Punch DVC Woofer Trim Ring Screw Pack Installation & Operation Manual The Punch DVC Woofers 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 FEATURES4 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:

• Linear (Flat) response

• High power handling at all frequencies

• Excellent for sound quality

• Extended low frequency output when compared to vented enclosures5 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 power6 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.7

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. 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.8 Specifications subject to change without notice SPECIFICATIONS FEATURES - Punch DVC P3
