The problem is that the punch in your chest is not from your sub, it is usually from the mains and as you have M22's it won't happen. The chest thing is said to be around 60 -90hz and the sub is busy playing ALL low frequncies and smoothly. If you want to feel it in your chest you need to try to optimize the frequency response for around 60-80hz. I have seen this question many times, check out MikeC on AVS, he bought MANY subs looking for that chest thump only to find out he was searching in the wrong frequency range. You could possibly benefit from Hsu and their
Mid Bass Module(MBM) System. . This was one reason I went to M80's, with them I get more impact than I did with M22's/sub.
