Description
The 15LW1401 is a low frequency loudspeaker which
sets a industry standard in 15" (380 mm) high
performance transducers.
The transducer has been designed for use as a low
bass or sub-woofer component in either a more
compact reflex, bandpass or horn loaded
configuration. It provides clean, linear,
undistorted low frequency reproduction at very high
power levels, as part of a high power fullrange
system. In its reflex configuration, it can be used
in extremely compact enclosures, (65 - 130 lt) which
is ideal for touring applications, including indoor
and outdoor concert reinforcement systems.
The high excursion capabilities of the surround and
suspension system, in conjunction with the Eighteen
Sound Double Silicon Spider (DSS), enable the
15LW1401 to achieve high levels of linear travel and
maintain full control of the moving mass. The carbon
fiber reinforced, straight-sided ribbed cone assures
smooth response and exceptional strength, with
maximum reliability under high mechanical stress.
The 100 mm Ø copper voice coil 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. The weight of the
windings are evenly distributed, providing a uniform
motive drive. This, in conjunction with the use of
state-of-the-art high temperature resin adhesives,
results in an extremely linear motor assembly.
The already low distortion and sound quality of this
loudspeaker has been further improved by the Double
Demodulation Rings (DDR) designed to dramatically
reduce the intermodulation and harmonic distortion
whilst improving the transient response.
Excellent heat dissipation has been achieved by
incorporating air channels between the basket and
the top plate of the magnet. Further ventilation is
provided using air vents in the back plate that
direct air into the lower part of the voice coil
gap.
Maximum flux concentration and force factor is
assured by the unique shape and design of the top
and back plates, researched and designed using
Magnetic Flux FEA CAD resource.
The 15LW1401’s ability to perform properly under
inclement weather conditions has been achieved using
an exclusive cone treatment improving pulp strength,
which gives water repellent properties to both sides
of the cone. In addition, a special treatment has
been applied to both the top and back plates that is
far more resistant to the corrosive effects of salts
and oxidization than any other in use today. |
