i am dating myself here but, then again i'm a dinosaur. going back to the late 70's we used to use the scoop (lot's of them) mainly because choices were limited and they were the suggested mate for the 4560.
for P.A. we complained that there was no throw until someone decided that laying them on their sides in pairs end to end with the woofers alinged together and the scoop ends opposite formed a perfect folded horn with drivers coupled. we would mount 8 singles per side, (4 high sideways) TALK ABOUT PUNCH AND THROW!
