Cabinet Enclosures
15mm, (5/8”) plywood is used in the construction
of cabinet enclosures on all models. The use of
solid glue joints and the critical placement of
internal bracing results in enclosures that vir-
tually indestructible as well as resonance-free.
Shape: Maximum Versatility
The Asymmetrical trapezoidal design shape with a
45° angle provides for Stage Monitor use and
Front of House applications (PW10-PW12-PW15).
Finish
Durable textured black paint is used to with-
stand to the rigors of the road when transpor-
ting and provide a stylish appearance for perma-
nent installations.
Pole Mount Sockets & Handles
For speaker stand mounting, all PW models are
equipped with a 35mm
Ø (13/8”) aluminium pole
mount socket.
Ergonomically placed
integrated handles are
built into the 100%
plywood structure of
the cabinet enclosure.
Heavy Duty Grilles
An extremely rugged
1.2mm (0.05”) steel
grille with high apertu-
re ratio protects the
speakers without
detracting from their
sonic performance in
any way.
Rigging / Fly Points
All Kempton PW enclo-
sures are provided
with multiple M10 fly
points (M6 on PW10)
to accept standard
eye bolts and facilitate safe and easy flying capa-
bilities.
Connectors
All Kempton PW model Speakers feature profes-
sional 2 x 4-pin Speakon connectors that are
mounted to a recessed panel to prevent inadver-
tent operation.
Components
All components were carefully selected and
manufactured to Kempton’s specifications and
tolerances and then severely tested for reliability
for the Kempton PW Speaker series. The custom
designed Woofers feature high strength curvili-
near cones on die cast frames, high temperatu-
re resistant voice coils to prevent burnout failu-
res and ferrite magnet structures to produce
solid low frequency response. The HF compres-
sion drivers provide clean and clear high fre-
quency output and are coupled to an 80°H x 50°V
custom designed constant directivity horn for
precise dispersion.
Crossover Networks
The Heavy Duty Crossover Networks that divide
the signal going to the woofer and compression
driver are constructed with oversize coils, high
voltage capacitors and power resistors to provi-
de the best possible sound quality and minimize
signal loss. Independent LF and HF overload pro-
tection circuits are employed to protect the woo-
fers and HF drivers from failures.
