Series 1 Woofer
Owner's Manual

INTRODUCTION

This manual contains information on the construction, installation
and operation of the Series 1 low frequency speakers. We recommend
you keep this manual for future reference.

The Series 1 Woofers are a full line of low frequency drivers ranging
in size from 8" to 15" in diameter. System compatibility is ensured by
offering each size at four and eight ohm impedance. Designed to offer
Rockford Fosgate quality in an affordable speaker, the Series 1
Woofers offer the beginning car stereo enthusiast an opportunity to
enjoy solid low frequency music reproduction. Our engineers have
selected materials and techniques used in building our speakers
which offer performance and reliability comparable to other speakers
selling for much more.

DESIGN FEATURES

The following section describes the methods used in constructing the
Series 1 Woofers and how each was optimized.

Black Anodized Aluminum Voice Coil Former – To improve the
reliability of the voice coil, it is wound on a black, anodized
aluminum former. Because aluminum is an efficient thermal conduc­tor, it keeps heat from concentrating in the voice coil during normal
use.

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 form the voice coil assembly.

PVA Treated Paper Cone – The cone is constructed from a light­weight, rigid paper material. The cone is treated with Polyvinyl
Acetate which lowers the resonance and reduces distortion. The PVA
also reduces damage from the harsh environmental conditions typi­cal of a car interior.
