Introduction
The Punch HE2 DVC, Punch HX2 DVC, Power HX2 DVC are high perfor-
mance, 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 mini-
mum of operating space.

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
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 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
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

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 give
a range of options for impedance load. Series, Parallel, or Series-Parallel
wiring configurations are different techniques for wiring speakers that pro-
vide 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 the
number of woofers and the impedance of your amplifier.
