I have narrowed down a few options for a center channel speaker. Currently my mains are arendal 1961 tower speakers. I didn’t include the 1961 center because it had some reviews that said it wasn’t as good. The next step is the arendal 1723 s and it’s also an mtm design but doesn’t fit. So my choices are svs evolution center, and either the rbh 661c-sf or the rbh 661c-sf/r. I know the rbh are not 3way but heard good reviews. It has the tweeter a bit higher than the drivers. The main difference between the rbh models is amt tweeter and better drivers. I can’t go any bigger than 8-1/2 inch tall. Heard good things about rbh. Kef r6 meta sounds good too but very expensive. Any help would be appreciated.
