Product details

Scan-Speak Illuminator 18WU/4747T00 7" Woofer

 

Illuminator woofers are based on compact under-hung motor systems with large neodymium ring magnets. The patent pending motor offers a very long linear excursion together with a very high force factor. The top plate is shaped to “guide” the backside airflow around the motor and with the very open cast aluminum chassis design the driver is virtually free from compression.
