Speaker Placement a Key to Imaging

[toddalin]

I would like to have some "3D cork" placed along the angled ceiling. I know that hanging panels would probably work better, but would appear more obtrusive and could interfere with the surround speakers.

I know that this gets very expensive, very quickly and when I corked a wall back in 1981, it smelled up the room for a dog's age.

Also, while it would certainly deaden the reflection, I have no idea what it would do to the imaging.

Hi Todd,

Depending on your approach it needn’t be expensive.

I looked at acoustic treatments sold by the pro audio industry and HIFi retail and was immediately put off. So l looked at local manufacturers of residential and architectural acoustic treatments. I then found an acoustic consultant to help me specify the room.

A key point is not to second guess what you think your room needs. It’s a very deep rabbit hole that is best left to an expert. If you get it wrong it’s a big problem. Don’t be sold up the river by a retail salesman who really has no idea other than recycling his grandmother on eBay. You may not need diffusion. If you do you can make your own or buy it from a wholesaler.

I need my room to cover several different needs including a living room, a stereo listening space, Atmos HT and Tele conferencing. It also need to look great.

The fee for my acoustic report was under $1,000. That was an independent report not associated with any finished products. Full specifications and build plans were provided. This way l was able to incorporate the treatment during the renovation. A furnished room may have enough diffusion.

The rack and the console are for illustration only. But l intend to make them when time permits.The rug is real and yes it was expensive but l wanted a large 3.8 x 5 m wool blend rug. I had the curtains made by a local company. The decor is based on a Palm Springs / Coastal theme.

The ceiling is ~465 sq ft. Even something this simple would run ~$1,250 just in materials, not including the labor to install. And we would probably want something nicer (=>$$$).

I have never been terribly impressed with the performance of acoustic tiles.

Perhaps you could consider something like this?

Ian, who is selling this?

Ian, who is selling this?

It’s a local company here in Australia

There are plans on www

Maybe Rob can start a new thread on room acoustics.

Ian, who is selling this?

Yes, much interest for this.

Also, no more pics of 'Vettes! I'm bummed. Got moved to "Off Topic Forum", no doubt where dreams go to die as one has to apply for access. (which I did, but haven't got yet..) Makes me wonder how many other members do not have access and thus do not see threads from within.

I had thought of that sort of thing but feel that it may interfere with the front and rear surround channels and/or block the projector to be truly effective.

That maybe the case.

I’ve got six Dolby Atmos top loudspeakers and no issues. Room treatment is only ever used to solve a problem. My ceiling treatment is only in one location.

My main treatment is at the front and rear and the front sides. My panels are proper acoustic absorbers from 250.+ hertz. Not foam tiles. l have five bass traps for below 250 hertz.

Before this l had slap echo and the room ringed out. I opened up a stud wall and introduced some room treatments. It now sounds great.l would k also had some first reflections due to my room being a bit narrow (4m)

It depends if you think you need to introduce room treatment or not.

If you don’t then leave it well alone. Too many people think it’s a magic bullet like a lot of things in the HiFi scene. In some situations the shape or size of the room will dictate your options. In general small rooms are more difficult to work with than larger rooms.


Cheers

Hi Todd,

I only have a 2.4 x 1.2 m panel on the ceiling.
As l said try not second guess your requirements. Every room is different.

But generally it’s the first reflection points that are considered on the ceiling (not the entire ceiling) that is of interest. This is sometimes referred to as a cloud.

I think my panels were about AUD$300 each.

If you are interested a report can be done remotely. I used REW and provided a detailed set of sketches with room dimensions and photos. REW is a free ware download with comprehensive help guides. It has an RTA btw. I downloaded the latest version yesterday and it’s loaded with tools for evaluation of room acoustics. Mics are available with calibration files at a reasonable price.
