This came closer than anything I've ever heard. The only thing that gave away
the fact that I was listening to a reproduction of a live event and not the
event itself (from a listening perspective only, of course) were the
trumpets. For the most part, the Wilson Alexandria XLFs produced, in that
large ballroom, all the power and dynamic contrasts of the real thing. I've
NEVER heard that before. Like I said, the trumpets gave it away as merely
reproduction. They didn't sound live, just nearly so. Trumpets are pretty
nigh impossible to get right. They are usually the difference between real
and reproduced. Most instruments produce very weak harmonic above about 8KHz,
and therefore the highly attenuated harmonics of those instruments are fairly
easy for a good speaker system to reproduce. But if the harmonics are strong
(a trumpet has harmonics that are equally as strong as the fundamental all
the way up to 16 KHz or so) the small 1-2 " tweeters employed by practically
all speaker systems simply cannot produce these harmonics at the volume with
which they occur live. This tells almost any listener whether a trumpet is
reproduced or live. Tweeters just can't move the volume of air that a human
of trumpet player can, and the difference cane be easily heard.


I take it you are saying that the tweeters were actually being overdriven,
and could not reproduce the peaks. Correct assumption?
