MIDRANGE 12MU/4731T00
The Illuminator midranges and midwoofers 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”!

KEY FEATURES:
Under-Hung Neodymium Motor Design
One Piece Cone-Dust Cap
Very Wide Frequency Response 100-10KHz
Patented Symmetrical Drive (SD-3)
Low-Loss Linear Suspension
High Output 90dB @ 2,83V
