I can't really speak to the voice matching question as I only have the Beta C360 in anything fairly current in Infinity, or anything current at all as far as speakers go.

But i can say that I'm happy with it for a center channel speaker.

I find it ample and smooth enough, but I do the old studio monitor trick with it of hanging a sheet of TP over the tweeter (and squawker in this case). I also EQd out some mid bass. I'm attempting to voice match it to some old Pioneer monitors that had "graphite modulus" Lo and Mid (very fragile) and ribbon tweeters. I haven't run Smaart on it yet, but this seemes like the most transparent compromise to me. I always take the challenge to do it by ear first before bringing out the analytical instruments. After the analyzer, I'll do the ear tests again, then analyse, ear, back and forth.

Sorry I can't be more help to the point of your question. But I'm finding it a worthy center channel.
