Thanks!
Dave, thanks for responding.

I am looking for the lowest profile Horizon center that doesn’t affect the performance. My towers are black satin bamboo, with RAAL. But if you recommend the original size, your expertise I will trust. Also, do you recommend keeping the RAAL tweeters with the surrounds?
