@kota1: thanks for your comment.
here are the center channel speaker options from the same company (GoldenEar) as the one who makes my front left and front right speakers.
any thoughts from any good folks here would be most appreciated. as GoldenEar uses ribbon tweeters, their dispersion is limited. I’m wondering if using a center channel speaker made by another manufacturer might work well too? i mention that because GoldenEar speakers all use a ribbon tweeter, and as such, they have limited dispersion, which is important for the center speaker. can using another company’s center channel speaker with, for example, a dome tweeter be actually a benefit?
thank you all in advance. look forward to hearing your thoughts!
