The 12W500 is a 500W program low frequency driver designed to satisfy the need for a 12" loudspeaker which combines excellent linearity with good sensitivity and power handling characteristics. It is primarily intended for compact bass reflex applications in enclosures as small as 50 lt, typically for two-way systems in combination with 1" compression driver.
50 lt, typically for two-way systems in combination with 1" compression driver.
The high quality paper cone has a smooth, curvilinear profile design that eliminates bell-mode resonances within the intended frequency range.
This is carried by a specially treated, dampened double half-roll linen suspension which has been designed to control excursion maintaining the piston action linearity.
The 12W500 employs the 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.
Voice coil cooling is achieved by incorporating airways between the chassis back plate and the top plate of the magnet, allowing heated air from the voice coil and gap to be channeled away and dissipated by the chassis basket.
