Does anyone have a Celestion Hot 100 12 inch 16ohm Speaker that they wish to sell?
Please contact me with a price and we'll work out how to get it to me.
Cheers, Alan.

There are indeed mate.
However, firstly I'm looking for the one that someone has and doesn't need anymore.
Imagine the scene, Sunday lunch;
"Pass the Horse Radish sauce dear".
"Certainly, where is it?"
"Why, it's right there next to that Celestion Hot 100 12 inch 16 ohm speaker".
"Ah, so it is. What a pity we don't know somebody who could make good use of it".
"I say dear, I seem to recollect that nice Mr. Bakewell wanted one recently".
"Spiffing, I'll telephone him first thing tomorrow. He retires early in the eventide,
something to do with walking those Springers at some unearthly hour in the morning"

It didn't have to be that exact scenario.
It could, of course, have been next to the Colman's Mustard.

"Dad"
"Yes, small boy", ( who really should be seen but not heard, especially at the dining table )
"Why are all the knives and forks stuck to the Celestion Hot 100 12 inch 16 ohm speaker"?
"That's to do with the magnet son"
"Magnet Dad"? "Why does a Celestion Hot 100 12 inch 16 ohm speaker need a magnet"?
"Well son, it's like this"
When the electrical current flowing through the voice coil changes direction, the coil's polar orientation reverses. This changes the magnetic forces between the voice coil and the permanent magnet, moving the coil and attached diaphragm back and forth.
So how does the fluctuation make the speaker coil move back and forth? The electromagnet is positioned in a constant magnetic field created by a permanent magnet. These two magnets -- the electromagnet and the permanent magnet -- interact with each other as any two magnets do. The positive end of the electromagnet is attracted to the negative pole of the permanent magnetic field, and the negative pole of the electromagnet is repelled by the permanent magnet's negative pole. When the electromagnet's polar orientation switches, so does the direction of repulsion and attraction. In this way, the alternating current constantly reverses the magnetic forces between the voice coil and the permanent magnet. This pushes the coil back and forth rapidly, like a piston.
When the coil moves, it pushes and pulls on the speaker cone. This vibrates the air in front of the speaker, creating sound waves. The electrical audio signal can also be interpreted as a wave. The frequency and amplitude of this wave, which represents the original sound wave, dictates the rate and distance that the voice coil moves. This, in turn, determines the frequency and amplitude of the sound waves produced by the diaphragm.
"Oh..............so where does the mustard come into it"?

You have too much time on your hands.
