Peak Boost Frequencies for EV Sentry & Interface Speaker EQ Boxes

[jorb]

Hello,

What are the 6 db Peak Boost Frequencies used in the Electro-Voice Equalizer Boxes, that are used with the below speaker systems?

Sentry III, 28hz or is it, 32hz
Sentry 500, 28hz or is it, 32hz
Interface A, 35hz or is it, 39hz
Interface B, 35hz
Interface C, 35hz
Interface D, 32hz

I am getting conflicting data on what Peak Boost Frequencies are used, in each of the Electro-Voice Equalizer Boxes.

Thanks,
