Hello!

I have a pair of JBL 4770 with 2 x 2226H + 2445J + 2380A. I biamp them and can use JBL DSC260A or a Dbx Driverack PA. But I need the compensation for the 2380 horn to get it right. Anyone of you nice people have it?

Take a look in the M552 maunal. It's unity at 5k -4dB@ 2K and +6dB@ 20K. That's a general family curve. You may have to tweek it a bit.
