How long it take to run in brand new loudspeaker?


I just bought a pair of QUAD 11L Bookshelf and found that the high is bit soft, is that due to insufficient run-in?

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.
