INTRODUCTION

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

The Punch Power Woofers incorporate the best available materials in
an innovative design that achieves solid low frequency performance
at high levels with outstanding power handling. From the oversized
magnet for high motor efficiency to the low resonant cast aluminum
basket no detail has been overlooked in designing the finest low
frequency speaker available. The materials and construction tech­niques which make this possible are listed below.

DESIGN FEATURES

Cast Aluminum Basket – The basket is the supporting structure for the
speaker and must not vibrate or flex with the speaker's operation. The
low resonant cast aluminum basket used on the Punch Power
Woofers is strong enough to support the large magnet assembly and
will allow the speaker to operate at low frequencies without sonic
coloration.

Oversized Magnet – Oversized magnets are used for high efficiency
and improved power handling. The magnet is protected by an
attractive rubber cover which can be oriented to match the system
layout.

Binding Post Terminals – The amplifier connects to the speaker
through the use of gold-plated 5-way binding posts. These binding
posts are versatile connectors which allow for the connection of the
speakers with a variety of different terminals such as banana plugs or
spade lugs. The binding post will also accept bare wire up to 12 gauge
and are spaced on 3/4" centers to accommodate dual banana plugs.
