Illuminator 12MU/4731T00 by Scanspeak Description
The Illuminator 12MU/4731T00 from Scanspeak is a 4" (10cm) midrange driver that stands out due to its unique features. Built in an open design, it offers an extremely large linear excursion and a patented underhung voice coil system SD-3 with neodymium drive. These features result in very low distortion and, combined with the patented cone, ensure a lossless linear excursion. Furthermore, the midrange driver has a very wide frequency range and high efficiency. In short: Here you get high quality for your money.
