That is what is called a neutral speaker when all the sounds are in the proper place/together etc.
You should get a cleaner sound as the volume goes up by adding the amp, which in turn will give you more feel of the midrange and highs. I would say punch as that is usually for midbass and the small M22's are not capable of much punch and the sub is too busy looking after the lower end for effective punch as well. A good tower with lots of power behind it and the right room with no 50-60hz nulls would work well for some good chest punch bass.
