I just picked up a used Avatar 212 at a local music store for $150! I'm not sure of the exact model, but it is rated at 4 ohms, has two 1/4" jacks and a tweeter attenuator. I am integrating it into my rig, it is replacing a Hartke 410XL. My new rig is SansAmp Bass Driver>BBE 462>Sunn Coliseum Slave>Avatar 212 & Joe's 115. I have not had a chance to put this through it's paces yet, but I am pleased with the initial results! I will post pics soon.
