RE: Maggie MG-20 crossover questions

I would leave the modules alone for the time being. What needs to be adjusted is the gain. The goal is to have both amplifiers producing the same gain. So if the bass amp has a gain of 28 dB and the treble is 24 dB, you need to compensate by adding 4 dB to the treble (or reduce the bass by 2 dB and increase the treble by 2 dB - you get the idea). The sensitivity of the amplifier is not the same as gain and sometimes the manufacturer will list the sensitivity but not the gain. To convert sensitivity to gain:
gain = 20*log(sqrt(8*Max Watt)/sens)) Note: Sensitivity is the input voltage that produces the rated wattage with an 8 ohm load.
