Spec Sheet PDF

The Illuminator woofers are in every aspect unusual designs with the open construction, the extremely long linear excursion and patented under-hung SD-3 (Symmetrical Drive) neodymium motor system, which due to copper caps and its construction ensures very low distortion, adding the unique patented cones, low-loss linear suspension the result is: ”The Very Best Money Can Buy”!

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.

• Underhung motor system
• Exceptionally long linear stroke
• Black Anodized Aluminium Cone 
• Patented symmetrical drive motor system
• Neodymium magnet
• Voice coil gap fully encapsulated with copper caps
• Optimized for woofer application in 3-way systems
