- Ideal for compact two way systems
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. 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.
