re-finish of dunlavy speakers?

A serious answer would require a picture to assess contours and some info from Dunlavy or other owners as to the original finish product used.
Certainly it can be done.
I would be glad to help. E-mail me.
But consider that a competent cabinet maker could probably do justice to the speakers and make a profit at $3- $500 plus the cost of veneer.Or spray tem with 5 coats of very high quality paint and a clear coat for just the $300 or a little more.

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

as far as the value ging through the floor they already went once the shop closed it's doors. From my point of view the out-of-production status should have sent prices straight up since they are still some of the best sounding speakers ever. Make em pretty and enjoy them.

The Dunlavy's are descent speakers. Sold em for years(sound in the ear of the beholder. They had speed, dynamics, coherency, and pace going for them,that's certain.
But as a speaker line, let's face it, they weren't anything super highly coveted by the masses, that's for sure. I sold em in a high end store, and they weren't "flying out of the store" anyway. I actually went to the factory and talked to john once. That was fun.
Anyway, I see speakers like cars...the second you drive em off the lot, the value drops like a rock!!! You couple that with the fact that you can't get proper parts for them anymore, and you have challenges if you blow something.
I've blown many drivers on Dun's over the years, so be careful, have enough power on tap, run em as "small" for HT!(yess!!!!!!!!), and don't do something stupid with them, like unplug your amp connections with the equipment on!!!!

If they are truly an oak veneer, you should be able to refinish them by stripping the black (laquer?) and applying a stain then your choice of poly or laquer. I did this to my Alon V's and used a blended stain (provencial,walnut,and mahogony) then sanding sealer, then 9 light coats of clear laquer (sanding between coats).

The only costs are the stripper (zip strip), the coatings, and sandpaper/steel wool. You can always do new grill cloth (but I do not like Parts Express cloth). I got mine from a local speaker maker so that would not be an option for you. I would look around and have the vendors send small samples until you find what you are looking for. Good luck. - Tim
