    so, i've been thinking a bit...

    my Epifani UL502 has only one speakon output. if i plug an 8 ohm Epifani 1x12 into it, and then daisy change another 8 ohm 1x12 to the previous 1x12, how is that 4 ohms parallel? wouldnt this really be in 16 ohms series?

    a little confused. anyone care to give me the techie answer?

    Doing a little bit of research, seems like you have them in parallel. it looks like the speakons with two pairs of conductors (+1-1+2-2) are designed to supply two seperate circuits with power. so you would wire one cab to pair 1 and the other to pair 2. looking at their schematics, it looks like a parallel connection.

    this would explain why such a high wuality amp only has one speakon output.

    EDIT: it looks like you may need a Y splitter cable to split the two pairs into each cab.

    It's parallel, and it's 4 ohms. The way amps speaker cabs are wired, it's the same as if you had two speaker outs (on a mono amp) and plugged an 8-ohm cab into each one.

    thx guys,

    i'm guessing this only works w/ the speakon's?

    Did a bit more research, it seems amps with only one speakon out are like that because they are not designed for biamping. so youd only need one speakon to run the two cabs with the two pairs.

    amps like my 1001RB-II have two speakons because they are designed for biamping so two 4-pole speakons would be needed to biamp two cabs.
