this is series-parallel, right?

    wiring.


    a friend sent me this photo. he has an amp wired up this way. I'm certain it's series-parallel, but I just want to double check myself to make sure he doesn't blow his head. it's a cab wired like this loaded with 8ohm speakers. this cab is rated for 8ohms, correct?

    You have two pairs of speaker in series and then the two pairs in parallel.

    What is each speaker rated?

    If each speaker is 8 ohms, then the two in series are 16 ohms, so the two 16 ohm pairs in parallel are 8 ohms.
     
  4. Two speakers in series, parallel to a second set of two speakers in series.

    Total impedance is:

    Z[SUB]Total[/SUB]=1/([1/[Z[SUB]1[/SUB]+Z[SUB]2[/SUB]]]+[1/[Z[SUB]3[/SUB]+Z[SUB]4[/SUB]]])

    8 Ohms, correct.

    8+8=16 (series)
    8+8=16 (series)
    1/16+1/16=1/8 (parallel)
