18s 12LW800 8 Ohm

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, 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, to provide 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 ideally suited to 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 Eighteen Sound Double Silicon Spider (DSS), has enabled the 12LW800 to
achieve very high levels of linear travel for a 12" unit.
The carbon fibre reinforced curvilinear ribbed cone, with its custom design surround, assures smooth
response and exceptional strength with maximum reliability under high mechanical stress.
The 75mm Ø state-of-the-art voice coil is similar to that fitted to our 18LW1400 top-of-the-range
model. It employs our 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 high drive
conditions.
Excellent heat dissipation is achieved by the incorporation of air channels between the basket and
top plate.
Maximum flux concentration and force factor in the gap is assured by the unique shape and design
of the face and back plates, these having been researched and designed using our in-house
Magnetic Flux FEA CAD resource.
With the increasing use of high power audio systems at outdoor events or in a marine environment,
the ability to perform properly under inclement weather conditions is another part of the Eighteen
Sound philosophy. This is achieved by means of an exclusive cone treatment improving pulp strength
and giving water repellent properties to the
cone. In addition, special treatment of both the face and back plates results in a product which is far
more resistant to the corrosive effects of salts and oxidisation than any other treatment in use.
