For amplified live music ATC is hard to beat. They're better at high volume.
They also manage bass better than most brands. This is one of those things that you need to experience and live with long enough to stop being emotional about it. ATCs start rolling off bass at a relatively high frequency. This very significantly reduces room problems, especially when you crank 'em up a bit. They provide fantastic dynamics, very high quality bass. The bigger ones with big bass drivers have great punch. And you can fill in the very low end with subs if you want. Mains with -3db points below 40hz are a bad idea in most rooms for amplified, bassy music..
