Introduction
The RF Punch HE Woofers are a full line of low frequency drivers sized
from 8" to 15" and are available in 4 or 8 ohm impedance. The RF Punch
HE woofers were designed for use primarily in small, sealed or ported
enclosures. By utilizing the latest materials and construction techniques,
we are able to offer a speaker with high output at low frequencies while
requiring a minimum of operating space.

Installation & Owner's Manual
Recommended Enclosures
This manual outlines 2 specific types of enclosures that provide distinctly
different performance. This section is to help you decide which type is best
for your application.
Sealed
Sealed enclosures are the simplest to build. The most important part of
building a sealed enclosure is to make sure that the enclosure is airtight.
Using glue and some type of sealant on all seams will ensure solid con-
struction and prevent air leaks. The box volume will directly impact the
performance of the speaker. Larger enclosure will provide flatter response
and deeper bass where smaller boxes will provide a bump in the response
curve and generally higher output for greater SPL.
Advantages of sealed enclosures
•Small enclosures
•Linear (Flat) response
•No port noise
•High power handling at all frequencies
•Excellent for sound quality

Recommended Enclosures
Vented Enclosures:
Vented enclosures vary only from the sealed enclosures in that a vent or
port is added to “tune”the enclosure. The enclosures recommended are
designed for great overall performance. Larger boxes tend to be easy to
tune to lower frequencies while medium and small boxes are easier to tune
to higher frequencies. The vented design is less linear in response than the
sealed box with noticeably more output at the tuning frequency.
Advantages of vented enclosures
•Higher average output than sealed
•Tuning frequency can be easily adjusted by changing port length
•Deep bass response with lower power requirements
•Great for high output with limited power

Building an Enclosure
To work properly, the walls of the enclosure must be rigid and not flex
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 enclosure should be glued
together and secured with nails or 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"/(cu in/cu ft)
Height”x Width”x Depth”
Box Volume=
(cubic feet)
If two facing sides are of uneven length, add them together and divide by
two to take the average. Using this number will give you the volume with-
out 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. Passive
crossovers (coils or inductors) are placed on the speaker leads between the
amplifier and speaker. An active crossover is an electronic filter which sep-
arates the audio signal fed to different amplifiers. For optimum subwoofer
performance, we recommend using an active 80-100Hz low-pass
crossover at 12dB/octave.
