Snell Type A


I found a pair of Snell type A speakers at an estate sale the owners agreed to $250 for the pair.  They say the speakers  work.  They look in decent shape.  Is that a good price assuming they are working and a follow up question.  I see they show a 4 Ohm input; will my mid-level Denon AVR-X3300W power them?

Well, I got them, hooked them up and they sound terrific.  I’m wondering how to take the speaker grill off and see what it’s gonna take to replace the fabric on the top section.  Gonna look around Baton Rouge / New Orleans to see if a shop can tune them up as needed.  I will remove the bottom piece of wood to look at the woofers. 
Well I took the bottom wood off and discovered the woofer foam is broken apart.
