My first impression, as TomTuttle said, is that 16 ft. is a LONG way from the TV. How big a screen do you have? You might have more of a video issue than an audio issue.

My room is slightly smaller than yours at 16 x 20. I found the M22/VP100 combination to be more than adequate at normal listening levels. Unfortunately, I contracted a case of upgradeitis and now have M60s. They fill the room quite a bit better than the M22s, but you definitely won't be disappointed with your choice.

I started out with nothing & I've still got most of it left
