Re: Extended High End on Compression Drivers
The built-in CD equalization in the Behringer crossover (and other active crossovers) is intended to do the same thing as the top-octave compensation in my passive crossovers. So just switch it in when using a horn that needs it.The horn isn't actually wh...
