How long it take to run in brand new loudspeaker?

For me it has always been the bass to clear up last.My Aerial cc3 sounded like there was a comforter over it for 3 days,or more. I actually put one on it and ran it loud for 4days continuously. Then there is the Korus. A dealer in a phone conversation, said this speaker improves till it has 3,000 hrs on it.

Depends a lot on the system, of course. The Paradigm 100s in my HT set up needed 300 hours to settle in. OTOH, the Mezzo Utopias in my music room didn't change much from day one.

Seems like the best performance speaker will only have after 10...15 years of home usage and after a couple of years of heavy commercial usage.
Please, rub your head... 1000hours????????

I've only run in two pairs of high end speakers Sonus Faber Concertinos and ProAc Response 1SCs, and in both cases they sounded on the thin, tizzy side brand new. After a month or more of play, the midrange was more open, the treble relaxed yet still detailed and overall more liquid. Also soundstaging grew and center focus locked in better.

I have just confirmed that It is due to insufficient run-in. After 90hrs of usage, the baby quad produce highs so beautifully that you cannot believe it come from a budget speakers!

Tks.
