I have two pairs of speakers that could do with opening them up to investigate problems--one decades-old set of Celestion hi-fi speakers that has developed a rattle, the other a set of M-Audio Studidophile SP-5B powered monitors that needs a replacement LED power indicator.
My question: I've heard that the mere act of opening a speaker cabinet can change the sound of a speaker. Is this true? If so, how does one open speakers to service them while countering this problem?
Or is this something I don't need to worry about?
