Yes, it does. It will not respond in the same way it was designed to if it isn't. This will result in a change in the way it sounds. If it's one of a pair, there will almost certainly be a noticeable difference between the two.
To remove a magnet in a speaker, first detach the grill in the front of the speaker, second unscrew the speaker after that remove the speaker from the cabinet and cut the speaker cone. Lastly, gently discard the magnet from the speaker cone.
A loud speaker (like other speakers) produce sound (which is actually vibrations in the air heard by the ear) with a permanent magnet and a temporary magnet in wire form that is wrapped around the permanent magnet. (or a magnet that can be turned on and off by electricity) the speaker translates the sound into a series of electrical currents and then produces the electricity to alter the temporary magnet and making the magnets vibrate and in turn vibrates the air.
The magnet is part of the 'motor' of the sub. The coil inside the magnet has alternating current running through it. The coil acts as an electromagnet and pulls itself up or pushes itself down moving the cone of the speaker. The bigger the magnet, the stronger the magnetic field inside the speaker where the coil is.
Definitely not. Sound quality depends on so many different things.
No, but placing a video tape on a speaker will ruin the tape
There is a magnet in the both the microphone and speaker. They change differences in air-pressure (in the microphone) to electrical pulses, and in the speaker, they cause the cone to vibrate - creating sound.
From what i have been learnt, the magnet is connected to the diaphragm (the material which covers it) of the speaker and as electric current is passed in this causes the magnet to 'Push' and 'Pull' on the diaphragm making this move resulting in sound waves being produced, these sound waves then enter your ear making you hear the noise. So the magnet helps produce the sound you hear from a speaker.
A magnet
At the back of the cone where the wires connect in
Figure it out yourself
There is a bolt through the back of the woofer enclosure. you can remove the enclosure and remove bolt...big pain in the "asprin" or you can do what I did and cut everything off the speaker ,just leaving the magnet. Then you get a huge pipe wrench , and flek magnet...bolt ... back and fourth till it breaks. It takes a lot of arm power .....but it was easer than removing the whole enclosure.. I am not saying that this is a good idea......but it worked for me.
The electromagnet is used to vibrate the diaphragm of the speaker and a given rate (frequency) to produce a given sound.
