Tried a little experiment at my last gig and ran my Ampeg Portabass 250 head into my 2 BagEnd S-15D cabs. I must say that I was extremely impressed with the result. I was not cranked all the way up. I know this because the limiter never kicked in. Great thing was that this rig was very easy to transport. I'm not sure that I'm ready to sell of my SoundTech PS802 amp yet though. That power amp has served me well for 2 years. I'm not thrilled with the thought of sending it away.
