Scan-Speak Illuminator 7" Paper Cone Woofer 18WU/8741T-00
Under hung voice coil
Neodymium magnet
Exceptionally long linear excursion
paper cone
8 ohm
The 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.
