I recently acquired a pair of L-19's in need of re-foaming. Starting researching "how to's" I noticed the center cone on images I looked at was inverted (concave). Mine are convex. They are jbl woofers with serial numbers.
Any reason why my center cone would be different?
Thank you in advance for any guidance.
