Hello, Coastsider. I've been posting @ DIY Walsh speakers about my attempts to 'repurpose' some drivers into Walsh-style units with some success. It was suggested to me to look over the Infinity Walsh repair posts, perhaps to glean some insight towards my quest. Viola', your name appeared, and you certainly seemed in 2012 to have a handful of them in hand.
If you don't mind, can you 'mic' the thickness of the cone material? Is it aluminum, or plastic as has been mentioned appearing on some of them? Is the center post attached to the voice coil, or is it simply rigidly attached to the center within the vc? Any thoughts on these units would be appreciated and digested *G*.
