They look like very nice speakers. The build quality seems to be very high. They remind me a lot of the ADS speaker line here in the US. If you don't see any posts from Mr. Sanford, PM him. He's a hell of a nice guy and very helpful.

Well, look at that, I'm a hell of a nice guy! Thanks for that...
Sorry, didn't catch your PM & this thread didn't come up in "New Posts" search- yes, there are Quinto 510s here- they, like most of my Cantons, were rescues from folks that were discarding them (REALLY rich folks). Mine are very abused, and have a couple of issues because of that, but if I had a line on some woodgrain cabs in good shape I'd be jumping on them.
I'll try to get some pics of mine so you have a reference for my comments, but picture some nice, white speakers that lived for many years in a hot, humid, chlorine-laced pool house and you'll start to get the idea.
From memory, these are acoustic suspension, ~8" 3-ways with dome mid & tweet. I can take a look at cone material later today. If my surrounds haven't decayed, I'm not sure why ANY would have...that seems strange to me.
I've still got some imbalance issues (haven't used test equipment yet, but it seems one mid is quieter than the other), I'll be checking the x-over some day. ***Keep in mind these drivers are somewhat covered in chlorine scaling, which might explain what I'm hearing.***
I've been listening to these lately as near-field monitors while my JBL L110s have been out for cabinet work, and I have to say they're not my favorite in that application. Mirror imaged, I believe, which is good, but just too heavy on the highs. To me, Cantons are usually a bit bright & shimmery, these are a bit beyond that. In a normal living room, with furniture and drapes and listening from a distance, they'd likely be very good. Currently they're in my under-construction studio control room with hard floors & untreated walls and just over arm's length away from me - too close.
I had picked these up because A] They're Cantons B] They were free, and I'm a hopeless sucker for orphaned speakers, and C] I thought they might make good parts donors for my other Cantons. I've not yet put the time into them to bring them up to performance specs.
Hope that helps...have you seen these pages? Might be some applicable info:
