How can anyone optimize loudspeaker performance within 20 minutes? Figuring out preferences for room placement, toe-in and tilt takes a little bit of time. The drivers (and surrounds) need time to loosening up and the crossover components also need run-in time. A bad loudspeaker won't get transformed into a good loudspeaker, but a good loudspeaker can blossom into a really good loudspeaker with a little time and effort. Personally, I swear by the XLO Burn-In track, but there other methods.
Break In Failed
There is a new set of speakers on the way and after looking for tips on speaker break in, the topic hits left me smirking.
Good advice like face the speakers and wire one out of phase, use heavy blankets and leave on 24-7 for weeks.
The amusing part was exercising them at ~90dB for excursion during away hours. My current speakers have seen that level in my apartment for maybe an hour in the years since owning them. Did I fail at break in protocol?
I anticipate feedback recommendations of connect and enjoy the music after leaving them on for a couple of weeks at my normal listening levels, which has served me well in the past.
