Some wisdom regarding speakers

[Lex]

 
 Any worth of getting used 10 inch speakers from old Peavey Backstage (late '70, CST), so called 'squareback' for an external cab?
 I mean, Im 'educating' my self and trying many things just to understand what Im hearing (and why of course).
 It brings (un)necessary costs with it.

 So, would I be just better to go for a new modern speaker(s) or take a risk and spend less money (about 1/3 of the price of the new one) for my 'tests'?

 Im I reasonable ..?

You like the sound of the speaker or you don't.  The speaker plays well or it doesn't.  The cone is in good shape or is getting frayed.  Etc.

Thanx Enzo,

this means: there is no way to be reasonable but to try it all ..

was a bit afraid of that. It's a justification of GAS ...

Cheers

If you need to buy some speakers anyway, and these are 1/3 the cost?  I would take the chance (assuming they're in good working order). 
You won't be able to try the new ones and might not like them either.
