I know from your earlier post that you are already pinching on driver spacing with 8, but you can have the ninth driver fire up or fire to one side or even to the rear. That would look like this in the calculator link : 8-8-8. Of course, this would also reduce the Max SPL. Wire 3 sets of 3 in series, then wire these 3 sets in parallel. However, 2/3 of the voltage would appear across the single Speaker and 1/3 of the voltage across EACH of the two Paralleled Speakers.hence for 1-V rms from Amp (and using P = V^2 / R), the Electrical Power Input to the single Speaker would be 55.6 mW and 13.9 mW would be Power Input to EACH of the Paralleled aning that EACH of them would be at a 6 dB LOWER SOUND PRESSURE LEVEL.ģ) Alternatively, you COULD ADD one more 8-ohm Speaker (hopefully same P/N so they are truly MATCHED) in a Series/Parallel configuration [One Paralleled Pair of Speakers is in Series with another Paralleled Pair of Speakers), so that TOTAL = 8-ohms.and they ALL have SAME Power Input.and can "suck" more current out of your Amp, providing Max SPL compared to other alternatives.Ĥ) Alternatively, you COULD simply DISCONNECT one of the Speakers, so when the remaining Two are Paralleled, Total = 4-ohms. Ģ) If you were to wire one 8-ohm Speaker in SERIES with TWO Paralleled Speakers, then the Total = 12-ohms. 1) For EQUAL Power from all three speakers, you would need to wire them all in SERIES, for a total of 24-ohms (NOT a problem for Amplifiers).although this would NOT provide anywhere near Max SPL of other alternatives.
