I like the idea of doing a "faux(?)" paint finish on the speakers!
My budy does artwork on KTLA Channel 5 a few mornings a month as a spot-light segment(also did Oprah's once!)I've seen him do superb faux work on just about every finish imaginable.
I was talking to him some time back about doing faux paint jobs on speakers, and marketing them! You could, say, on the Dunlavy's, make em look like a giant piece of marble or rock, or fake wood! Why not?!!!
I've seen him take plastered pillars and make them look so much like real marble for instance, that you wouldn't know the difference until you got your face right next to it!!!...why not do something similar on your large speakers!?
Anyway, I think it would be cool as an option, whether you did it yourself(obviously better by a pro), or had someone else do it. I wonder if anyone else has had this done, or considered it???. The options are endless with what you could do with paint, and you wouldn't change the acoustics, or do anything to radical to the structure that couldn't be stripped or even "repainted" if you changed your mind or lifestyle. It's a thought anyway.
As for Dunlavy's "re-sell value", that company is out of business anyway, I doubt the resale will stay. Also, you can't get proper matched drivers anymore for "driver matching", which was a serious design point of those speakers(driver matching that is). If you blow drivers, on those, you're getting a different speaker drivers, that's all there is to itAt any rate, good luck
