So, the other day I connected on parallel a dual-voice subwoofer-system (a Pyle XSUB1-150-4-12d crossover — like this one ... link might be unavailable after Aug 28, 2019 ... — and 2 individual subwoofers) with a 3-way-speaker-system (Weconic) and they sound good together! As far as I can hear with the help of a 7-band-equalizer (100Hz, 200Hz, 400Hz, 800Hz, 1.6kHz, 3.2kHz, 6.4kHz) there is no frequency not being reproduced and the 3-way-speaker seems to receive less of the waves with frequencies below — and arround — 100Hz than the "dual-voice-subwoofer". This is the "roll off point" of the XSUB1 crossover.
I wonder how the distribution happens... and have some doubts...
++ UPDATED ++ (based on the first 4 comments)
Does the XSUB1 crossover "pull" the frequencies below-and-around 100Hz? Or does it "block" the others >100Hz?
Or does the XSUB crossover-elememts absorb the frequencies I don't hear through the subwoofers? Are these transformed to heat or magnetic fields in the capacitor or coil? respectively?
Should I know more about what a crossover's "roll off point" does to the frequencies?
Sorry if my questions are pointing in different or vague directions and thanks for helping me know what happens to the information travelling!
++ EDIT ++
I have used components from several items:
two identical subwoofers
100Hz stereo crossover
Yamaha NS-G7's 3-way-crossover
It turns out the tweeter of these drivers is dead... so I can't give an Ohm value...
