Scanspeak 12MU/4731T00 Midrange - Illuminator Range
Scanspeak 12MU/4731T00 Illuminator Midrange Unit - a radical rethink in drive unit design.
This 12cm Illuminator midrange unit is the culmination of many years research. Features include a cutting edge open chassis with airflow optimisation and an underhung Neodymium magnet system that is outrigged from the chassis - the combination of these advancements define new standards in terms of minimal compression & reflection.
With a text book response curve and extraordinary bandwidth of 100Hz-10KHz, this audiophile drive unit is an ultimate choice for high end 3 way systems and represents the very pinnacle of transparency and sound quality.
