Sorry if this has been asked by searching was giving me nothing about specifics. I'd like to have a setup with two 4x10s in which I can use one or both of them. However, getting an amp powerful enough to drive both would be too powerful to run only one. For example, the 4x10s would be 500W and the head would be 1000W. No if this is acceptable because I'm misunderstanding all this stuff than the rest of this message is moot. The options I see are: 1) Something like the Hartke LH1000 which can has the option of two 500W channels or one bridged 1000W. Although this doesn't seem to be a common option so I'm skeptical of it. 2) A stereo powered amp with a preamp. 3) The GK series with the powered MBP cab. Nice idea but the most expensive of the options. 4) Two combo amps since I already have one. Although, it's only 200W. Seems like the weirdest and most inconvenient. Right now I'm leaning towards the stereo powered amp like a Crown XLS 1500 because of the added bonus of having a back up channel for monitors or worse case scenario putting the PA into the main PA if there's a hardware failure and just running direct through the PA. The other option I was considering since I have the Acoustic B200, which I love regardless of its cheapness, is to get the Acoustic 800W stack. However, it looks like the head is built into that case and if I'm going to get a rack then I want to be able to hook it up with other things like a tuner, power conditioner, etc in one case. Anyone know if the Acoustic head can be easily removed from the case it comes in?
