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 amplifiers in the audio signal chain.

As long time champions of active listening, Kudos 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 quality 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 purity, accuracy, and stunning, ink black silence.

Designed specifically to work with Kudos Titan speakers (808, 707, 606 and 505), putting them in an active configuration making them compatible with virtually any electronics brand for the very first time and opening up a whole world of new system upgrade opportunities.

Impedance matched to your choice of amplifier.

Being unpowered, the Kudos Sigao Drive crossover has no active electronics or power supply to add their inherent character to the sound, and thus the invasive components are eliminated.

Kudos use an enclosure with a carefully selected mass to control resonance, machined from a solid billet of aluminium. This helps shield the internal assemblies from external acoustic, mechanical and electrical disturbances. The PCB is decoupled from the enclosure using a purpose-designed PCB mechanical decoupling system. Compound dual isolation from residual vibrations provides the filter components with the best operating environment to maximise SIGAO DRIVE’s performance.

A 4-layer PCB is specified and designed to minimise susceptibility to external electrical fields while not increasing the signal path capacitance unduly. Filter inductors are custom manufactured to Kudos specification and built to a very tight, exacting tolerance. Kudos opted for capacitors using polystyrene dielectric, considered by Kudos Audio to be the best sounding in its crossover filters.

Until now, Kudos loudspeakers in active configuration have only been compatible with a select handful of audio brands (Linn Exakt, Naim Snaxo, Exposure etc). 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 active Kudos loudspeakers for the very first time.  

SIGAO DRIVE represents the very best way to listen with Kudos, whilst elevating The Kudos Difference to a whole new pinnacle of sonic excellence.
