i may be able to get an avatar cab and wondering which would be a better standalone choice, the 4x10 or 2x12. im leaning towards the 4x10 because of its higher wattage but i dont know about it handling the low b on my sr5. anyone with experience? since im going standalone, i should get the 4ohm version right? is the line-x worth it? i want to get something solid that would last me a while. im in a jazz choir right now and looking for a hardcore or metal -type band to play in in the future so ill need some volume later on.
