From the looks of that response curve, I'd still say there's something wrong. I hate to say it but my guess is the 2226 cones aren't genuine JBL. I see that pretty often in reconed JBL drivers. With good parts, the region between 500Hz and 1kHz is full and doesn't droop. In fact, since directivity increases, the on-axis output at 1kHz is actually slightly higher than it is at 500Hz.
