Nice write-up @cohicks4 , but I’m a little confused:
Even though the midrange and tweeters look like horns they are actually compression drivers with horns for dispersion
Most horn mids and tweets I know of ARE compression drivers. I think you may be thinking of horn loaded bass cabinets as a "true" horn speaker, but in my experience, both are considered true horn speakers. Just different drivers attached.
I wouldn’t say "even though ... look like horns..." because they really are horn speakers. If they lacked the compression driver they might be called "wave guides" instead, but potato potatoe.
Using compression drivers attached to a horn is 100% pro horn speaker construction. Nothing illegitimate about it.
