Home Cinema Project Mark 2

Hi guys,

I last posted showing my home cinema project a few years back, which when finished i was very happy with.

We have now moved house and part of the negotiation of sale of my old house was the cinem room - seems like my buyer liked it too!!

So now i have to do it all again, and thought i would post the progress as i found the forum really helpful looking at other peoples successes and failures.

In the new place i have an old stable block which the old owners converted to an office. This room is 8.25m x 5.45m, and with a kitchen off this room seemed the perfect place to start!

I was very happy with the way the last project went so decided to go along the same route but upgrade the kit a bit.

Attached are pictures of what the old owners used the room for to give you an idea of the space, some pictures of early stages of raising the floor (not very interesting ones!) and my drawn out floor plan. I have now finished raising the floor which i did to hide the speaker cables, electrics and to put some insulation boards between the batons and this weekend finished construction of the stud wall for the front wall to hide the left/right/centre speakers, subs and to hang an acoustically transparent 9ft screen on it. I will post pictures of these later tonight.

I have also built 2 bass traps behind the screens, these are very rudimental things and i will see how they make a difference to the sound. I have started talking to GIKAcoustics (very helpful and great website for research) who suggested 12 bass soffits but at £ 500 each i thought i would go with the diy route first, and you wont see them as they are behind the screen. I will go with six 242 acoustic panels to help the reflection points though and 3 Monster Bass traps for the rear walls.

Kit list - all bought from Richer Sounds City who were excellent (as usual).
Sony VPL VW 320 4K Projector (upgraded from a Panasonic AE 6000, which i was very happy with).
Pioneer SCLX 901 to take advantage of atmos (upgraded from a pioneer SCLX 56)
Dali Opticon 8 (all old speakers were Dali Zensor which sounded amazing)
Dali Opticon Vokal
Dali E14 Sub (2 of these bad boys!)
Dali Opticon 2 (4 of these as running 7.2.4 system)
Dali Phantom E80 ceiling speakers (4 of these)
Panasonic DMPUB900 (was going for an Oppo but wanted to take advantage of the networking capabilities of the Pannie as want the option to use it for Netflix)
Sapphire 9ft Acoustically Transparent Sreen.
20 linear metres of acoustic fabric to wrap the stud wall in.
Q Acoustics Media 4 - This is going under the TV i am putting up over the AV rack in the corner of the room. The reason for the second TV is for XBOX. in the last house i couldn't play XBox Kinect with the kids as every time i stood up my shadow was projected onto the screen as the projector was behind me!!
Sky Q SIlver - Sky are coming today to move the dish and sky q box from the house to the annex. - How annoying is it that they wont let you have a 2nd sky q box, but thought we will use the sky mini's in the house as they do not output 4K and i would prefer the sky q silver box to output 4K to the cinema.

All the AV equipment is going in the back of the room, as didn't want any annoying lights distracting from the picture! My one concern is the length of the RCA cable i have run for the subs as i have read about interference. The cables are 10m and 15m lengths, do you think i will have any issues with these? There is no electric cables anywhere near them.

Some pictures showing the early stages. Floor now finished, raised up by 50mm with insulation and wires all hidden now. Stud wall built, waiting for the speakers to arrive on Thursday so they can go behind the wall then wrap the wall in acoustic fabric. It will be a busy weekend as all the equip arrives on Thursday so i can start fitting the ceiling speakers. Hopefully even get the wife fired up to start the painting during the week!!

Any thoughts on my question in the first post about long sub cables and possible interference?

Also would you suggest the Front L and R speakers (and centre) be placed on carpet (on the spikes) rather than leave them on the chipboard to minimise echo?

Wow. Now that's some canvas to work with! What will you do about the skylights and light getting in?

In negotiations with the boss!! As it is an old stable block the roof is corregated sheets, so the skylights are just clear panels. I want to fill these areas with rock wool and cover with fabric but that idea is currently hitting a dead end as there will probably be a pool table at the back of the room so she doesn't want it to be pitch black....Think we will agree on thick blinds to cover the areas, which will probably stay closed anyway!

Little more update. Walls and ceiling painted (Urban Obsession). All wires boxed in at the back, projector up (bloody big!), All the right hand side of the front screen finished - diy bass trap in the corner now covered in fabric, Right Opticon 8 wired in, right sub in place (a lot bigger and heavier than it looks in the picture!). and finished the right hand front wall (just needs an edging bead to put along the edges). Rest of the front screen to be finished, then skirting board to be done and carpet. The GIK Acoustic panels also arrived today [emoji41]

Question - will I notice any drop in quality by having a join in the 2 rear surround speakers? The important word is "notice"!! It is playing on my mind and thinking of lifting the floor back up (as it is only a smallish section of floor that needs to come up) and laying new longer wire. The reason for the join was to have a connector plate on the floor so I could disconnect and move the speakers easily (as there will also be a pool table at the back of the room).

Very unlikely that you could notice a difference joining a couple of bits of wire together..

Pretty much done now. Still some sound treatment panels to go up at the back of the room and the ceiling though.

Sofas are old ones which will do until the cinema seats arrive!!
