The Scan-Speak Classic 18W/0-00-00 isn't a typical speaker driver, but a passive radiator. This means it doesn't have its own voice coil and doesn't generate sound directly. Instead, it's designed to work in conjunction with a specific Scan-Speak woofer (likely from the Discovery Series) to enhance the bass response of your speaker system.
By vibrating sympathetically with the woofer's movements, the passive radiator extends the perceived low-frequency output, creating a richer and deeper bass experience. This can be particularly beneficial in situations where a larger woofer enclosure might not be feasible. Additionally, passive radiators can sometimes help achieve tighter and more controlled bass compared to using a larger woofer alone.
Remember, for optimal performance and to avoid potential damage, it's crucial to use the 18W/0-00-00 with the specifically recommended Scan-Speak woofer. Contacting Scan-Speak customer support is the best way to confirm compatibility and find authorized retailers for both the passive radiator and the compatible woofer.
