  • Need wiring diagram to wire five 8ohm speakers

    Need wiring diagram to wire five 8ohm speakers prefer I end up with 4ohm or 8ohm, I already know if I were wiring 6 drivers I could end up at 5.3 ohm , but bassbox is no help trying to figure out wiring 5 drivers , hope this is possible to do. ?

    With 5 drivers you will either end up with a 1.6 Ohm load when wired in Parallel, or a 40 Ohm load when wired in series.

    Parallel is basically just tying all the negative speaker terminals together and connecting to the amp (-), and all the positive speaker terminals to the amp (+). It's likely too low of a load for almost any amp... and 1.6 Ohms isn't really a true figure, it will likely be lower than that in reality -- probably closer to 1.2-1.3 Ohms as a rough guess.

    Series will have too much resistance, that won't work at all, you won't hear the music much over a whisper....

    Odd numbers of drivers are a problem unless they are manufactured on purpose to be used in odd multiples with appropriate voice coil ohm figures.

      By the way, if you have Bass Box Pro, you can see a wiring diagram for 5 drivers or any amount really... go to "Driver" tab, then go to "Configuration" and type in the number of drivers you want, and it will show you the wiring config below.

      If you then go and plot the graph for 'Impedance' and go to the "Parameters" tab right next to it, it shows the results of your chosen wiring configuration in the "Net" column to the right. I did this by only adding the driver Ohm figure as 8 Ohms for Z and 6 ohms for Re, a guess, but probably close enough to show the expected results.

        It is not. That's why you don't see an odd number of drivers being used, other than nine drivers, which can be wired to end up with the same impedance as one.

                  If ONLY they were 32 ohm drivers ( or at least 20 ohms )

                    I would like to see the same type diagram for 4 drivers 6 drivers 8 drivers etc etc , will look around for some. Thanks again that was a big help

                      It might be faster to learn Ohms Law

                      What the 9 speaker scheme shows is an example of a N x N Matrix, that maintained the same resistive/impedance value as an individual element ( where N = 3. A 2 x 2 matrix for 4 speakers, a 1 x 1 for 2 speakers. ) Carry that out to N = 4 for 16 speakers, N = 5 for 25...
                      This is of course just one example of a Matrix series, that can all be simplified with Ohms Law on Resistance.

                          Seems like you* could wire 4 in series parallel, that being 8 ohms than parallel the 5th driver to it for 4 ohm total?*
                          The group being 8 ohms and the single driver being 8 ohm it seems like everybody would get the same*
                          power.
                          Guess xmax's age.

                          My guess: 15. His grammar is passable. His trolling is good.

                            The group of four would get half the power, as would the 5th, but only until the 5th was blown.
