Altec A7 yay or nay?

I have the opportunity to buy  Altec A7 cabinets ($100 a pair) and Horns ($260 a pair) without any cones to either.
The cabinets and grills are in great shape as is the Horn.
My question is, is it worth a punt? as a DIY project that has to be done on the cheap.
Any suggestions as to alternative cones/crossover would be greatly appreciated. 
The chap does have the crossover also, not sure what he is asking though.
This is more of a whim purchase and not a necessity.
I know one thing, it is going to be hard to slip them into the house without anyone noticing, lol...
