rePhase Crossover roll offs 4 years 1 month ago #25975

Hi guys,

Does rePhase take into account the measured natural roll off of a driver when implementing it's crossover roll off? For example, if a driver had a 6dB/octave roll off from a given frequency and you wanted a 12dB/octave crossover slope, will rePhase simply augment the existing roll off slope, or will it blindly add to it, in this case resulting in an 18dB/octave roll off?

Hello,

Everything is manual in rePhase, so the natural roll offs have to be taken into account by the user when making the correction.
To do so you need to import an actual measurement and work from there.
The easiest way to obtain a given acoustical filter is to first shoot for a flat magnitude and phase response, and then apply an electrical filter corresponding to your acoustical target.
You can use minimum-phase EQs to do so, but rePhase also provides a convenient tool to help directly compensate roll offs and other natural filters: the "compensate" mode in the minimum-phase EQ tab.
