Default high frequencie tweeters 50khz

If u look around, you soon notice that most speakers try and achieve 20 -20000hz. yet why is it that a lot of amplifiers can go from around 10-50000hz. Are there speakers out there that can go these extra frequencies. If so are there speakers suitable to be run off a power amp? Thanks
Daniel

The latest Tannoy supertweeters can go this high. Most good quality ribbon tweeters and electrostatics can also go this high. Whether or not we can hear these frequencies is still up for debate. Some people claim they can hear them, some people say that it has been scientifically "proven" that the human ear can't hear them. Either way, it's pretty cool.

In my experience, the higher frequncies seem to add spaciousness and a more "real" feeling to live recordings. I may not be able to hear sine waves up that high, but having those upper harmonics does seen to involve me more emotionally in what I'm hearing.

Just my 2 cents.

Cheers,
Zach

Default hearing , 20-20,000hz, - i Dont think so..

Had a bit of play around with signal generator, hear easily up to 25khz, seems the cd players dont really cut it do they?

i`ve found ribbon tweeters than can extend above 25khz to give a sense of spaciousness and air as what usekgb said. to if we can hear it or not... i really don`t know

A nice but extremely expensive supertweeter is this one:

I remember reading something published many years ago that stated humans can perceive some ultrasonic frequencies when immersed in a complex acoustic environment.

In other words, single tone tests aren't entirely accurate. When listening music, humans can hear something above what is considered normal.

I assume the people who conducted this study had data which supported it. Either way, it is interesting to consider.

Though it gave no explanation, I theorized that perhaps it has to do with the mechanical nature of the eardrum. Perhaps once the eardrum is already moving from something complex like music, it is easier for higher frequencies to excite the eardrum.

If you're listening to a CD, the high frequency rolloff is rediculously sharp above 20kHz, so extra bandwidth from a speaker may not make a difference anyway.

I have a pair of these, and they're worth every penny,
but I have to say that I have talked to people who disagree.

Dr. Bruce Dear has done some research indicating that bats
can in fact sense information at frequencies much higher than
their ears seem to physically capable. I'm sure you can Google
his paper(s) up.
