Yes...that's my point. The M22's really need to be paired with a good sub. Before I bought mine, I did a side-by-side with the Energy C-3's, and without a sub, I may very well have gone with the energy's, but I realized that I would be using a sub. So I did another listening session with the sub on. With that, there was no comparison. The M22's no longer sounded "thin". They were just clean and clear all the way through.

so...try your A/B test again vs. the 170's this time with a sub, and let us know what you think.

btw - your initial thoughts on the M22 vs the 170 are exactly how I felt as well. The M22's details are unrivaled.
