"I'll hazard a guess those fine Walsh drivers won't be appreciated too much longer."
The cabinets will likely get recycled with newer drivers for some future buyer looking to save some money compared to new cabinets. I am a fan of those older pyramid shaped cabinets myself.
Maybe if someone were interested and contacted John, he would sell the drivers sans warranty for a reasonable price if the condition and value can be established within reason.
i can't imagine a pair of OHM F drivers in good working condition not having some value, but I do not know what is required to establish level of functionality and value accordingly in that in that all are old and have had third party work done on them prior most likely if still in good general working order. It likely takes some special expertise just to appraise the operating condition and value properly I would think.
