How does the voice coil interacts with the magnet on the very bottom of the speaker?
The magnet is permanent, and the voice coil magnetism alternates with the current, pushing the cone outward against the magnet or pulling it inward towards the magnet as the current changes direction.
Why would a kicker 15 L7 work from time to time or when you push the sub in Is this a blown voice coil?
No, it's not necessarily a blown voice coil. I am actually going through this right now. I found 2 months ago that suggested I take the woofer out of the box and look at it and inspect it. Sure enough, I noticed 1 tiny wire separated in an awkward spot beneath the woofer. I believe by re-attaching this wire the problem will be corrected, mind you I had the same problem as far as pushing it in.
What does positive of the coil mean?
The COIL HAS A POSITIVE AND A NEGATIVE TERMINAL. If you look at the top of the coil, it is generally marked + and - on the top.
What is the function of an electrical coil in a basic circuit?
There are a couple of examples that come to mind where there is a coil in a circuit. One is, the coil is used as a choke to block harmonics from going down the electrical line. Another example of a coil in the line is the coil in a magnetic contactor. When this coil is energized the contacts of the magnetic contactor close.
What is coil span factor and distribution factor?
coil span or coil pitch is defind as the distance mesured in terms of armature slots(or armature conductors) between two sides of a coil.

How does a speaker work in a circuit?
They will either pull in or push out depending on the polarity of the DC voltage and remain stationary. This is a bad idea as the DC resistance of the voice coil is much less than the AC impedance of the voice coil and it is possible to overheat and burn out the voice coil due to the much higher current the DC voltage can produce in the voice coil compared to the AC voltage that would drive the voice coil in normal operation.
When connecting a dual voice coil sub in series what is the proper wiring configuration?
When connecting a dual voice coil sub in series you should use the powered subs.
Does the Legacy Car Audio LW1549 come with dual voice coil?
The Legacy Car Audio LW1549 comes with a 2.5'' High Temperature Dual Kapton Voice Coil.
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.
How do you wire Voice coil?
Unless you are an electrician, I would not attempt it, you will need a special tool do wrap it around the axle (The post in which the voice coil moves up and down on). Either have a tech do it for you, or replace the speaker.
What has magnet got to do with musical equipment?
It is the medium by which a voice coil reacts to or is stimulated by. Reacts: As in a speaker the power sent to the coil creates an attraction creating movement of the cone that produces sound. stimulated : As in a microphone the voice coil is vibrated around a magnet which produces electricity that is amplified to be heard.
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.
What does the term dual voice coil mean in regards to car audio speakers?
AnswerDual 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 examplesAlso 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 does the voice coil interacts with the magnet on the very bottom of the speaker?
The magnet is permanent, and the voice coil magnetism alternates with the current, pushing the cone outward against the magnet or pulling it inward towards the magnet as the current changes direction.
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 is the part of a loudspeaker that vibrates to make sound?
a speaker uses a voice coil a coil copper wire and a magnet and pole to vibrate a cone
