Hold the phome, honey, I'm speakin' here!
The $30/pr. DIY foam kit is tempting, but... don't see how I could accurately center the cone OD while getting the glue set w/o a jig or something. Such a cone support would be quite helpful during the old foam's removal, I would think, to prevent bobbin/coil damage. A local shop will do the foam for $30 each. Pro-installed foam should be good for 15 years more.
Pulled a midrange driver just for grins. Its magnet is nearly as big and strong-- a real collector item! of steel tools, that is. They are the sound's heart, after all, and coo like a dove. Tweeters still tweet like finches at dusk. Will keep these babies factory stock. :cool:
Thanx again for the help. :)
