Will quickly share a recent experience with Parts Express. I have 2 projects underway; one needs a tweeter and the other a subwoofer driver. As yet, prices have not been a major consideration, but availability has worsened considerably. The tweeter was already on back order but now shows "Advertised price subject to change due to tariff uncertainty".
As for the subwoofer, only needed one of the Daytons, but it stocked out. Ofc, regardless of trade wars, this happens but here is a key difference. When I went to consider alternatives, most of them were out of stock too! Heeding my own guidance, rather than speculate, will let you know. The driver I want is not due back until July.
