4 or 8 ohm with both 2 speaker cables?

    just traded my Ampeg PR410HLF for an Eden D410XLT. Before I left to go pick it up he told me it was 4 ohm which is what I wanted.

    When I got there the back of the D410XLT said 8 ohm. He told me that it is a 4 or 8 ohm depending how you hook it up. What he said was that if I only use 1 speaker cable it is 8 ohm but if I run 2 speaker cables out of my amp to both speaker inputs then it is 4 ohm. He said to think of it like hooking up 2 8 ohm 210's.

    Does this sound right?

    No, it does not sound right. The only way that would work is if the speakers were actually wired such that they were two separate 2x10's. However, I do not believe that this is the case with the D410XLT -- I believe that the speaker connections on the back are wired in parallel. The the easy way to check is to plug into one of the inputs and see if sound comes out of just two or all four speakers. If it comes out of all four, then it's just an 8-ohm cab as I suspect.

    If it comes out of two, then switch to the other jack and see if it comes out of the other two. If it does, then it is indeed two 210's. If this is the case, you will probably want to measure the DC resistance of each 2x10 to ensure that they're actually 8-ohms each (the meter will read something like 6 ohms).

    do not do this! he is a idiot....the only way to make an 8ohm a 4 ohm is to replace the speakers, although you can rewire an 8 ohm 410xlt to be a 2 ohm cabinet as it is 4x8ohm drives

    No. The two jacks are parallel connections. He's either BS'ing you or he's clueless.

    I am a little pissed right now because I hauled my 10 ton ampeg back to them and refuse to keep hauling cabinets back and forth due to their stupidity.

    sounds like he made it up and does not know what he is talking about and assumed he could pull it over on you...you definitly want the 4 ohm if you are replacing the 4ohm PR...i would definitly take it back and either tell them to give you the cab you agreed upon or your PR back...
