- The 12MB700 is a very high sensitivity 101.5 dB 1W/1m midbass driver with high power handling capabilities. The 12MB700 can be used as either a bass/mid driver in compact 2-way reflex enclosures or as a direct radiating or horn loaded, dedicated midrange driver in multi-way touring & fixed installation concert & arena systems. Its curvilinear paper cone made from a special high strength wood pulp has been designed to achieve the best possible linearity within its intended frequency range.
- The 75 mm diameter state-of-the-art voice coil is similiar to those fitted to our top-of-the-range 18″ and 15″ models but it is wound with aluminum wire. It employs our Interleaved Sandwich Voice coil ISV technology in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil. This results in an extremely linear motor assembly with a reduced tendency for eccentric behavior when driven hard.
