What is the difference between these two models? The Eden website only gives info on the "C" series and the info Im reading on the "B" series from other websites is mixed. Mainly, I want to know if I can run two 8ohm cabinets off the bridged/mono mode on the "B" series model. Sometimes I read that you can run bridged into 4ohms for 1100watts and sometimes I read that 8ohms is the minimum load you can run off the bridged/mono option with the "B" series. ***??
