Active listening, simplified.

We wanted to find a more efficient route to the benefits of active listening – whilst removing every non-essential component from the reproduction process.

Employing our masterfully simple methodology, we’ve removed the PSU – creating an unpowered external crossover that connects directly to the power amplifiers. Utilising unique, high quality inductors (three per channel) and a custom-isolated PCB designed to acutely minimise microphonics, SIGAO DRIVE delivers a firmer grip on both the power amplifier and the loudspeaker driver than it’s conventional passive or active counterparts.

The sonic result is, simply, jaw-dropping. A dynamic, truer sound than ever experienced with Kudos loudspeakers.


Infinite Compatibility

Until now, Kudos loudspeakers in active configuration have only been compatible with a select handful of audio brands. With SIGAO DRIVE, that’s changing.

Using a carefully calculated configuration of resistors in the crossover’s outputs, SIGAO DRIVE is versatile enough to work with the full range of Kudos loudspeakers, and with almost any amplifier brand available on the market. It means SIGAO DRIVE opens up a near-infinite choice of electronics brands with any active Kudos loudspeaker you choose to use.

SIGAO DRIVE is supplied custom-fitted with the correct plugs for both your Kudos loudspeakers, and your chosen power amplifiers. And when you change your speakers or amplifiers, all you have to do is swap out the plugs.


Kudos at its best

SIGAO DRIVE is the only external crossover that’s been designed from the ground up to get the very best from Kudos loudspeakers. Its form-first, masterfully simple methodology represents the very same exacting philosophy found throughout the Kudos product line.

By ensuring the output of the amplifier is directly connected to the voice coil of the loudspeaker, the benefits of active configuration are preserved – but by removing the need for a power supply, a new level of noise reduction and sonic clarity is achieved. We believe this represents the very best way to experience Kudos – opening up a whole new level of sonic excellence.
