    Mini 7.2.4 Home Cinema (smallest ever?)

    So I'm thinking I may have built the smallest ever "full Atmos" setup, at just 3.3*2.5m (10.8*8.2ft) :D - the room is approx 600ft³

    Here's a 3D mockup. My goal was to have a dedicated room with a layout as close as possible to Dolby guidelines, and I pretty much nailed it (to the mm :p)

    [​IMG]

    And here's the final result:

    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]

    Uncompressed images available here

    TV: LG OLED 65" B7 (1.5m [4.9ft] from eyes to screen!)
    HTPC: i5-6600K, 8GB DDR4, GTX1070, 2x 256GB SSD, GA-Z170X-Gaming7, Silverstone GD09, Noctua fans

    Speakers
    LCR: XTZ Cinema M6
    Side Surrounds: XTZ Cinema S5
    Rear Surrounds + Atmos: XTZ Cinema S2
    Subs: 2x DIY 15" 'Fi Audio SP415' sealed down-firing cubes
    Other: 2x Buttkicker LFE

    Amps
    AVR: NAD T758v3 (with Dirac Live)
    Power Amp: Arcam P-1000 (powering LCR + Atmos)
    Sub amps: 2x Citronic PLX3600 (dual 2ohm)
    Other: Buttkicker BKA1000-N

    Bass management is handled by a MiniDSP 2x4, with a chunky house curve applied to the Buttkickers - which are located in the sofa, one inside each armrest, which was serendipitous that they fit there :) - I suppose it's 7.4.4 if you include them in the sub count ;)

    I got sick of putting discs in/loading times/menus etc so I ripped all of my DVDs/Blu-Rays to my NAS, which I play back locally on the HTPC using Kodi DSPlayer (which supports madVR + LAV filters)

    The Bias Lighting is the MediaLight Quad
    Funnily enough, whilst Bias Lighting was great with my old Plasma setup, I actually perfer it off when viewing my OLED, as there's nothing quite like having the room plunge into absolute darkness. And I don't appear to suffer from eye strain without it.
    So what I've done instead is to have them automatically turn on/off when media is playing, paused, etc using a WiFi LED controller + some scripting

    Wallpaper is from here

    The paint was a custom mix, for which I got the info from here - the aim was to get a neutral grey as not to alter colour perception

    The carpet is from here - thanks @PHTheLoverman for the tip ;)

    This is only Phase 1 of my project - I plan on adding room treatment in Phase 2

    I like it, very cosy, how do you find sound separation on action scenes like gun fights or something flying over you with Atmos?

    You did very good job putting all those things to that room :)
    It looks very beautiful
    I am also curious about sound separation. ?

    Sound separation is surprisingly good, and is only made better with Dirac, which basically makes the speakers disappear (especially with the lights off).
    I hope to improve separation even further this someday with room treatment

    This setup was originally in my living room and the surround + atmos speakers were all in a very similar position relative to the MLP as they are now, so I had a good feeling it'd all work. The only thing that's different really is the TV + LCR have come forward (but still creating that equalateral triangle between MLP, Left and Right speaker)

    You are right, I think a good room treatment will greatly affect sound quality. Especially considering your 2 huge subwoofers in that room :)

    Which, surprisingly, are actually better (tighter, less ringing according to REW) in this room than my living room. Probably because the living room walls were mostly plasterboard, and these are all solid brick. But yes I'm excited to see what improvements room treatment will bring :D

    Great setup do think you’d benefit from a bigger screen with your viewing distance or is 65 sufficient, just asking because in my future set up I’d be around 2m from eyes to screen and I was think 75 or possibly going to 92 with a short throw projector.

    I think that is very well laid out & designed considering the obvious space limitations but the proof of the pudding is in the eating...........if you are happy with it and it does all the things you wanted then....its fab u lous!

    Hah, the last thing I expected is someone would suggest a larger screen :laugh:

    65" is fantastic, very immersive, 4K looks incredible and 1080p still looks great.

    Whilst 75-77" would be wonderful for 4K, and even more immersive, I fear 1080p wouldn't look as good, and SDR would look even worse than it already does (though it's still watchable, madVR does a fantastic job at upscaling, and it's very rare that I ever view SDR content nowadays)

    But I certainly couldn't justify the extra cost when jumping to that size, plus I'd probably have to slightly compromise my perfect triangle between MLP and the L+R speakers, which would annoy me :p It's also possible at that size fullscreen content may become uncomfortably big (I know, right) though cinescope content would probably be ok

    I probably could have gone with a projector in this space, but the pros of the OLED outweighed the cons of the PJ, for me at least :)

    Yeah, it sounds even better than it looks. Sometimes I think the sofa is the one eating me :p

    Thanks for the answer guess I’ll have to go demo a few setups before I decide, never thought about SDR looking bad so will have to bear that in mind

    Yeah, depends on your usage really, if you watch SDR all the time it'd certainly become more important to you, but as I hardly ever watch SDR it never really came into my thoughts :)

    Nice! I recall when this was a mere glint in your eye - hadn't realised you did it. Looks awesome. I actually think small rooms can work quite well for HT despite the (manageable) bass issues - they give a nice near field experience. Bet that room sounds great:smashin:

    Yup, with a stupid grin on my face every time I use it :D

    I got it off gumtree, it's just a basic studio rack, I believe it's this one: https://www.thomann.de/gb/millenium_sr2018.htm

    It's not perfect, I might replace it someday, but hey, it works on a basic level :)

    Is that a real photo ?

    Looks good.

    The atmos speakers cinema 2 look a lot boxer (deeper) than the XTZ sales blurb.
    Looking at some ceiling mounting, though would prefer not to insert into the ceiling, rather fix on.

    That's probably because of the wide angle lens causing a distortion, the XTZ dimensions should give you a better idea of their real size

    hi, thanks for sharing.
    do you have any more pictures of your rack. it looks very clean, no wires. how is it at the back? what about cable management?

    Here's a few more pics:

    https://i.imgur.com/pvbKBMN.jpg

    https://i.imgur.com/tCgHNRC.jpg

    Obviously doesn't look as wonderful as the front, but it's more organised than it looks, lots of velcro etc
    Bit of a mess as I haven't given it a proper tidy since messing about with it, removing the HTPC, AVR and sub amp, and putting them back - but at the moment it's very much a case of "I can't see it and it doesn't rattle so I don't care" :p

    I would not be too worried about 1080p and how it looks on a bigger screen, it all depends on the quality of the panel or (I know not in your case) projection system.
    Just bring some 1080p source on a USB stick and audition yourself and your viewing distance and wherever you can find with say, a 75" TV setup

    Yeah, it's definitely not something I'd be doing any time soon, but I could just emulate it with the 65" screen and sit a big closer :)

    Actually, now you mention it you are sitting v close so perhaps you've hit your sweet spot.
    I'm around 12' from a 136" screen and 1080P looks perfect still but under 5 feet is very close in all honesty.

    Since losing my old big dedicated room when we moved to our new terraced townhouse 3 years ago, my AV fetish has been completely frustrated.

    We have an integral single garage that was converted by the previous owner into a bootroom and kids’ playroom. I had looked at the 3m x 4.2m playroom portion as a potential new mini-cinema but couldn’t work out how to do it........until I stumbled across this thread.

    @richardsim7 you are my new hero! Wow, what a great room and a fantastic setup too.

    I’ll be aiming to do something very similar, starting over the xmas holidays. 11-channel Denon AVR; Kef T301 7-speaker base layer; possibly Kef ceiling Atmos speakers; 55” LG OLED.

    Can’t wait to get started with new-found enthusiasm.

    Nice job @richardsim7 :smashin:

    @nigel17 my Roon is the exact dimensions of your room. It is actually plenty of space. I've done a full 7.2.4 setup with twin SVS subs and a 120 inch projector. I think it works very well.

    Single Garage Atmos conversion

    @Drifter74 great looking room, I've seen it before on here - only I think my layout and @richardsim7 layout are both viewing across the short axis of the room onto a TV? I'm trying to acquire speakers to go 7.1.4 Atmos and am currently trying to decide on a single sub. I will be limited by having neighbours so looking for a single sub which punches hard rather than goes mega-deep and not too big. Looking at XTZ 12.17 (maybe Edge version) or BK P12-300SB PR or Monolith+ (forgetting about the "not too big" bit)! Not sure if these are available in S Africa.

    I’m not familiar with any of those subwoofer brands. I have twin sealed svs models. I moved from a ported Paradigm to the sealed SVS as I found the bass from the ported sub too unruly in the small space. With the svs the bass has similar depth but it is better controlled.
