Aluminium Cone Mid/Bass
This Illuminator mid/bass unit utilises Scanspeak's patent anodised aluminium cone and compact under-hung Neodymium magnet system, producing a unit that offers an exceptionally 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.
