    With all the holidays and what not around, many of us are looking for new rigs - including me ;)

    Anyways, I'm currently running a Behringer BX3000T (300@4ohms) through a Hartke VX115 (300@8ohms). I know what your thinking - grosssss. But hey, when I first got it a while back, I got a great deal on both of them, and they've given me quite good mileage and *alright* sound with the money I paid.

    Anyways, I've been doing my research, and I'm looking to upgrade to a Kustom Groove Bass (1200@2ohms, 750@4ohms, 450@8ohms) head, and a new cab almost immediately/soon thereafter.

    My situation - I'll be running it at 8ohms through my Hartke at first (looking forward to my own non-Behringer sound, and a bit more power due to no ohm mismatch for below 300 watts). Then, I'm looking to upgrade to an Avatar 210 Kappa Pro, 4 ohms. That'd leave me running at 2.67 ohms, somewhere between 750-1200 watts - leaving still plenty headroom on the avatar, but pushing the Hartke a little perhaps. I'm doing this not because I'm a watt-hungry headbanging hard rock metalhead, but because I prefer the headroom and don't want to push my amps, and leaves me with open options depending on where my band(s) are going.

    Bottom line - running at 2.67 through those 2 cabs should not pose much threat, provided I'm not stupid with the knobs, correct?

    If anyone wants to point me to anywhere to a thorough guide to anything relative to this or has any suggestions, I'm open to those to.
    Thanks in advance :)

    the 210 cab will get most of the power. I've done a setup similiar before, a 210 peavey(4 ohm) and a 410 eden(8 ohm), and personally I didn't like it because one cab was so much louder than the other it just seemed pointless.
  3. The 8 ohm cab will get half the power compared the 4 ohm cab. Say you're getting around 1000 W at 2.67 ohms, the 8 ohm would get 333W and the 4 ohm cab would get 666W. So as long as the cab's power ratings are reasonably close to that same ratio, neither cab is in much danger of blowing before the other. Be sure to keep holy water nearby for the cab getting 666W. Mark of the devil and all.
