I need help understanding class D heads. I play in a very loud, very distortion-bassed (ha.) post-hardcore band, and I've been recently looking at upgrading my rig due to us wanting to start touring within the next 6 months. In these searches I've come across class D heads, and they seem very attractive due to both the light weight and high wattage. Now, this is where I get confused. Can a simple class D power say, a 4x10 and a 1x15 cab AND still be used at large venues? What are the pros and cons? Will they last to the rigorous life style of touring? If I can avoid having to lug a 150 pound head, that'd be appreciated. Thanks! - Cody Constantine.
