Im trying to wire some bass shakers on one single line for the amp and I have 3 of them. Two are the same earthquake mqb1 and the last is a buttkicker lfe.
The mqb1's are showing me a 5.3ohm when I test them and the buttkicker is 3.8.
I found an online calculator about doing 2 in parallel and 1 series that keeps the ohm level at 6.45 with the majority of the power going to the buttkicker wish is what I want.
Is this diagram correct?
Has anybody else ran 3 speakers together like this before?
Im assuming also that once I come off the rca to my dsp that I have to tune that whole channel as one? I cant split off that signal and control them individually?

Should work ok, if the differing driver levels work out acceptably. Drivers on the same channel
are all tuned together, since there's no way to separate them out.
There will be some interaction between the different drivers since their impedance curves
are not the same shape, so check carefully whether that will be acceptable.

You can use conventional passive crossover techniques to tailor the individual responses.
Firstly considering that when designing this as a whole the units are going to get a certain share of the power, will have varying sensitivities both naturally and within this combination, will have different responses, will as rayma states, divide the drive signal according to their relative impedances.
Thats true I could always attach crossovers in line for what I want. But I think it will be ok having them run the same crossover. The Bk dies off after 25hz and the earthquakes takes over 20-45. Ill test it out and see how it works out. I can always put the earthquakes on these two other amps I have at 150 rms each but not sure I want to run 3 amps for all that stuff. Id rather give them more power anyway also.
