This is not a "project."
These wonderful classic speakers are in total operating condition. Judging from the way they sound when driven by my Plinius amp playing rock, folk, and classical records, they do not need anything repaired or replaced. The surrounds and cones on all drivers look totally intact. The 3-way switches appear to be working fine, both of them, a fair indication of capacitor function.
That they also look very good for all their 40 years of life, is a bonus.
If you're into Golden Age "New England Sound," these are your guys.
