We embarked on an intense journey to develop new components that achieved the strongest combination of output, power handling and control but also strived to specifically reduce 3rd harmonic distortion in all designs.

Our goal was based on the audibility limits of odd and even harmonics. Generally speaking we can only hear distortion levels of even harmonics when they reach levels of 1% -2%, but we can hear distortion levels as low as 0.1% in the odd harmonics of a signal. If you could drop 3rd harmonic distortion from 1% to 0.1% in a transducer, you could increase the true dynamic range dramatically.

The effort was incredibly fruitful, resulting in new, very low distortion components for our cabinets that represent the cutting edge of transducer design from our specific application approach.

One of the most challenging projects undertaken by the team was the development of our new NVPD range of compression drivers. The idea came during an

Italian lunch, where we discussed a new nitrate coating used in Formula One racing, offering extreme strength and rigidity. Extremely light, it is great for cars but never before tried in Pro Audio.

Our original ES and EX designs had produced a 1” compression driver which in its class boasted the lowest distortion figure of any 1”driver in the world, so improving on that was going to be a challenge.

By treating the diaphragm with a Nitrate Vapour Particle Deposition (NVPD) process the dome’s resonance and dampening characteristics dramatically improved, lowering distortion even further and extending frequency response. By adding some of the largest Neodymium motors available today and our advanced phase plug design the result was a range of world beating high frequency units that produce distortion of less than 0.03% and measure flat up to 22kHz, continuing to extend beyond 35kHz.

For improved midrange clarity
and output we implemented a Trans Coil technology that eliminates voice coil inductance, called AIC (Active Impedance Control). This results in a flat impedance response above the resonance point making it much easier for the amplifier to control. In a two way box the speaker behaves like a woofer at low frequencies and a mid-range device at higher frequencies. In a midrange role its phase coherence, efficiency and low distortion allow for the purest and most natural sounding vocal reproduction with incredibly fast dynamics and transient response.

Our new and forthright technologies provide the building blocks for systems that are developed to challenge the very existence of other products exhibiting higher distortion and lower acoustic output.
