Spec me some front door loudspeakers

[snowdog]

My drivers side front speaker has been giving knackered sound, so I opened it up and found this:

So obviously, I want to replace it to regain normal sound, what would you guys recommend for a set of front speakers, budget is about 100€ ( though I might buy one for now ( for the knackered one) and one later ( passengers side front speaker is still fine ) if I can't get any decent speakers for that price). Any ideas what size this is ? And do I need some kind of special bracket for it or whatever ( I can't seem to see if it's a bracket and a speaker or just the speaker that looks this way...). This is the back :

Will any 4ohm & same size speaker work or do I need some kind of special bracket ?
Anyone know some nice speakers? I mainly listen to classic & prog rock...

Speakers come in pairs, so buying one now and one later will be difficult

For that sort of price(I dont quite know what things are like over there) Have a look at Hertz speakers. They are good quality and reasonable value

You need component speakers and ones that fit your car doors and maybe some sort of bracket! It’s not as simple as buying any sort of pair and installing them! Look on your owner’s forum and ask for some tips on which fit and see what people recommend, like the size and depth of the cone etc...
