Look up Speltz Zero Autoformer. It's like a gearbox for your system, allowing you to step down the amp output impedance (or step up the speaker input impedance, depending on your viewpoint) without wasting all that power as heat.
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!!
