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 asealed enclosure is to make sure that the enclosure is airtight.
Using glue and
some type of sealant on ail 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 abump in
the response curve and generally higher output for greater SPL.
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: H x W x D divided by 1728 (cubic feet).
See
block below.
120.0...------t---1----+--I---+--+---+---+-+------+---1---I---I--+-+--I--+--I
Advantages ofsealed enclosures:
Small enclosures
Linear (Flat) response
No port noise
High
power handling at all frequencies
Excellent
for sound quality
Extended low frequency
output when compared to vented 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.
BoxVolume Height" x Width" x Depth"
Divided by (cubic feet) I 728
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.
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.Altering the wiring configurations
gives arange
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 astring
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 that corresponds to the number of woofers and the
impedance of your amplifier.
Parallel Wiring
(2) 4 ohm SVC Speaker =2ohm Load
SUB'NOOFER 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
that 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.
