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 took the bottom wood off and discovered the woofer foam is broken apart. 
Just as I thought! Age ruins foam! Do what I did: get a pair of 10" woofers with rubber surrounds. Mine came from a trashed pair of AR 2's. They fit perfectly in my friend's Type A's. He was very happy with the result!
