Not currently was meant to mean "no longer" referencing the comment about plywood coming from Finland in the past, as well as implying that with Putin's aggressions the Soviet Union or a facsimile may return in the future. Apparently that went over a lot of heads and I could have been more clear.How old are your political maps?
Self-explanatory. I work in the wood industry and there is a shortage of Russian Baltic birch plywood. Or they can't get it at a price that is profitable anymore.
This is bound to affect higher end amp/cab makers and they will have to go to something cheaper.
And we know the drill, once they see they can sell cabs made from cheaper materials at the same price as more expensive materials, they won't go back to the Russian Baltic birch.
The superiority of this wood is a proven fact. As shown by boat makers and furniture builders and many other industries that use it for certain designs because nothing else will hold up.
The baffle is not critical too, correct?How about Finnish Birch & / or Italian Poplar?
Either way I have heaps of great older Bogner Cabs & an older Bad Cat Cab.............I'm a happy camper.
Headshells are not critical though...........use Poplar Ply, Paulownia or Pine.
Wouldn't surprise me if someone made Paulownia Ply going forward.
The baffle is not critical too, correct?
So is it not possible to replicate the plywood in other regions?The difference is between what is marketed as "Baltic birch" and the big box store "birch plywood" which is cheaper. I have never seen Baltic birch specifically marketed as Russian although that is where much (but not all) of it has been coming from.
Baltic birch is a void free plywood made with even layers of birch. Birch plywood can have voids and is made with a thin veneer of birch over thicker layers of wood and fillers that may or may not be birch.
It’s only tonally important to hifi speaker builders because the voids can cause resonance problems. And like a lot of things in the guitar world, the traditions of hifi were absorbed into the guitar world because the original amp manufacturers catered to the P.A. systems market even more than guitar. Those traditions just became talking points over the decades.
My cab builder is getting it from Canada. Didn’t know about the trade name, my builder used the same name too. He convinced me that since I am building a pine cab and instead of using Russian Baltic birch which is in short supply for the baffle, he will use Canadian and won’t impact tone.Right now, all plywood from anywhere is in short supply, and prices are nearly double. Baltic birch plywood is a trade name for a plywood made from plys that are all the same thickness. I have had it come from Eastern Europe, and from China.I would avoid the stuff from China, I had a piece de-laminate when I was cutting it on a table saw. The piece kicked back underneath it self, and almost got me. The de-lamination would be a major concern in speaker cabinets, panels can buzz, and are not structurally sound. There is a product called Apple Ply, that does not have as many plys as Baltic, but is very sound, and domestic.
