I'm getting ready to finally buy a "pro rig" after years of combo'in it. But I'm confused as hell as to what exactly will work best. I've pretty much decided on generally what I want. I want to get an SWR Goliath III 4x10 and a son of bertha 1x15. I'm planning on getting the 8 ohm version of both because, to clarify, if I run them both through the same amp they will be running at 4 ohms, correct?? But now I'm not too sure what amp to get, I want either a GK 700rb II or 1001rb II, I know the 1001rb puts out 700 watts at 4 ohms, which as far as I understand might not be ideal because it will push the crap out of my cabs and give me 0 headroom, and basically torture the 115. But I don't know if the 700rb is going to be quite enough for what I'm wanting. Also, does anyone know if there's a way to set the amp to run at 4 or 8 ohms, and if so, how? Any input of any kind, even just your reviews of such a rig, is very welcome. Thanks!
