Kemper Kone break in necessary?

I believe I read that they are ready to go.

Even if they require break in, most speakers can be done in about 20 hours. Some only need 10 hours.

Same here.

It's a Celestion and I would assume the materials are the same as used in other Celestion speakers. Here's the web page for recommended break-in. If you've already had it for a year or so I imagine it broken-in.
