Celestion Ditton 44 Speakers

Does anyone have or ever had Celestion Ditton 44 speakers? I saw a pair at a thrift shop, excellent condition, cheap, and could not resist buying them. I am currently have them hooked up to my store system (In budget minded virtual systems). Any comments about them? Has anyone ever replaced or upgraded the capacitors in the crossovers of vintage speakers?
My comments after a week of listening: Very listenable; no listening fatigue; punchy bass (they have a 12 inch woofer). However, they are noticably somewhat "muddier" than the CAMBER speakers I have been using. Not lots muddier, but somewhat muddier. By muddier, I mean less precice sounding. (The Celestions are three way speakers, and the Cambers are two way with a 7" woofer, and that may partly explain why the Celestions sound muddier.) I will hook the Cambers back up when I get around to it. However, I would like to try the Celestions in a room that is more appropriatly set up acoustically. If you look at my virtual system, there are serious issues with the room of my store system, but that is where I listen most.
