I disagree. This is one case where a matching center is a horrible idea. The VCS10 is terrible speaker...I used to be a Bose fanboy and had this speaker. I could deal with the bass module and put up with the tinny sound of the cubes (for WAF sake), but this speaker killed the whole setup for me.
I don't think there is anything out there that would sonically match the 161s, but I would definitely try the Polk CS20 before going back to the VCS10. Energy RC Mini, Infinity, DefTech Pro Center 1000, can all be had around or under the same price point as the VCS10. Miles ahead in performance, too.
Nothing like doom metal in the morning to get you going
