Punch Audiophile Woofer manual

INTRODUCTION

This manual provides information on the construction, installation
and operation of the Punch Audiophile Woofers. We suggest you save
this manual for future reference.

The Punch Audiophile woofers are a full line of low frequency drivers
in 8", 10", and 12" sizes; in 4 or 8 ohm impedance. They are designed
for use primarily in small, sealed enclosures. By utilizing the latest
materials and construction techniques, we are able to offer a speaker
with good, low frequency response while requiring a minimum of
operating space.

DESIGN FEATURES

Cone – The cone material used is spruce pulp paper reinforced with

Kevlar® fiber (8" and 10" only). This provides the necessary combi­nation of weight and strength and allows high levels of output without
cone break up. The cone is treated with a water resistant Polyvinyl
Acetate Emulsion (PVA) which increases the cone rigidity and lowers
distortion.

Vented Pole Piece – To allow operation at reasonably high power
levels, ventilation is needed. This is done through the use of a vented
pole piece. The venting allows fresh air to circulate and remove the
built up heat from the voice coil assembly.

Suspension – The suspension holds the cone to the basket and
supports the voice coil in the magnetic gap. The suspension should
allow the cone to move in and out freely but not allow side to side
motion. The Punch Audiophile woofers all use a Nitrile rubber
surround for the front and a flat spider design for the rear. This
combination takes full advantage of the Kevlar® cone's stiffness
allowing clean, uncolored reproduction.
