The 15W1200 is a low frequency loudspeaker which sets a new industry standard in 15" (380 mm) high output transducers. The 15W1200 is intended as the low bass either in a reflex or horn loaded configuration, in high power fixed or touring loudspeaker systems. It provides clean, linear, undistorted low frequency reproduction at very high power levels.
In its reflex option it's also suited to bass instrument applications - especially 5-string fretless bass guitar.
The high excursion capabilities of the surround and suspension system, in conjunction with the Eighteen Sound Double Silicon Spider (DSS) technology, enable the 15W1200 to achieve high levels of linear travel and maintain full control of the moving mass.
The 15W1200 is fitted with a low profile, carbon fiber reinforced, smooth curvilinear cone carried by a triple roll, polycotton suspension and double silicon spider assembly.
The state-of-the-art voice coil employs our own 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 balanced coil with a uniform distribution of mass and motive energy. This results in an extremely linear motor assembly.
The excellent performance capabilities of this loudspeaker have been further enhanced using Double Demodulating Rings (DDR) designed to dramatically reduce the intermodulation and harmonic distortion and improve the transient response.
Heat dissipation has been achieved by incorporating air channels between the basket and the magnetic top plate. Further ventilation is provided using air vents in the back plate that direct air into the lower part of the voice coil gap.
The magnetic structure has been optimized using FEA CAD resource to maximize the flux density within the voice coil gap.
An exclusive cone treatment process designed to improve the pulp strength and provide water repellent properties is applied to both sides of the cone. This, in conjunction with the special anti-corrosion treatment given to both the top and back plates, enables the 15W1200 to be used outdoors and in marine environments.
