    What do you guys think about putting the Hartke 3500 with the Ampeg SVT-410HLF cab? the ampeg cab is 4 ohms, so if i added a 15" cab to the mix, how many ohms should the 15" cab be? Thanks
  2. No can do. The 4ohm cab is all she can handle. Adding another cab of any impedance will put you below the manufacurer's limit.

    Yea, But I_am_Rage uses the hartke 3500 with a 410 and a 115. They are both 8 ohms, but isnt this going under the limit.

    i see why a 4 ohm and an 8 ohm cab mixed would not work....but two 4 ohm cabs would not work?

    Asking this states that you don't know the answer as to why any combination works. You must study ohms law, and understand the way resistance and impedence work.

    a 4 and 8 ohm cab together equate to a 2.6 (repeating) ohm load. An 8 & 8 makes 4, and 2 4's make 2.

    That is what you wanted to know.
