Introducing SIGAO DRIVE

Posted on 23rd February 2024 in Category: News

Kudos Audio is incredibly excited to announce the development of our latest product – the SIGAO DRIVE external crossover.  

SIGAO DRIVE represents a ground-breaking new approach to crossover design, never before seen in mainstream HiFi. Neither traditionally active nor truly passive – SIGAO DRIVE is an external crossover with no power supply, situated in front of the power amplifier in the audio signal chain.

More details will be revealed in the coming weeks and months. In the meantime, here’s a brief look at what you can expect from SIGAO DRIVE.



As long-time champions of active listening, we’ve endeavoured to find a better and more efficient route to the many benefits of active configuration, by removing every non-essential component from the reproduction process. This all starts with the power supply. 

Using new, high value components and a unique PCB design with custom mechanical isolation, Kudos has produced a new kind of crossover that features no power supply, yet remains technologically capable of sitting in front of the power amplifiers in the position of a conventional active crossover. 

The sonic result has been celebrated in its name – translated from Ancient Greek, SIGAO means ‘to keep silence’. That’s exactly what SIGAO DRIVE is built to achieve – purity, accuracy, and stunning, ink black silence. In short, a whole new level of Kudos excellence.

Until now, Kudos loudspeakers in active configuration have only been compatible with a select handful of audio brands. With SIGAO DRIVE, Kudos loudspeakers are now compatible with almost any audio brand on the market. The amplifier output loading of the crossover can be adjusted to match the technical requirements of virtually any amplifier combination, meaning near-infinite compatibility with Kudos loudspeakers for the very first time. 

Derek Gilligan, Managing Director of Kudos Audio, said:

“Ultimately, our goal in creating this exciting new product is to provide the best possible experience for listening with Kudos loudspeakers. We believe that SIGAO DRIVE achieves exactly that – its masterfully simple engineering and execution reflects the very same, exacting design philosophy found in the Kudos Audio loudspeaker range. Together, they elevate one another to new heights of audio excellence.”


Previewed at the Bristol HiFi Show, the Kudos Audio SIGAO DRIVE external crossover will be officially launched at High End Munich in May and available in store during summer 2024.
