Revel center channel help. C-30, C-50 or Voice?

I would compare the C-50 to the voice. If you are going with studios I would be inclined to go with voice which is perfectly matched to the mains. I have the whole setup including the studios,voice, 4 embraces, and 2 subs 15s. I am planning on using a voice as a rear center some day.

I would not use an m20 for the center. I also have the M20s and the c-30 in another system and these work great together. There is a reason Revel built dedicated center voice speakers. You can email them and I suspect they will second this thought. The question for you is the choice of the voice vs. the c-50. I personally would match the voice with the studios. Although the c-50 might have advantages I am unaware of much as the B-15 had advantages over the sub-15, which was the original sub matched with the ultima line.

I have the M20s and agree that it would perform well as a center channel but don't understand why anyone would do it. You can't buy them separately and its not worthwhile to look for a damaged set to break up. The c30 series and above are designed for center and can be purchased one at a time. If you are using the F50 I think the c-50 or voice would be the best match. You might be able to get a good deal on the voice here used. I don't know whose centers the other contributor was using but I would never use them for mains even they should have similar sonic characteristics to normal mains. I can understand the problem he had.
