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?

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.
