    I have a 4 ohm SWR goliath jr (2X10) and an 8 ohm goliath (4X10). I know that the combined ohm load is 2.6. So my ampeg B2R won't drive both cabinets. My question is if I go for a power amp (QSC, Crown etc)and pre amp (SVP, FX-1 etc.) and run it in stereo will the different ohm loads on each side be a problem? I figure I can balance the volume with the amp controls. I'm also considering a B5R as an option.

    Advice welcome!!! Thanks
  2. Bingo! Won't be a prob with a power amp. As you say adjust to differences in sensitivity and taste via power amp LR volume controls

    Yep most power amps nowdays go down to 2 ohms bridged or 4 ohms per side stereo. Can't hurt to check specs before you buy.

    You're right that the 4 ohm cab will recieve more watts that the 8 ohm, which is a shame in your case because it's also the smaller speaker cab. So you will indeed need to wind down the volume on that cab.
