the sound is created in the voice coil then transmitted to the air via the diaphragm so different materials will create a different sound

The electrical energy in the voice coil makes the whole unit move in sympathy with the signal. That in effect "makes waves" by stirring the air in sympathy. It is those "waves of air" that stimulates the sensors in your ears to hear it. This is why there is no sound in a vacuum. (Until 'indoors gets the Henry out at least.)

yes correct t but the material still effects how it's transmitted to the air, which is why they don't opt for paper diaphragms in compression drivers and alike I think we are going to have to agree to disagree

The density of materials is very important, and is the same with cabinet construction

One of those debates, which had been raging for decades, is about metal vs. paper or cloth diaphragms. Each has its merits, and everyone it seems, has their preferences. Let's discuss the basic function of the loudspeaker, and how the diaphragm is supposed to function, and what is actually happening in the “real world”.
An ideal loudspeaker diaphragm would never flex, thus it would exhibit perfect pistonic motion. It would always be infinitely rigid, well damped, and inherently in that characteristic, the speed of sound through the material would be infinite, thus the mass would ideally be zero and the break up mode frequency would be infinity. Loudspeaker engineers have a word for this ideal cone material. Unobtainium (apologies to James Cameron from Avatar).

By that logic though B Class amps would be better that AB and much better than A class as there would be less distortion and a "cleaner" sound. But A class amps sell for many times more than B class whilst having much higher THD figures.
Audio technology and peoples ears very rarely "ideal".

But people still spend shedloads on their car stereos and that in a noisy environment.

TBF they are generally spending on an improvement and volume. Audiophile audio in a motor is just stupid.

You of all people Wozzaaah know we only need a snippit for a full on debate

To get something worth having I think you will need to spend more the 20 quid on each driver the drivers you posted were 88db efficiency to get another 3db you would need to add another 50 watts, some drivers will produce 101db using the same power

Look on ebay for a second-hand set with decent drivers it will be cheaper than messing around with drivers that were never meant for the enclosure.
Realistically though I would advise to get some second hand mission 780 or 780se (if you like the mission sound) as they are far better and the last missions made in England. Just make sure they have had updated drivers fitted - preferably the second gen French ones not the Chinese ones from IAG factory.
When I say 780/780se I'm talking the year 2000's on model (not the really old ones confusing as they repeated numbers). And avoid stuff after like the 790 series = a bit pants and made in China

There is someone selling used drivers on eBay but the problem is if mine have gone like that along with many, many others I don't know how long those will last before they go the same way. At £45 each it's even more of a gamble than the monacor ones.
I love the mission sound and have just googled the 780se but if I bought those I'd also need to buy some decent stands and with a lunatic dog in the house floorstanders are safer.

you think yours have had it, this was on a 21inch sub driver before we re-coned it
