Either a Punch HE2 DVC, Punch HX2 DVC
or Power HX2 DVC Woofer
Installation & Operation Manual
The Punch HE2 DVC, Punch HX2 DVC and Power HX2 DVC are high performance, low frequency
drivers with dual voice coils. These woofers were designed for use primarily in small sealed and
small 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.
DESIGN FEATURES

4
RECOMMENDED ENCLOSURES
This manual outlines two specific types of enclosures that provide distinctly different performance.
This section is to help you decide which type is best for your application.
SEALED ENCLOSURES
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 construction and prevent air leaks. The box volume will directly impact the
performance of the speaker. Larger enclosures 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
Punch HE2 & HX2 8"
Recommended Sealed 0.30ft3(8.50L)
Punch HE2 & HX2 10"

Punch HX2 18"

RECOMMENDED ENCLOSURES
VENTED ENCLOSURES
Vented enclosures vary only from the sealed enclosure 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 but 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

Power HX2 12"
Recommended Venteded 2.5ft3(70.8L)
Power HX2 15"
Recommended Venteded 3.5ft3(99.11L)

WIRING CONFIGURATIONS
By varying the wiring configuration of your speakers you can create an impedance load to match
your system. Since each voice coil of a DVC speaker carries its own impedance, altering the wiring
configurations gives a range of options for impedance loads. Series, Parallel, or Series-Parallel wiring
configurations are different techniques for wiring speakers that provide different loads. Series
configuration is a string method where speakers are wired end to end. Parallel configuration uses
two or more speakers wired across common terminals. Series-Parallel configuration combines both
techniques. Choose the wiring diagram below that corresponds to the number of woofers and the
impedance of your amplifier.

8
SPECIFICATIONS
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:
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 separates the audio signal fed to different amplifiers. For optimum
subwoofer performance, we recommend using an active 80-100Hz low-pass crossover at
12dB/octave.
Box Volume = Height “x Width”x Depth”
(cubic feet) 1728 cu. in./cu. ft.
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 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.
