I have a VP100 center with a pair of M3Ti sides, and a Hsu TN1220 sub. I found that I could get the sound somewhat tinny out of the VP100 when I did both of the following: 1) I put the center gain too high in my receiver; and 2) the VP100 was wrong way up sitting on a coffee table with the drivers pointing at a hard, reflective surface. So if you have adequate bass in the rest of your setup, I'd look at receiver settings and placement. Reflective surfaces can make any speaker sound poor. Good luck!
