Illuminator 12MU 8731T00 Diameter:120mm

Paper Cone Midrange

The Illuminator midrange units utilise Scanspeak's patent design paper cone and compact under-hung Neodymium magnet system, producing a unit that offers a long linear excursion and very high force factor. This unit has a very wide frequency response range from 100Hz upto 10,000Hz.

The uniquely designed front flange is shaped to guide the airflow around the rear of the unit and along with the open diecast aluminium chassis, helps to produce a unit that is virtually compression free.
