What does the term dual voice coil mean in regards to car audio speakers?

Dual Voice Coil in regards to subwoofers means there is 2 positives and 2 negatives. Its just used to wire up different ohm levels. Like if u have a subwoofer that are dual voice coil @ 4 ohms then u can parallel or series wire it to become Single Voice Coil @ 2 ohms. Google the word Series Wiring or Parallel Wiring for examples
Also this type of speaker is one of the few that can be connected to 2 different amplifiers at the same time and still work properly. One coil is connected to the car stereo and the other coil is connecter to my scanner.

How do speakers produce the bass and treble at the same time?
There are a few types of speakers, but generally, the "voice coil" type speaker is the most common used for sound systems. It consists of a strong and lightweight paper or plastic cone which is attached to a coil. The coil is aligned so that it surrounds a magnet, but the magnet does not touch the coil. When a voltage potential is connected to the voice coil, the coil and therefore the cone moves. By applying voltage at a specific frequency, the voice coil will move in synchronization with the electrical frequency. The voice coil can be moving slowly, as is required by a low frequency sound, and at the same time a high frequency electrical signal can also be injected into the signal. By overlaying multiple electrical frequencies at the same time, the voice coil will move to produce a wide range of simultaneous sounds.
What is an audio coil?
An audio coil is another name for a telecoil, a coil of wire incorporated into modern hearing aids which respond to electromagnetic signals.
What is a speakers coil?
nothing
Will stereo speakers that handle 275 watts handle a home stereo system pushing 105 watts per channel?
yes it will, but if you try to turn it up to loudly you may cause damage to the voice coil of your speakers
Can you use a 450 watt amp on 600 watt speakers?
Yes, if you don't turn it up all the way. Excessive power to speakers will result in distortion and possibly even complete failure of the voice coil and/or cone.
What is the role of a magnet in woofers?
The voice coil of a loudspeaker is placed in an annular space within the magnet assembly and is connected to the loudspeaker's paper cone. An audio signal creates a current in the coil and this generates a magnetic field around the coil which reacts with the permanent magnet of the woofer. The coil and cone move in and out like a piston in a car engine depending on the polarity of the audio signal. This is called the 'Motor effect' and is basically a linear motor.
Will using one coil on a dual coil speaker damage it?
with only one coil hooked up, a dual voice coil speaker will suffer a loss in reference efficiency of about 3dB (only half the coil windings are being energized) as well as a significant shift in its Thiele/Small parameters. This renders any enclosure calculations inaccurate unless you remeasure the speakers parameters with only one coil hooked up. Failure to account for the different parameters of a dual voice coil speaker with only one coil powered can result in very poor performance.
What kind of speakers should you get for your DJ set up?
Pair of Dual 15" PA DJ SPEAKERS 1000 Watts PRO AUDIO - Band, Bar, Wedding, Church 500 Watts RMS; 1000 Watts Peak Each Woofer has 50 oz magnet and 2" voice coil Two 2x5 Tweeter Frequency Response: 30Hz to 20kHz Steel Grill over each speaker.
How does loudspeaker use electromagnet?
The exceptionally strong and steady magnetic field reacts with the alternating field created by the alternating current produced by the audio current flowing in what is known as the voice coil. The Voice Coil is physically attached to the cone that moves the air so you can hear the pressure wave that simulates the current wave-form.
Why does a speaker need an electromagnet not a permanent magnet?
One of the main kinds of speakers needs both. Sound in the form of varying electricity is fed through part of the speaker known as the 'voice coil' which is actually just an electromagnet. Since the electricity in it is varying the magnetism produced by this coil varies too. The voice coil is placed close to a permanent magnet and the voice coil is permitted to move back and forth in response to the electricity going through it. A big cone is fastened to the voice coil to transmit the movements of the voice coil to the air more efficiently. Thus overall the permanent magnet and the electromagnet work together to produce the sound waves that we hear from a speaker. For a more detailed explanation go to the How Stuff Works web site and search for speaker.
