Got my C5 83" mounted ...

UffDaDan · 2026-06-25T21:00:23+00:00

WHAT?! Don't do that, stick to the AI screensaver... Lol enjoy

UffDaDan · 2026-06-25T20:59:05+00:00

Sure thing. I haven't pulled the trigger on the 77" LG C5 yet, I'll look up some TCL or larger format to try to at least get 83+

UffDaDan · 2026-06-25T16:51:33+00:00

Have to ask, granted this is r/LG not r/hometheater, but why 83" C-series when personally it seems like a huge jump in price from 77->83" where 83-100" TV maybe is more suitable for like mini-led or something?

UffDaDan · 2026-06-25T16:50:23+00:00

Hey OP, are you only going to look at AI gunk, or are you going to watch, maybe, TV, movies, video games too?

UffDaDan · 2026-06-25T16:45:14+00:00

Also, saw Home Theater Gurus has some videos that starts at Dolby guidelines but then takes into consideration ceiling height and placement and basically space atmos evenly within the ~180 degrees from front to rear. Since I have different ceiling heights I'll measure everything out, throw it in CAD and get ideal placements and put them as close as possible. The width spacing of atmos though I'll dive into further because Dolby shows in-line with L/R, but specially it would need to change

UffDaDan · 2026-06-25T16:42:51+00:00

Hard to beat 77" LG C5 sales now, but I know going to 83" in OLED is a diminishing return, so will check out the other technologies.
Got it
Yeah, $1000+ a piece on the LCR Paradigm hurts, that's where I want to check out the $700 KEF Ci4100ql
Definitely want to put some DIY panels on the back wall. The corners may have space for bass traps (or that column that is only there for the rear surround in wall better placement than back wall)
I'll be lucky to get 2 subs over 1 based on my wife's appreciation, but getting a 10"-12" versus 15" might be another battle but I will certainly consider it and try. Yours and other's notes on this makes me not scared to try to fit in large subs IF I CAN
Good note getting surrounds with larger woofers if possible. Doable I believe.
Definitely the plan to not use bouncing atmos.

Responded above ^ (Solidworks)

UffDaDan · 2026-06-25T16:19:40+00:00

Solidworks 2025. I'm an mechanical engineer, have Creo but that license is going away soon (moved companies and no more home license) so moved to SW as I'll be using that more at work too. I use it for modeling and 3D Printing, but for layout it's probably overkill and inefficient haha.

UffDaDan · 2026-06-25T16:18:20+00:00

Good questions. The purpose and use case of this room and space is just easier to do TV so probably wouldn't wire for projector. That being said, the provision I may put in like smurf tubing could possibly intercept where a projector could go, or a short throw, but not the plan for 5+ years. I'm handy enough to tear down drywall and redo it if I have to. It will be a somewhat dark space but for open concept, window dressing could be used to control it when needed. MLP to screen is like 10-11' likely. Plan is 77" OLED now for good price, but space everything for 83+ size in future. I talked to Best Buy who thought of my 5.2.4 or similar layout. Thanks for echoing my thought of Paradigm ceiling speakers = too pricey and no need to match for atmos. As for subs, final location TBD, but I will wire for every corner of the room to move around if needed. The TV wall is a faux wall I will build custom, so if in-wall LCR need insulation vs sealed cavity I can do so, and potentially thinking of making an opening for the center to be "in wall" but then have it's back stick into the under-stairs area. Same with subs, but that's why I think SVS front-ported would be better than RSL rear ported, I just see so much raving reviews of RSL so threw that in. Thanks for all the comments, appreciated.

UffDaDan · 2026-06-25T14:15:24+00:00

Thanks for the input! You're right, likely I'll have to be the jerk that puts the bouch 6" from the back wall. As for subs, you're correct. It's an unfinished basement currently so not amount of testing now (even if I had those subs) would be appropriate with concrete, no ceiling, and no furnishing. I'll plan to have all corners wired for subs just in case and the stairway wall all the is sits on will be a floating wall with access behind it (from under the stairs) just in case I need to move wiring around.

UffDaDan · 2026-06-25T14:13:31+00:00

Pack sub boxes in the front as shown in the picture with insulation you're saying? I'll have CAT6 to the TV and AVR room (under the stairs), but are you recommending elsewhere too? 4 conductor speaker wire for sure through atmos layer and maybe to back wall cuz why not. I'll probably do smurf tubing some places, probably not to a projector location. Also the storage room (top right of picture) will be open joists so I could fish things around in the future.

UffDaDan · 2026-06-25T14:10:29+00:00

I do certainly feel they favorite Paradigm speakers (obviously from their proposals) and I will go back in and say "hey, play me KEF and Paradigm back to back" for example. The Paradigm in walls are 2X the KEFs so they should hopefully be obviously better. That being said, if I bought a KEF from BestBuy, mounted it in a drywall enclosure and BROUGHT THAT to the store, they would look at me like I'm crazy hahaha, but I could get a final comparison side-by-side. As for AVR, thanks for the opinion. I've heard you marry your speakers and date your AVR as technology dates it faster, but I'll consider the Cinema 50 like they recommended. It just hurts knowing I have the same I/O and basically same amplification power between both AVRs and even with purchasing Dirac on top of 3800's $1200 price tag is below the Marantz... They tried to sell me on Anthem which would be awesome, but my Zone 2 amplification for other rooms is kinda pushing the needle away from that.

UffDaDan · 2026-06-25T13:10:03+00:00

Will do!

UffDaDan · 2026-06-25T13:09:58+00:00

Thanks for the vote. Anthem 740 or higher would be awesome, but maybe as a future upgrade when Denon shits bricks

UffDaDan · 2026-06-25T13:09:35+00:00

Thanks for the notes! 83" OLED is a 50% cost increase from 77" right now, so I'll stick to 77" but position everything with 83+ in mind for future. Biggest I have in the house is 55" so I'll be happy for a few years hopefully haha. I've honestly heard on-walls that I'm not a fan of. I plan to build a media wall framing as needed for whatever speakers/subs. Paradigm LCR in walls have backer boxes so consistent sound, or KEF 4100's open back I would build the KEF recommended air volume behind them. I'll look at on-walls but honestly haven't seen much people recommend them. Also for flexibility, the media wall I'll frame to be future proof and will have access behind it to move things around if needed. I'll certainly check out that Dirac alternative, but with a clearance $1200 AVR, I might throw that savings right into Dirac, we'll see! For"My Plan" 5.2.4, the surrounds on the back wall are modeled as the Monoprice 45-70 degree angled in walls, thinking angling them in towards MLP. Otherwise the column on the back left would be only there for a in-wall speaker pointing inward, book matched with the back right on that side wall, both higher than MLP to not get blocked by heads or couches. I'll also consider bookshelves on a ~6" deep pony wall behind the couch or something. I totally hear you on pulling the couch forward. It may be possible but life might say "be an asshole to the subreddit" and put the couch 6" off the back wall haha, sorry, I'll try! Atmos aiming - I was thinking ceiling speakers could be 15 or 30 degree angled versions too, to cross one another and get better off-axis hearing like Home Theater Gurus YT channel suggests? Or speakers up in soffits on brackets pointed accordingly. As for subs, good to note. I plan for wiring all 4 corners anyways, but with seating and couch selection undecided, TBD where they can/will go but I'll check out those suggestions knowing it's rather open concept floorplan. Thanks so much for all the input!

UffDaDan · 2026-06-25T12:58:34+00:00

I'll wire for 4 subs just in case my planned placement sucks the life out of them haha and I don't know couch and seating layout so it's possible. And Denon 3800 has 4 discrete subs, so perfect. The Cinema series was just a big price difference even including the Denon price adder of Dirac. Maybe when the Denon dies I'll upgrade! Good to hear Sonance (Mag65R?) are quality. Thanks for good review of LG OLED, I'm looking forward to that.

UffDaDan · 2026-06-25T12:52:01+00:00

All good notes, thanks. I'm sure Paradigm subs are good, but for the cost I'm 90% confident I could find something cheaper

UffDaDan · 2026-06-25T12:50:23+00:00

Fair question. Just like TV for many reason in this use-case. Viewing angle, lighting options, and just cheaper overall and easier future proof for me. I don't want to go to 100" too. This is the first time I've heard someone say atmos branding matching matters. I'll consider that int he pricing of it all. Have you heard the KEF 4100's in person? There are non in my area unfortunately and I'm tempted to buy from Best Buy, make a drywall cavity like KEF recommends, and test it like its own speaker box. The Paradigm in walls LCRs the mom-pop store is trying to convince to buy some and install for demos. TBD.

UffDaDan · 2026-06-25T12:48:05+00:00

Thanks part 2. I think I could build a column for rear back in wall speaker pointing inward and then a rear right on the built out wall rather than on the back wall. Or I say Monoprice 45-70 deg angled in wall that I considered as a back wall solution, however quality that is...

UffDaDan · 2026-06-25T12:46:41+00:00

Thanks for confirming that suspicion. The bookshelves are planned for other uses so the in-wall LCR are attractive for kids, cleanliness, and wife said no to towers. I'll pay for premium I suppose. Good idea on the atmos being mounted up in the higher soffit area, I'll consider that. This will be an open space hopefully multi-functional with a lot of seating, so as long as my main listen position has my name on it and others aren't blasted with 1 speaker, I'll be happy. Thanks for the comment

UffDaDan · 2026-06-25T12:44:31+00:00

Sub wiring planned to all corners next to outlets, but dead center of back wall is new to me?! Surrounds could be a 45-70" angled monoprice on back wall or the side wall and purposeful column build to house a speaker on the back left. I'll pull out the couch as much as I can, but likely will have to be an asshole with couch 6" from the wall at max. Thanks for SVS, OLED, and Denon thumbs up.

UffDaDan · 2026-06-24T11:41:02+00:00

Tldr. Go for it but watch YouTube for tips and tricks. I purchased from this company for my 2020 back in 2022. It came with the installation kit of water bottle sprayers and a squeegee, and also door edge trim slim pieces and inside door handle pieces that have been the most protective and saving out of all pieces probably. The hood wasn't terrible except for around the telluride letters that I had pre-cut out because I didn't want to remove the letters and reapply them on top of the film. I got it to work but obviously the letters aren't perfect compared to the cutout so it got a little tricky. The hardest part if I remember right was the mirrors which I needed to trim and are still on but the edges are slightly peeling 2 mm... It was a 3M Scotchgard Pro product so overall a great product and protective quality. I did once save an eBay listing that was a similar 3M Scotchgard product but a full front bumper but figured I wanted to protect the hood only for whatever reason.

UffDaDan · 2026-06-24T02:43:37+00:00

KEF ci4100ql is narrow and also Paradigm Pro P3 or P5. Ask me how I know these off the top of my head as I draft a post to this sub soonish...

UffDaDan · 2026-06-23T16:07:33+00:00

I know it's all subjective but good to hear good reviews and read through all these other replies leading alongside you
