I posted back in May of 2020 about upgrading my setup and everyone was so helpful! Seems like forever ago and just yesterday at the same time.. thanks COVID. :)\n\nLong story long we ended up planning a large build \/ reno (gutted and redid everything) of our house that started April of last year... currently at the insulation phase & I'm starting to plan my equipment upgrades \/ purchases for the new dedicated theatre room. Unfortunately it's in the pre existing part of the house & only has 8ft ceilings. Room is on the smaller side for a theatre at 15'2" x 18'10" with the theatre coach located on the long wall. I'm doing some pre wiring now with 300 feet of way more expensive then I expected audioquest low db cable. Here's my plan \/ quesitons... \n\nI have a Denon x6500H AVR - Everything else I posted about 2 years ago will be replaced... Running with a Samsung LSP9 UST for a 130" projection on the other long wall. \n\nI'm planning to go all in on Paradigm because I've read lots of great reviews, they're Canadian, and they seemed to be recommended a lot in other posts across the forum (mine from years ago included). \n\nInterested in doing 7.2.4 with 4 in-ceiling atmos. I know in other posts people have recommended dropping 2 of the atmos ceiling speakers because of room size and angle with a coach close to the wall... but also others have ignored the specs & went with 4 anyways and seem to enjoy their system (for whatever that's worth). \n\nCenter: 600c\nL&R: 800f's\nL&R Back & L&R Surround: I'm a little spun around on what works best for these channels. 200b bookshelf? Surround 3 high-performance? Other Paradigm recommendations?\nCeiling: CI Pro P65-R or H65-SM CI? For Atmos will there be an audible roi going from the home to pro?\nSubs: Two Defiance likely x15's or x12's. still deciding on size and placement as it gets a little wonky spacing out the screen wall with so much real estate taken up by the screen itself. \n\nLinks below for all the product mentioned. Pics attached of the rough room in progress. We added insulation bats to ceiling and interior walls to help with sound deadening. \n\nWoofers\nCenter\nL&R Front\nCeilingA and CeilingB\nBack and Surround options.\n\nThanks in advance!
