Synopsis
Selenium's 12MB3P was developed to excel at midbass sound reproduction in professional speaker systems. It provides high output with low distortion when used in vented, sealed, or horn-loaded applications. The 12MB3P features high power handling, great efficiency, and rugged reliability, while its smooth, extended response facilitates the choice of driver cutoff frequencies. Its 3" voice coil is wound with flat aluminum wire on a polyimide former, and the moving parts are housed in a low profile injected-aluminum chassis.
