INTRODUCTION

The RF Punch Woofers are a full line of low frequency drivers sized

from 8" to 18" and are available in 4 or 8 ohm impedance. The RF

Punch woofers were designed for use primarily in small, sealed

enclosures. By utilizing the latest materials and construction tech-

niques, we are able to offer a speaker with high output at low

frequencies while requiring a minimum of operating space.

TECHNICAL DESIGN FEATURES

◆Stamped Basket

TheRFPunchWoofersuseastampedColdRolledSteelbasketwhich

is rigid and lightweight. The basket is finished in a corrosive resistant

powder coated applied process used in many automotive applica-

tions.

THE RESULT: A lightweight and rigid woofer

◆PVA Cone

The cone material used is spruce pulp paper. 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

resistantPolyVinyl Acetate(PVA) Emulsion which increasesthe cone

rigidity and lowers distortion.

THE RESULT: Increases cone rigidity and lowers distortion

◆Inverted Dust Cap

Theuseoftheinverteddustcapservestoincreasetheconerigidityand

improve the power handling by forcing more air through the voice

coil.

THE RESULT: Increases cone rigidity, smooths frequency response

◆Four-Layer Voice Coil

lowers the Fs of the speaker for better low frequency response and

increases the power handling.

THE RESULT: Increases XMAX and power handling

◆Dual Laminated Foam Surrounds

by making the woofer mechanically stronger.

THE RESULT: Adds mechanical strength

◆Hyper-Extended Pole Piece

The pole piece has been extended to provide a more linear magnetic

field for the operation of the woofer. This lowers distortion and

provides the woofer with better low frequency response.

THE RESULT: Lowers distortion and provides better low frequency

response

◆Vented Bumped Back Plate

The back plate has been stepped deeper to allow the woofer more

excursionwithoutbottomingout.Thisenablesthespeakertobeused

in a smaller enclosure. Additionally, the back plate is vented with a

radiused aerodynamic back vent which efficiently and quietly circu-

lates cool air around the voice coil.

THE RESULT: More excursion and increased power handling

Building an Enclosure

Toworkproperly,thewallsoftheenclosuremustberigidandnotflex

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

operation. For optimum performance, we recommend using 3/4"

MDF (Medium Density Fiberboard) and internal bracing. The enclo-

sureshould be gluedtogether andsecured with nailsor screws.MDF

is porous; therefore, it is suggested to also seal the outside walls with

polyurethane.

Calculating Volume

Calculating volume is merely a matter of measuring the dimensions

in inches and using the formula:

1728"

Height x Width x Depth

Box Volume =

(cubic feet)

Iftwofacingsidesareofunevenlength,addthemtogetheranddivide

by two to take the 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 internal volume. The amount of air displaced

by each model is listed on the specification sheet and should also be

subtracted from the gross volume calculation.

Subwoofer Crossovers

There are two operational types of crossovers, passive and active.

Passivecrossovers(coilsorinductors)areplacedonthespeakerleads

between the amplifier and speaker. An active crossover is an elec-

tronic filter which separates the audio signal fed to different amplifi-

ers.

For optimum subwoofer performance, we recommend using an

active 80-100Hz low-pass crossover at 12dB/octave.

Wiring Configurations

Three configurations for connecting speakers to an amplifier

are Series, Parallel, and Series-Parallel wiring. A Series con-

figuration consists of two or more speakers wired in an string

(end to end). A Parallel configuration consists of two or more

speakers wired with the common terminals connected across

eachother.ASeries-Parallelconfigurationisacombinationof

both methods. Determine which method will be compatible

with your amplifier.
