Punch Power Woofer

Baseplate Label

This manual provides information on the construction, installation

andoperationofthePunchPowerWoofers.Wesuggestyousavethis

manual for future reference.

ThePunchPowerWoofersincorporatethebestavailablematerialsin

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 tech-

niques which make this possible are listed below.

INTRODUCTION

CastAluminumBasket–Thebasketisthesupportingstructureforthe

speakerand mustnotvibrateorflexwiththespeaker'soperation.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

speakerswithavarietyofdifferentterminalssuchasbananaplugsor

spadelugs.Thebindingpostwillalsoacceptbarewireupto12gauge

and are spaced on 3/4" centers to accommodate dual banana plugs.

DESIGN FEATURES

AeroVent™PolePiece–TheAeroVent™providesventilationforthe

voice coil for improved power handling. The AeroVent™ is aerody-

namically shaped to allow passage of large amounts of air without

constricting the air flow which can cause whistling or turbulence

noise.

Suspension – The suspension holds the cone to the basket and

suspends the voice coil in the magnetic gap. The surround, which

supports the cone, is made from a dual laminate foam which

minimizes edge deterioration. The proprietary flat spider design

maintainslinearmotionofthevoicecoilevenathighlisteninglevels.

Voice Coil – The voice coil is wound on a large diameter anodized

aluminum former for highly efficient thermal transfer. The large

gauge high temperature copper wire allows operation at high power

levels.

Cone – The cone is made of a heavy and rigid paper material which

allows for very low frequency response and resists deforming when

driven at high power levels.

LOW FREQUENCY SPEAKER SYSTEMS

ThePunchPowerWoofersrequireanenclosuretoachieveoptimum

results.Theenclosureallowsthespeakertooperateatlowerfrequen-

cies with improved power handling. The two most commonly used

types of low frequency speaker systems are acoustic suspension and

bass reflex. The acoustic suspension enclosure, commonly referred

to as a sealed box, relies upon the changing air pressure in a tightly

sealedchamberforitsoperation.Thebassreflex,commonlyreferred

toasaportedenclosure,usesaventinsertedintotheboxwhichtakes

The Punch Power Woofers will yield optimum performance in a

small, ported enclosure.

USING THE PUNCH POWER WOOFERS

Speakers are built in different sizes to optimize their performance in

different frequency bands. Crossovers are used to route the different

frequencybandsforeachspeaker.Therearetwooperationaltypesof

crossover: active and passive. An active crossover is an electronic

filterwhichisplacedbeforetheamplifierandseparatesthesignalfed

todifferent amplifiersinthesystem.Apassivecrossoverispositioned

after the amplifier and separates the signal fed to each speaker in the

system.Activecrossoversoffertheaccuracyandflexibilityneededfor

asophisticatedsystemandareusedincomplexmultipleampdesigns.

Passive crossovers (capacitors and inductors) allow the use of mul-

tiple speakers in a simple system which can easily be expanded over

time. We recommend using a 6dB per octave, 100Hz low-pass

crossover for the Punch Power Woofers when used with a passive

system.

To customize the installation, try adjusting the crossover point one

octave up or down to optimize the system staging.

CALCULATING LOAD IMPEDANCE

The Punch Power Woofers are used for the sub-bass region, those

frequencies below 100Hz. This is the foundation for the music and

the frequency range you feel. Before selecting the passive crossover

itisnecessarytocalculatetheloadimpedanceofthespeakersystem.

In a series circuit the impedance is determined by the formula:

Rt= R1+ R2+ R3+ etc.

In a parallel circuit the impedance is determined by the formula:

11111

RtR1R2R3R4

Where Rtis the total speaker load and R1, R2, etc. represent each

speaker in the system.

The crossover is connected in line to the positive terminal of the

speakersystem. Thecrossovers areavailable fromAuthorized Rock-

ford Fosgate Dealers.

= + + + + etc.

CALCULATING VOLUME

Calculating volume is merely a matter of measuring the dimensions

in inches and using the formula: Volume = Height x Width x Depth.

Theresult is incubicinches, convertthisto cubic feetby dividing by

1,728(thenumberofcubicinchesinacubicfoot).Iftwofacingsides

areofunevenlength,addthemtogetheranddividebytwototakethe

average. Using this number will give you the volume without the

necessity of calculating the box in sections and adding the sections

together. The thickness of the baffle material reduces the internal

volume so this must be subtracted from the outside dimensions to

determine the internal volume. The speaker itself also reduces the

internalvolume.Theamountofairdisplacedbyeachmodelislisted

on the specification sheet and should also be subtracted from the

gross volume calculation.

BUILDING ANENCLOSURE

Toworkproperly,thewallsoftheenclosuremustberigidandnotflex

when subjected to the high pressures generated by the speaker's

operation. We recommend using 3/4" thick high density particle

board or medium density fiberboard (MDF), which are available at

most building supply stores. For a large box, internal bracing is

needed for reinforcement. The joints should be glued (use non-

flammable carpenter glue) and secured with either nails or screws.

Internally the joints should be sealed with silicon to prevent air

leaking.BecausethehighdensityparticleboardandMDFareporous

materials, it is suggested to seal the outside enclosure walls with

polyurethane.Ideally,theportshouldbelocatedonthesamefaceas

side and back walls.
