1335d1338245049 why do my 288 8ks sound like cr40p 288 1005

Oh yeh, that misfit . I remember now . Obviously, that was as good as it got , right ?? ( Mind-you , looks great up to 8K )

It's seeing curves like that really damp-down my enthusiasm for acquiring new GPA diaphragms ( since the cause of that suckout is still not determined ) .

( Maybe it's a function of the 1005H horn loading on the driver/phragm combo ).

Did you ever try to fitup one of ABs diaphragms into your driver, as a "yardstick" reference ?
