History of an Australian Icon

The first Maestro series loudspeaker was completed in 2004. Called the MT3F, it was characterised by its bulky trapezoidal bass cabinet with dual custom-made 10” paper cone woofers; drawing universal praise from local audio enthusiasts who had previously never experienced the sonic revelation of a critically-damped sealed cabinet capable of flat extension to 20 Hz.

As word filtered throughout Australia, the number of proud owners slowly increased while development continued in the background. In 2009, we released the MT3FSL, a “slim line” version of the MT3F with a more advanced cabinet and a single 10” bass driver. This was also the first Maestro series model to incorporate the electronics within the speaker cabinet and to offer a myriad of advanced adjustments on the back of the electronic active technology.

The ongoing quest for perfection eventually led to the debut of the MT3.2 at the 2013 Consumer Electronics Show in Las Vegas. This product combines the ultimate sense of scale and power of the original MT3F model with the smaller footprint, adjustability, and aesthetically pleasing proportions of the MT3FSL.

Built on a strong foundation

Designed with strong electronic and acoustic engineering principles, through countless simulations, measurements and computer optimisations, the MT3.2 represents the pinnacle of our loudspeaker efforts and the evolution of 10 years research into transducer design.

Bass quality is critical in a high-performance audio system, as it is the bass that provides the rhythmic and harmonic foundation. The bass carries the music and binds everything together. Get the bass wrong, and the music will sound wrong.

Instead of following the market trend towards increasingly more rigid cone materials in an attempt to push resonances out of the audible band, we addressed the problem in the time domain using our proprietary paper cone formulation which has a higher stiffness to damping ratio than all known woofers. The result is a purpose built woofer with stored energy dissipation which rivals some of the very best tweeters! Never before has bass sounded this fast and articulate.
