JBL Synthesis SAM3VA Xover schematics and measurements

[old-fashioned]

Hi!

I´ve bought used JBL Synthesis 3x SAM3VA and 2x S2S for less than 1400 Euro.
Now I´m a little bit confused, because the measured frequency response curve is very different above 4kHz compared to the JBL spec sheet.
Especially the brilliance is noticeably too loud. It´s even obvious in the measurement sweep.
Are there any crossover schematics and separate driver measurements available?
(maybe the responsible JBL engineer can contact me directly... )

Best regards from Germany,

Andreas
