Speaker 18 Sound 12LW800, 8 ohm, 12 inch

The 12LW800 is a low frequency loudspeaker which sets a new industry standard in 12" (300mm) Ø high performance transducers, achieving a remarkable 42Hz downwards extension with 96dB average sensitivity and handling peak power levels of 4000W with remarkably low distortion and excellent transient response.

The 12LW800 is intended as the low bass or sub-woofer component, either in highly compact reflex, bandpass or horn loaded configurations, in which it provides clean, linear frequency reproduction at high power levels, or as part of a compact high power fullrange system. In its reflex configuration, it can be used in extremely compact enclosures (40 - 70lt) making it ideal for portable applications such as road shows and bass musical instruments, for “wedge" stage monitors, etc.
The high excursion capabilities of the double-action roll surround and suspension system, in conjunction with the Double Silicon Spider (DSS), enable the 12LW800 to achieve very high levels of linear travel for a 12" unit.
With its custom design surround, the carbon fiber reinforced curvilinear ribbed cone assures smooth response and exceptional strength with maximum reliability under high mechanical stress. The 75 mm state-of-the-art voice coil employs the Interleaved Sandwich Voice coil (ISV), in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil and providing a uniform motive drive.
This, in conjunction with the use of unique high temperature resin adhesives, results in an extremely linear motor assembly with reduced tendency to break-up under hard drive conditions. Excellent heat dissipation is achieved incorporating air channels between the basket and the top plate.
Maximum flux concentration and force factor in the gap are assured by the unique shape and design of the face and back plates, which have been designed using our in-house Magnetic Flux FEA CAD resource.
The ability to perform properly under inclement weather conditions is an essential point of the Eighteen Sound philosophy. These features are obtained through an exclusive cone treatment improving pulp strength and giving water repellent properties to the cone. In addition, a special treatment applied to both the face and back plates allows the product to be far more resistant to the corrosive effects of salts and oxidization than any other treatment in use.
