Infinite Baffle
Storage or
Cavity Area
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
power handling when compared to fully enclosed applications
such as sealed or vented enclosures.
Wiring Configurations
By varying the wiring configuration of your speakers you can create
an impedance load to match your system. Altering the wiring configu-
rations 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 configu-
ration 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.
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 that separates the audio signal fed to different ampli-
fiers. For optimum subwoofer performance, we recommend using an
active 80-100Hz low-pass crossover at 12dB/octave.

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.
