Bose 802

Talking to one of our assistant ministers today, and he pointed out that one of our speakers (Bose 802s) rattles or distorts at certain frequencies. I haven't actually noticed it, which means it's probably one of the left drivers of the speaker, which point away from the mixing position, and as he said it only happens at certain frequencies and then only when the keys play a certain couple of chords. It sounded to me like a proken driver, and when I rang up the guy we purchased them from he said the same thing. So know i have to pull it down and have a look at it.
yay.
