Well, opinions and experiences vary, the ringing is the fundamental issue. Many folks do feel that the 511 does OK as long as its not used anywhere near 500 Hz. I think crossed at 1 kHz, they're OK.Could you elaborate on what was wrong with the 511 horn? Just curious because that's the horns I have. I know they have issues with the walls of the horn "ringing" if not damped (which is what I have done). They were made light because, if heavier, they would be more difficult to move and rig in a typical commercial installation. With the 1/2" Aquaplas / Bondo coating on mine, they are damn heavy.
My favorite 511B discussion, which led me, inexorably, to the WE/Altec 32 family and the EMILAR EH-500-2 (the latter being my current treble horn) was at AA a while back (FWIW... and way off topic for this forum!):

An instant master class on the 32 horn family (with a little EMILAR thrown in, too)
