As many know, guitar speaker needs some breaking-in time to sound the best they could, but I was curious to find out what exactly changes as speaker "breaks in" So I compared speakers that I have played for last year and brand new speaker that been played just for couple minutes before recoding this video. I did my best to achieve exactly the same mic placement(dead center on cap, right in front of grill) but as you may know every single speaker sounds bit different from others, so on this video it's three old speakers and one new. I think that fresh speaker sounds more flubby, and somehow produces more unwanted frequencies and whereas "breaker-in" is more focussed and tighter with all frequencies that you want. But it's up to you to decide. Only thing to remember, that if you buy brand new cab or speaker, give it some good run at loud volumes before make your mind if you like cab or not.
