Come on Lowe. Help a guy out

Happy to offer all the assistance and advice I can, but Falkirk's a bit of a mission

Wow, that's a big screen! Epic.

Have you done anything special to cater for your speakers being packed into the corners?

It's 110". PMC speakers are very tolerant of placement thankfully and out of shot there's a fair bit of natural diffusion and absorption along the main walls, so I've never suffered too much. ideally I'd like panels at the first reflection points but with it being a living room and not a dedicated space I've not been able to get away with it. The photo makes it look fairly narrow too, which isn't the case IRL.

Ha I know

Thank you. Your setup looks great.

Any opinions on paint colors?

At the moment, I am thinking of greys for side walls (length of room) and maybe a maroon red/navy for the two end walls. Ceiling = either the grey or the red., not sure.

Ideas?

Purpose of colour - less reflection which will aid in PQ from projector.

Also, trying to get our CDT department in school to make a few of these for the back wall:

Do they look okay?

The one problem (or not?) is that on the back wall of this room (opposite the screen etc) will be a piano. Will that cause any problems with the acoustic performance of the room? Its the only place we have space. It was either that or a 700-litre marine aquarium (due to be set up again). Given the light etc needed for the corals, the piano got the nod.

I've always fancied a skyline diffuser, but baulked at the price. I knew you can't just slap some wood together, didn't realise the instructions were easily available.

Either way, I can't see my wife allowing something with 25cm bits of wood jutting out in the lounge :/

Slight OT but whats this with pebbles and audio cables? Some sort of 'hack'? or windup?

Snake oil, like most of the hifi industry.

As for wall colour - there's only one colour for picture quality, and that's matt black. Anything else is a compromise, but darker the better if that's not practical (rarely is).

Piano won't hurt.

[Dashers]

Don't buy any wonder products for audio to fix problems you don't have.

If you're suffering from interference then you can buy some thicker generic electrical-cable and try some cheap ferrite (that's, iron) chokes and look to address the source interference.

Okay guys. I'm in the house now. As the room is bare, I need to improve acoustics.

Ideas welcome.

Cheap ways to improve this?

[neonplanet40]

Think I will try and make some panels and possibly two skyscrapers panels for the back. Any recommendations for fabric and size of wood in frame?

[Dashers]

Download Room EQ Wizard, it's free, and pick up a monitor from Maplin or something. You can then test your room for acoustic problems and apply relevant fixes.

Remembering at all times, acoustic treatment isn't sound-proofing.

[neonplanet40]

What material would be best for covering acoustic panels (if I make them myself out of timer frame and rock wool)?

Or are their alternatives worth considering which aren't too expensive?

Thanks

[Dashers]

Any material you can breathe through.

Hi folks, currently picking a projector screen. Have been told that electric is the way to go.

The width of my room is 2.77m so it seems 100 inches is really the biggest I can get.

Any reccommendations?

I've been looking at this:

I ordered a Denon X6300W and 4x MA CT265IDC yesterday.

Would this cable to suitable for the ceiling speakers?

[peterb]

What is the maximum RMS power of the amplifiers,

TBH this would probably be fine unless they are long runs or you are expecting to run the system at continuous high power

https://www.amazon.co.uk/gp/product/...d_i=B00KB0JVAE

Or go for the 14awg which has 2mm^2 cross sectional area good for 20 amps or so or 1200 watts into a 3ohm load
