"Crossover Design for New Project"

Are you sure they aren't FRs of the same driver ( but at a different axial point ) ?
- It wouldn't be the first time that a "cataloging malfunction" muddied the waters .

I could always measure them again while I got the test gear set-up.As I'm doing the off axis of the T350's I could measure the 511/288's again
