Dual Voice

Whats the difference between single voice coils and dual voice coils on subwoofers?

Which one is better and does dual or single produce different frequency, or different ohms, or watts or what?

Dual VC subs offer greater FLEXIBILITY in wiring connections when configuring multiple amp and speaker systems. One is not necessarily “better” than the other regarding frequency response or power handling capability, or quality of construction.

The key difference between single and dual voice coil sub woofers is the multiple wiring options DVC subs offer. The following examples highlight the various possibilities in wiring, copied from the Crutchfield web site.

PARALLEL: A dual 4-ohm voice coil sub woofer with its coils wired in parallel presents a 2-ohm load to your amplifier. Since an amplifier produces more wattage at a lower impedance, the parallel connection ensures you’ll get the most output from your amp. In the same fashion, if you have a stereo amplifier and two DVC subs, wire both subs for 2-ohm impedance (one per channel) for maximum output.

SERIES: Series wiring lets you configure multiple woofers to one amplifier at an acceptable impedance. Wire both coils in series for an 8-ohm impedance, and then wire two 8-ohm subs together in parallel for 4-ohm total impedance (perfect for most 2-channel amps bridged to mono operation). Another example: if you have a high-powered 2-channel amplifier, wire four 8-ohm subs per channel (each channel sees a 2-ohm load).

INDEPENDENT: You can wire each voice coil to a separate channel of your amplifier, if you prefer not to bridge your amp. Independent wiring is a nice option if you’re wiring two DVC subs to a 4-channel amplifier — one voice coil per channel.
