I'm rebuilding a set of Bose 901's, series V speakers.
Before you Bose haters start razing me about the type of speakers I’m working with, let me state that the speakers and most of the materials are hand-me-downs and the goal of my project is to enjoy a speaker rebuild and learn more about the mechanics of speaker fabrication. Don’t worry; I’m planning to build a set of speakers from scratch, down the road.
My question to the experienced is what is a good method for bench testing each of the (18) speakers. I removed all of the speakers from the two cabinets for inspection and to replace the surrounds. After the surrounds are replaced what are my options to test each speaker before I install them back into the cabinets?
The speakers were stored in a garage where they were exposed to a lot of moisture and dust. What other parts of the speakers should I inspect for problems while I have them out of the cabinets? Also, can the magnets weaken in strength, and is there a way to test them?
Let the craziness begin!!!
