight. The proprietary suspension delivers a controlled, musical delivery with no bloat—even at high output levels. When tracking orchestral scores or explosive action sequences, the T/9x dives deep to 27Hz, granting authentic subterranean rumble without sacrificing speed or detail.

Coupling the subwoofer via high-level inputs unlocks another dimension: a natural tonal balance and seamless integration with your main speakers. Entries in piano pianissimo passages emerge with delicate nuance, while rock bass guitars hit with rock-solid punch. We also tested the Arrow™ wireless module—instant set-up and unerring timing ensure the sub stays in perfect sync.
