There shouldn't be a buzz at all, clum or otherwise. Just a click (small speaker) or thump (big speaker).
On the buzzy speaker, try gently pushing the cone by hand. Does it seem gritty or smooth?
(I've been living in GB for nearly 20 years, and I've never heard "clum" before.)
When I pushed the cone by hand it was pretty stiff, would need to give it a bit of force before finally moving. I get the multimeter today so will do some readings tonight of the woofer and the tweeter. Should I test anything on the crossover?
