New home cinema prewiring and setup - do I need a professional?

Recommended Posts

Yep I think 3.25m room definitely 16:9 screen.

 

Mine is 3.3m wide and I think a 120" 16:9 just fits. I went with 110" 16:9 though.

That’s heaps for the advice. I see what you mean and I moved the rear ceiling atmos forward. The seating position is about where the orange conduit is. The side surrounds are on wall so I can move them forward or back if needed. What do you think of the positioning of this now?

You need to move the atmos speakers further away from the side walls, they are way too close still - in this photo.
I used the Dolby template and it's not good. And although I had good off axis speakers in the Kef Ci200rr-thx the Atmos effect was not that big of an impact. I ended up rigging some speakers to a temp pine structure over the mlp and found it sounded way better with them further inside there original fitted positions. Only thing is the new positions are loaded with cross beams and other stuff. So I will make my own on ceiling in room speakers.
Have a look at the photos below. You can see I have started to patch up the holes lol.
I also marked where I will have the new speakers placed.

Cheers, I’ll check out the locations of speakers this weekend as I’m doing all the wiring before plaster goes in next Wednesday. I moved the projector power and Ethernet point so the projector will be at 4.50m from the screen.

I can move the atmos heights 1 space inward towards each other, because surrounds at the back can be moved will this make issues with the atmos heights not in line?

id move them in one slot.

 

we havent seen a layout as yet showing speaker location in relation to the room and seating so makes very hard to comment as looking at photos you can be thrown off by perspective.

 

looking at that last shot for instance the side still look too far back in the room and front heights too far forward in comparison. 

 

but again that could just be perspective playing tricks in a photo ... who is to know...

I’ll measure up and post the specs. Ives moved the atmos heights closer as you can see in this one
The rear atmos heights are 1.5m from rear wall

Just reading through your dialogue,  lots of good advice. I'm just about to start my pre wire plan too so it's all good advice for me too. I'll be going atmos too however I have a 5.6 x 4.5 (approximately) room to play with. Im planning on running my amp at the back of the room to keep the front as clean as possible.  I'll use 1/3 rule too but im not going to be too stringent on it as you can't cater for every seating position. We'd all like to be front and center but it's just not practical. 

 

Looks great so far. 

 

Regards.

Sounds good. I’m doing last checks on wiring today. Bit annoyed as the builder has not put the right acoustic insulation in. They will need to pull it all out and do it again in the theatre room.
