I entered those settings for the 708's & 705s into my Q-SYS dsp and there was a significant improvement in the cohesiveness between them and the M2s when compared to the PEQ's that have been floating around on the web. It appears that JBL omitted the input filters from the DCIn amps probably due to DSP resources. Maybe the reason why they locked the files so that enthusiasts couldn't compare them.
I probably should load those PEQ filters for the M2 into Q-SYS and do some A/B comparison between the FIR filters.
