Scanspeak 12MU/8731T00 Midrange - Illuminator Range

12MU/8731T00

12cm 8 Ohm Audiophile quality midrange unit. 

Illuminator logo

This Illuminator midrange is a highly advanced drive unit featuring some very forward thinking technology. The unique alloy chassis is open and has been optimised for maximum airflow with minimum reflection / sound disturbance; the underhung magnet is outrigged from the chassis;  the spider is completely open on both sides and the patented pulp cone / dust cap is a one piece jointless design. These advancements result in an very open, natural sound with minimal compression.

With a text book response curve and an excellent bandwidth of 100Hz-10KHz, these exotic drive units have realism / transparency and are a top choice for high end 3 way designs.

This is the 8 Ohm version - 4 Ohm version here: 12MU/4731T00
