As of recently I've been looking for a new job and have decided that once I get some money saved up I want to invest in a newer, nicer speaker cabinet. I run my AD200B through a sealed 2x12 guitar cab with Eminence Deltas in it and it gives me that gnarly, woofy, Butler/Bruce tone I've searched for forever. Everything about the sound is awesome except for the fact that the cab is sorta less than efficient and has a little bit of rattle to it. At the same time, I have met with a new guitar player recently with a 100 watt full stack that will be played against me. Said guitar player friend is also personal friends with Casey Yarborough of Order Of The Owl. (An awesome band if you've never heard of them!) we discussed recently how their bass player runs bass through a Thunderverb 200 with a standard 240 watt Orange 4x12 with the stock speakers. Casey stated "If you want to run your AD200 through the 240 watt cab, there shouldn't be any problem." But I am still very concerned about blowing speakers. I am under the impression that regardless of how much higher the wattage is, guitar speakers won't be able to withstand bass. Thoughts? Orange also makes a higher powered version of the same 4x12 at 400 watts. Is this the best option?
