The highly anticipated Kii Audio BXT bass extension modules for the Kii THREE active loudspeaker system are finally available in Australia.

First announced in 2015, Kii Audio disrupted the loudspeaker industry with its small footprint loudspeaker that is far more than meets the eye.

Each Kii THREE contains six channels of DSP, D/A conversion and N-Core power amplification. According to the company, “the AD/DA circuitry of the THREE's signal processing board is entirely inaudible, a feat not duplicated by the most expensive audiophile standalone units”.

The DSP is responsible for keeping the drive units within their safe operating range by gently adapting the filters instead of brutally limiting the signal. This allows the THREE to play significantly louder and cleaner than much bigger traditional designs.

While the Kii THREE achieves so much for its size, many yearned for matching subwoofers for more bass reinforcement. Kii Audio delivered with the announcement of the BXT modules specifically designed to sit beneath the Kii THREE.


While the demand far outstripped the company's ability to supply, the good news is you don't need to wait any longer.

The add-on BXT module replaces the THREE's speaker stands and transforms the compact speaker into a full size and formidable floor standing system, adding an additional 16 woofers mated to 7000w of amplification.

The effect of the BXT expansion module is pronounced and must be heard to be believed. This significant upgrade to the THREE creates a full range system that effortlessly energises even the largest of listening rooms with deep and incredibly fast and accurate bass.

Kii THREE, particularly when combined with BXT, makes for a 21st-century hi-fi system that every audiophile and music lover should experience.

A range of listening events are currently being scheduled around the country, the first of which will be this Saturday 29th June at Sonic Purity Showroom, 30 Bignell Road, Moorabbin, Melbourne between 10am-5pm.

Kii THREE and Kii CONTROL are available for $22,700 RRP, while the newly available Kii BXT sells for $28,000 RRP.
