CETE / Milltek Active Valve Control Module

CETE Automotive develops electronic solutions for controlling a vehicle’s active sound system. Its product family includes Active Sound Gateway modules and the later Active Sound Unit.

A dedicated app configures and controls compatible sound booster systems. CETE products personalise the soundtrack rather than acting as a conventional exhaust system, so the correct module must be selected for the vehicle’s equipment.

Active Sound Unit brings different sound files together in one module instead of tying the soundtrack to one controller’s characteristics. It evolved from the earlier Active Sound Gateway. The product family also includes Gateway versions with Wi-Fi and BLE connectivity, making it important to match the hardware generation with the appropriate app.

History and development. CETE’s roots lie in development of the Alex-Modul in 2012. The company was established in 2013, with the device renamed Active Sound Gateway. Successive generations expanded sound-control functions, and Active Suspension Control BLE joined the range in 2017.

The business today. CETE now develops electronics for active sound and suspension control. The Active Sound Unit and its companion app illustrate the transition from one module to a broader product platform. Its electronic solutions complement mechanical vehicle modifications rather than replacing them with a complete exhaust system.
