Is doubling speakers +3dB or +6dB? What’s parallel and series wiring?

Devin demonstrates the differences between parallel and series wiring and answers the age-old question about whether doubling speakers adds 3dB or 6dB, with a close look at what happens in real-time with the voltage and current output from the amp as the frequency and speaker impedance changes. Special thanks to all those who fact checked me on this. I am amazed at how many incredibly brilliant people follow my videos and are willing to help iron things out. Sorry to the crowd who thinks voltage should always be represented by V (including ChatGPT), you lost this one. Also, for those wondering, the NXampmkii was on the “FLAT“ setting. The test mic was a DBX RTA-M going into a Rio1608-D. Softwares included Logic Pro X, Signal Scope X, DATS, and Dante Via.
