If you combine four speakers by connecting two in parallel and two in series, you will end up with the total impedance equaling the impedance of a single speaker. You can see this by using this calculator and selecting "2 series and 2 parallel" and entering the correct impedance values. If you added a series resistor to increase impedance, it would have to be a power resistor able to dissipate the wasted power it would use in heat, and it would affect the sound. Hope that this helps!
Increase total Speaker Impedance Question
Hi All,
I got a tech question. I have built a pair of speaker using a unique crossover for each speaker. Based on my test, if I parallel wire them, the resulting frequencies are correct, but resulting frequencies are NOT correct when I tried to wire several speakers as a series (series-parallel wiring). I suspect that because series wiring requires daisy chaining two or more crossovers, the resulting frequencies are messed up. However, if I retain current parallel wiring, the total impedance of the speaker system is too low and the amplifier often goes into protection mode. Is there anyway to add a resistor in between the amp and the speaker to rectify the situation? And if I do add a resistor, will that affect the sound quality? Thanks!!
