Just listen at moderate levels. You can use a streamer service to play a digital radio station continuously at a lower level when you are not home or doing something else. Break-in won't take long - maybe a few days (100 hours). Since I have only bought used speakers for years this aspect has not been a concern!
Speaker massage ...
Hi there
I don't know how to translate this on english, but new speakers are getting better even more they got played, but how? How do I give them the perfect massage? Do they have to be played loud or on normal sound niveau but for hours? I live in an apartment and can't play loud every day, with respect to the neighbours.
Best regards
