Yeah matching with another brand is practically impossible. I might be able to match with the newer version of the driver Dynaudio MW 182 but it's still different and John Dunlavy was very particular about his use of matched drivers for these speakers. It just shocks me how little interest Dynaudio has in selling me drivers.
I get the "supply chain" issue and all, but at least respond to my latest inquiries.
Also, new original woofers from Dyn are $282 while the replacement MW182 is about $350 each. So these aren't just off the shelf drivers.
