This woofer provides added versatility over single voice coil woofers by allowing the use of both channels of a stereo amplifier to driver one speaker, and the ability to wire the voice coils in varying configurations. They feature polymer laminated paper cones, treated foam surrounds, and vented pole pieces with back plates. This driver features a fully shielded motor. Note: All parameters are with voice coils connected in parallel.
