I've been into home cinema and hifi/AV for about 20 years, and I've always dreamt of having my own dedicated setup with a big screen, and not a system that is shoehorned into a bedroom or a lounge. I also wanted proper overhead Atmos!

Finally the time has come. We've bought a house, and I was given permission to go nuts in the spare bedroom, on the proviso that it can still actually be used as a spare bedroom on the rare occasion that we have guests. One sofa bed later, that problem is solved. It isn't the most aesthetically pleasing, but it was free! And it is comfortable.

This thread will serve as a mini build log with 'finished' photos, and I'll update it when I make changes to the room as time goes on.

All of my equipment is carried over from the setup in our old rented house (as seen here: Yet Another Lounge-based Home Cinema: MyImmediateNeighboursProbablyHateMe edition.) - a collection that I have built up over a few years - so I just needed to buy a projector, a screen, Atmos ceiling speakers, and the usual cables/accessories.

It's a small room (the usable space is 10.2' x 11.1') and so I had to be smart with the positioning of the furniture, but the layout is ideal.

I chose this projector as I wanted the proper lens shift adjustment, and not to have to rely on keystone. By luck, the ceiling joist that it is mounted to is almost central, but not quite. I was also on somewhat of a budget, therefore a decent 4K unit with the optical adjustments was considerably out of my price range.

The screen is really excellent quality and was a delight to put together. The material is highly tensioned onto tabs at the 4 edges, so there's no creases or ripples. The wall isn't quite flat, meaning the screen isn't quite flat, so there are some very minor focusing issues toward the edges but this is only really noticeable when you're reading smaller text from a computer input, for example.

My latest job was to get the frequency response of my sub flattened with my MiniDSP. Turns out, the room response is quite amazing without any EQ, so a little bit of a reduction at 52Hz was all that was needed. See the graphs below.

The next step will be some acoustic wall panels for sound deadening. While the sofa, carpet, and thick curtains certainly help, it's still quite a "live" room, especially with the speakers shoved right into the corners.

Hi, very nice. well done. you can go bigger with the screen, maybe!

I decided to wall-mount the speakers which has helped a lot with the sound field, by raising them slightly above the listening position and allowing them to be positioned more accurately.

Also put up a couple of film posters, as is customary in a proper home cinema ;)

Great work Howard. The dream of a spare room to convert lives on with me :D

Today's tweak was to reinstate the "paving slab under the sub" scenario that I had in my old house, which really helped decouple the sub from the floor. This resulted in considerably less vibration through the floor which means (slightly) happier neighbours, and cleaner bass.

The frequency response is unchanged, as per the before-and-after graph below, but there is vastly less floor shake which should mean my immediate neighbour hears less LFE!

I wounder if a dedicated acoustic platform such as an Auralex SubDude would improve things even further?

I'm yet to look at this yet for my subwoofer. I did have a pair of MoPads way back when i had my SPL800R, however, as it stands, my current sub is on bare wooden floor.

Maybe once i pick up a MiniDSP and UMIK-1 i'll look in it and compare results. Anything for a tweak!!

I doubt it. The general idea is to decouple the sub from the building, if you have wooden suspended floors, by sitting it atop a very dense mass.

The SubDude HT (the one big enough for my sub) might look slightly more "polished" but it's almost £100!

Room treatment. If you haven't done it, do it now.

Seriously.

It's the best-sounding upgrade you'll ever buy.

This was the next chapter in my home cinema improvement path, having promised myself I'd look into it when I got myself a dedicated room.

In short... Wow. I've always known room treatment has a huge positive effect but I wasn't expecting quite such a profound improvement in my little room.

Slap echo has been massively reduced, and it all sounds quite "dead" when talking. Stereo imaging for music is vastly improved with greater detail as a result of less reflection, and voices from the centre speaker are so much more clearer and pinpointed to the actual centre that it sounds like I've upgraded the speaker! However, the surround sound soundstage still sounds vaster than the room dimensions would indicate.

Very happy.

Looks very good and almost identical size to what I have........in the process of completing.

Where did you get the sound panels from?

I borrowed a friend's wide-angle lens for my DSLR and thought I'd take some nicer, "glossier" photos which show the space better:

Looks very good. The only thing I'd do in your shoes is take off the dado rail thing as I think it spoils the room, and as it's a cinema room maybe even paint the walls a tad darker.

All nit picking though as it does look great as is.

Looks very good, congrats !
One question, doesn't bother you the projector noise ? I was also drawn to the idea of a projector, went to a showroom to see a Sony VPL-VW270ES (great image IMHO!) but the noise that the projector made was just to loud for me. Especially that it should stay just above sofa, like yours.
Your projector is rated at Normal: 32 dB (A) - Economy: 24 dB (A) noise level, Sony declared value is 26 dB for normal use (Low lamp mode, for High mode it would be even higher).

I use mine in Eco mode and whilst you can tell it's there, it's very quiet and in no way intrusive.

I originally had white ambiance Philips Hue GU10s in the ceiling, since I told myself at the beginning that I didn't need coloured bulbs up there.

It turns out I was wrong, I did need them, and I couldn't resist picking up two pairs of the new richer colours GU10s to add some sutbly-stylised light as the cherry on top of the room, so to speak.

I feel it adds a really nice extra ambiance and gives it a more 'premium' cinematic feel. The photos are deliberately dark, showing my favourite scenes that I use for pre and post-movie watching, as well as the dark red which I usually use while watching.

The two floor-level light strips serve as walkway lighting.

They all wash it out to the same extent really. I tend to have them at their minimum brightness when I'm watching something anyway, in which case it doesn't tend to affect the image.
