thoft - sit tight for some first-hand experience here.For my part, I tested the Madisound "drop in" and it is so different that I would never consider it. Anybody want to comment?
The tweeter you want is the rebuild of that particular version of the Dynaudio D28.
Regarding woofers, that was highly specialized. I think Rob Gillum at Coherent Source Service can rebuild yours. I haven't heard of anything else that works.
Remember that these drivers each cover a huge range and the various contouring circuits are specifically tuned to the resonances and anomalies of a particular driver. Generic replacements just don't work. But take courage, we will eventually have a stellar solution for you.
Comments please.
