NOTE: When using vented enclosures, for maximum reliability and
power handling ensure, that a subsonic or "infrasonic" filter is used
so that only usable low frequency signal is sent to the subwoofer.
Infinite Baffle
An Infinite Baffle enclosure design represents an application where
the compliance of the air volume within the enclosure is greater than
the compliance on the speaker's suspension (Vas). An infrasonic filter
is required for reliable performance.

IMPORTANT: A subsonic or "infrasonic" filter at or above the
resonant frequency (Fs) of the speaker is required.
NOTE: Infinite baffle installations will result in lower speaker

Wiring Configurations
0.12 (3.4)
By varying the wiring configuration of your speakers you can
H
create an impedance load to match your system. 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
35
end. Parallel configuration uses two or more speakers wired across
36
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.
Subwoofer Crossovers
4 x 14
There are two operational types of crossovers, passive and active.
)
10.16 x 35.56
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.
