The Paragon horn design cutoff is about 50Hz But.. the LE 15 goes below 30Hz can I hear it? You bet your little cookies. But with some added distortion. Can I hear the difference in LE 15 & 150-4 with the paragon horn below cut off? SHURE. The woofer doesnt stop at horn cutoff but its amplitude is affected. Can I hear this? Yes. Its not the bottom end that I obssess about. Its the Poor high frequency spread over the curved panel ( 500Hz to 7000Hz) the rest (075) spits out at you out of that black mouth. Why didnt they aim the tweeter off that curved panel boggels my mind. They do it on the Metragon. They do it on the Minigon.
