If the foam surrounds are original expect to need spend some cash to replace them. At least 25$ if you diy, much more if you have it done. If they need surrounds and are missing a grill the price is too high for me personally, YMMV.
Shouldn't need to replace the foam on 4024A. It's the foam on 4029s that rots. I sold one pair for $125 and one pair for $95. The guy that paid $95 drove about six hours one way to pick them up.
Test them out and if you like the sound offer a $100 because of the missing grill....
I have the 4029s.....I love these speakers and my grills are out in the garage do not even miss them....
