For the first time I'm experimenting with adding a subwoofer to my mains.
Mains: Dynaudio Contour 20
Manufacturer Specs: https://www.dynaudio.com/home-audio/contour/contour-20#tech-specs
Stereophile Measurements: https://www.stereophile.com/content/dynaudio-contour-20-loudspeaker-measurements
Subwoofer: M&K MX-700 (15+ years old, had it sitting in the garage)
2 x 8" drivers, push pull
Setup:
I'm currently doing all the crossover duties inside the Devialet Expert 400 using its built-in DSP.
Subwoofer is set to bypass, gain is set to Reference / 0 dB.
High Pass for Mains: 70 Hz, 2nd order
Low Pass for Subs: 70 Hz, 2nd order
I set this rather arbitrarily at one seemed to be a common sense starting point and it seems okay....not quite seamless, but not boomy or overpowering.
Questions:
1. What slope is best to use for both high and low pass?
2. Should I use a shallower rolloff on the mains high pass than the subs low pass?
3. Is there a better way of determining the crossover point than my seat of the pants guesstimate?
4. What's the best way to set the level? (I more or less just did it by ear)
