Enjoy the journey and play them as you would normally. This is the fun part. There will be several "aha" moments along that way where a number of things will happen; soundstage will open up, bass response will improve...and you will undoubtedly refine their placement, which will yield even further improvements. It takes time to get to know your new speakers, and, hey, if you were to "arrive" at the final destination of speaker break in and optimal placement immediately, you would likely pull a David Byrne and ask yourself, "well, how did I get here."
The best way to break in speakers.
What is the best way to break in speakers? Should the volume be in a low, medium or high level? Is it better to start in low volume and gradually turn it up every 10 hrs or so?
