thanks for the info. pdq.

A church I used to belong to ordered a new sound system. Included were two extremely impressive-looking speakers, about 10 or 12 feet high but very slim in profile. Once installed, they have very little impact on the appearance of the church. I believe they came from Norway.

That sound system does an excellent job, but I'm sure we don't have the money for something like that.

Interesting note: close to the scheduled arrival date, the church was told there would be a delay. It turned out that ATF was suspicious of the long, thin wooden shipping crates from Norway with many, many screws. The speakers weren't sent on their way until it was verified that they were not guided missiles or something.

Question - if a mic is adjusted for a speaker and the speaker gets very intense and talks an octave or a fifth higher, how much higher is the energy load on a listener's ear?
