Dual Voice Coils

Dual voice coil subwoofers are becoming a popular choice among car audio enthusiasts who want more flexibility in wiring their sound systems. While typical subwoofers have a single voice coil, dual voice coil (DVC) subwoofers use two separate voice coils, each with its own connections, mounted on one cylinder, connected to a common cone. The key difference between single and dual voice coil subwoofers is the multiple wiring options DVC subs offer.

Impedances for these speakers can be configured in a variety of values including different levels for each one. The most popular format is to have each coil optimized for 4 ohms, although 6, 3, 2, and even 1 ohm coils are not uncommon. Some specialized units may have 4 and 2, or 8 and 4 ohm coils.

Each coil can be connected to separate amplifiers in order to produce a common bass wave from two amplifier channels through a single woofer. Since bass has a non-directional character, this does not interfere with the optimum reproduction of the stereo image in the other speakers.

 

Dual Voice Coil Wiring Options

A wide variety of wiring schemes can be benefical to achieve the highest possible quality sound in a limited amount of area. Using DVC woofers can exploit the maximum potential of the amplifiers specifications.

 

Single DVC Woofer/Dual 2 Ohm/Parallel

A single dual voice coil woofer with 2 ohm voice coils wired in parallel will produce a 1 ohm load to the amplifier.
