4670D

[Sam]

Hello!

I have a pair of JBL's similar to JBL 4670D with 2 x 2226 + 2445J + 2380A. My problem is that I haven't found the right settings or tunings for the 2380, or the 4670D. I have only find for the 4675C. I will biamp them using JBL DSC260A or Dbx Driverack PA. Do you know were I can find it?

Best regards
Anders

The new Everest looks great!!!

Recommended crossover is 800hz, with HF compensation added for the CD 2380. In terms of what the passive crossover uses, see if you can find the curves for the 3110A crossover, or put the inverse curve of the un-EQ'd on-axis response in the tech doc: http://www.jblpro.com/pages/pub/components/2380a.pdf. I also know I've seen the HF compensation listed in various threads/papers here.
