Actually there are mathmatic formulas for compression ratios in horns. Its part of a method of improving the acoustic coupling. Remember a speaker is an acoustic transducer. Its function is to change electric signal into auditory waves. The better it is couple to the air the greater the performance.mykey- wrote: ....another thing! not read much into these, but, I always look at things in a super practical way.....the way these drivers are loaded (firing through a small hole that's way smaller than the cone it's self) completely goes against the grain of things. How can you expect all the sound waves from the cone to get out in a ORDERLY fashion? the sound is going to be bouncing back and forth like a cosha Jews head in prayer
Accordinding to Wikipedia not all gasses respond the same to different frequencies. I The cause is different than I thought, but the efect remains.Tony Wilkes wrote: For all intents and purposes the speed of sound through air is a constant at ALL audible frequencies. What tiny tiny differences that do exist are of absolutely no relevance.
As Aunty Cilla has stated if anyone has evidence to the contrary please quote the source. Don't just argue for arguments sake.

Excellent point Tony ! Sorry I failed to account for that in my analogy. In fact as tired as I am right now I don't seem to be able to come up with a good analogy that also accounts for throw.Tony.A.S.S. wrote: Regarding the last part of Bobby Mosley's piece, it should also be remembered that what we term as throw, has a part to play in this. The Bugle, being a horn structured instrument will project further due to the horn and the way the note is started from source. Whereas the violin is only able to radiate sound around its own sound box, and the notes have a much more gentle start to life.
