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.
