"wood, metal, magnet, copper" - are all going up in price.
But if you look at guitars, they use all these materials and yet you can now buy a better Chinese guitar for 1/4 the price of that from the old oligopoly suppliers, so there must be scope for Chinese brand speakers.
I expect most speakers bought in the west are made in China, but you are still paying a ton for the familiar badges - there is scope for Chinese brands to cut out what is essentially an expensive middle man. Especially now their electronic kit has cut through so successfully. I think some familiar audio groups have already been bought up by Chinese firms.
