So my system (very budget minded) will most likely consist of 2 x Fluance AV-F3 in the front, and 2 of the same in the rear (if my budget allows, I MIGHT get SM-938s for the fronts and use the AV-F3s as the rears). I'm puzzled on what to do for a center channel. Fluance's seperate offering doesnt look too enticing, and there's no other center offered in their product range. So, I need some ideas for a low cost, $150 at max center channel. So far my two thoughts are the Wharfedale Crystal Center or the Wharfedale Diamond 8 center. The first is poly like the woofers of the speakers, so it'd most likely be a better match for the sound. The second uses kevlar woofers, which would possibly be too different a response. However, I've always been told to pay attention to the center channel, because it's pretty much the most key speaker in the system.
So, will the Diamond 8 center be too much of a deviation in sound? Should I look at other centers, and if so, which ones?
