Scanspeak Illuminator15WU 4741T00

Paper Cone Mid/Bass

The

Illuminator

mid/bass 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. 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.
