Description

The 15W700 low frequency transducer meets the specific market demand
for a loudspeaker which combines good linearity and efficiency with
high power handling capabilities, containing a 75 mm ? aluminum voice
coil.
Although
primarily intended for use in tuned reflex enclosures, the versatile
characteristics of the 15W700 render it suitable for a wide variety of
enclosure types, particularly as a subwoofer or as a LF driver in 2 or
3-way systems. When used in a 2-way system, we recommend a 1.4″ or 2″
exit compression driver in order to obtain the best sound quality.
The
deep profile curvilinear paper cone has been made using a special high
strength wood pulp and designed to achieve the best possible linearity
within its intended frequency range and to control bell-mode resonances
around the cone circumference. The cone is carried by an unusually deep
profile, double half-roll suspension formed of a linen-like material
which is more resistant to aging and fatigue than the traditional
cotton-based materials used in conventional surrounds.
The 75 mm ?
aluminum 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.
This results in an extremely linear motor assembly with a reduced
tendency for eccentric behavior when driven hard.
The magnetic
structure has been optimized using our in-house FEA CAD resource that
has maximized the flux density in the voice coil gap. Excellent heat
dissipation has also been achieved by incorporating air channels
between the basket and the magnetic top plate.
Due to the increase
in use of audio systems at outdoor events, the ability of the 15W700 to
perform in adverse weather conditions or in areas of high humidity is a
great advantage. This has been achieved using exclusive treatments
which enable the cone and the magnetic plate to resist corrosion and
render the cone water repellent at the same time.
