Thanks! I've been reading some articles and all of them recommend having a center speaker that is in the same manufacturer and model/series. I went for the Tannoy mercury VCI, instead. The tweeter can go up to 53khz (same with my fronts) compared to the Fusion which can only go up to 20khz.
The vocals really match with my fronts. The voice of Michael Buble is very well defined when playing music with "DD prologic II Music". I'm glad I went this route.
Thanks, again!
