How can compact siren speakers project as far as reentrant exponentiahorn speakers whose sound path is much more gradual in diameter and longer?
Does the gradually-increasing sound path diameter couple the sound energy to air better?
Has anyone done tests to measure the dB output from different speakers withe same wattage input?
Is the old, bulky Federal Signal CP100 "bullet" speaker withe longest cone and bell the most efficient and therefore loudest?
(Had one fall from the roof of our fire truck as we.retuning from a brush fire along a washboardirt road.
It had been attached to the roof with three sheet metal screws,I recall.)
Thank you
