Greets!
Understood, and what you say is true as far as it goes, but you've come to an erroneous conclusion based on insufficient information. If you do the research on the models I listed you'll find that Altec listed the 288/300 Hz combo on these horns and if you study compression driver design and do some PWT measurements you'll see why they will perform at rated power at XO points much lower than 300 Hz IF the horn lens is designed to support it. Consider that the 'grandaddy' of these drivers is the 1" W.E. 555, which when loaded with the 15A lens has a full power BW of 100-5 kHz, and if someone wanted to make an even bigger lens it could be lowered considerably.
