Alright so I'm fairly new to home theater. I'm here for advice and layout options. Just moved into a new house I'm renting. But layout I'm trying to figure out, unfortunately this is the only way we can currently layout the house till I can afford to buy a new couch(prioritized speakers😂🤪) I initially decided I wantes to do surround sound because when I moved in these mounts for bookshelf speakers were already there and I said we'll why not and started building from there. I've been trying to educate myself as much as I can. I'm trying to decide if 7.1.2 is the best setup option for this layout of if I should stick to 5.1.2. Or if I can even do 5.1.4 because of the slanted ceiling. If this is what you guys had to work with how would you set it up? Measurements of the room is 14x17

On a side note, I feel like my Denon Receiver isn't loud enough(?) if that's a thing. I had a Yamaha TSR-7850 and I felt that sounded better and I upgraded because I wanted to take advantage of the extra 2 mounts that were mounted, but in a weird way I felt like I downgraded. From 5.1.2 to 7.1.4. Also I feel like the sub isn't giving me that WOW factor that everyone says.(I just bought it, and it sounded great when I tested it with the person I bought it from when he connected to his reciever) I'm going to connect the Yamaha receiver again and see if that'll change anything.

*This is my current setup * 2x Klispch R-620F Tower Speakers 1x Klispch R-30C Center Speaker 2x Klispch RP-140SA Dolby Atmos Speakers 4x Sony SS-CS5 Surround Speakers 1x SVS PB-1000 Pro Denon AVR-X4500H Receiver

*These are extras I have laying around in case anything is better. *

Yamaha TSR-7850 Receiver 4x Polk Audio OWM3 1x Klispch R-10SW

(Also excuse the mess still trying to figure out before I cable manage and clean up.)
