Out of all Axiom's speakers, the M22ti, M60ti, and M80ti are the cleanest sounding. Since the M80s are out of your budget range, we'll not talk about those.
If you don't have a subwoofer and don't plan on buying one in the near future, you should definitely consider the M60s since they go much lower than the M22tis. It has been described that everything that's good about the M22ti, the M60s do one step better: wider soundstage, more precise imaging, and of course more bass.
If you already have a good subwoofer, then the M22tis could still be a great option for you. How large is your room, by the way? That can have a big impact on what speakers you decide to get. M22tis might not be the best option in a large room, and the M60s might not be the best for a small room.
