I think you’re moving in the right direction using a monitor for a center. The best center speaker I heard for dispersion was a B&W Matrix center that consisted of a tweeter mounted above a single midwoof driver, so it was not unlike a standard monitor speaker in that regard. I wouldn’t use two monitors as centers as you’re likely to create more problems than it’s worth, and one monitor should be fine as long as it gets down to 50Hz or so I’d think. Love your mistress BTW. Nicely done!
Left center and right center speakers
I am running a 7.3.4 Dolby atmos system. I have been doing research on dispersion of dedicated center speakers for home theater vs a book shelf or tower speaker to replace the center speaker. This supposedly helps with dispersion for all seats in the theater.
I am currently doing some upgrades of the front and Surround speakers of the room. I will have 2 left over bookshelf speakers. I was going to use one bookshelf as the center and it will match the new incoming full range tower speakers. Should I just use the one bookshelf in the middle or run a left center and right center speaker set up? Part of the upgrade is a Trinnov Altitude 16 Processor. I think it should be said if I am running a Trinnov seperate Amps are given. So basically a 8.4.4
