If you want lame advice DON'T do this!

First of all, most manufacturers don't know how to set-up speakers in a room to optimize the sound.  When my dealer friend gets in a new pair of speakers, the manufacturer always comes in and changes the positions and not for the better.

While the room is one component of the total sound, most people have equipment that they have no idea what makes them sound the way they do.  Two examples, how many have ever heard field coil speakers or a Direct Heated Triode tube component.

Audio Physics has had speaker placement set-up instructions on their website since forever.  One of our listening rooms has brick walls and I bet that we achieve better sound than most do and the room is barely treated if at all.

Happy Listening.

I've had a recording engineer who also makes speakers (I owned one of his TL-D1s) and CDs over to my place several times over the years. First thing he did was walk around, clapping his hands and checking out the corners. I asked him if I needed room treatments and he said "No, your room is fine. There's no echo." 

He even pointed up to the popcorn ceiling and smiled. I guess it's better than a smooth flat surface. It's a small room, relatively speaking, but I do sit 9' back from the speakers with the rear wall behind my head. 

Before anyone complains about reflections, remember that if the distance from your head to the rear wall is less than the circumference of your head, your ear-brain mechanism will filter out reflections. Ask any spelunker how they locate someone lost in caves. They put their back up against the rocks and listen. Besides, it takes delays of over 40ms to be perceived as an echo and that's not just gonna happen in my room.

I've also had a high end and well respected audio dealer over a few times and he enjoys my listening space. I use no room treatments at all. Sometimes with a near field listening set up you can get really good sound with not much fuss.

Recording studios are there for getting the most out of a recording and once done, there's no great need, if any, to replicate that same environment. The work is done. Sit back and enjoy the sound.

A room can sound bad...

Then it must be corrected acoustically...

A living room room can sound good with no apparent defect...

Then you can live with it without doing any acoustic treatment ...It will be just ok... It will not be optimal...

A DEDICATED room can sound also OPTIMAL for a specific system and could be more than just OK...

Then even if acoustic control is not necessary because clapping your hand there is no echo , doing it will be rewarding more than any upgrade...

Small room acoustic is way more than just suppressing the echo in the room... 😊

Do not confuse these three different cases...

The gear does not replace acoustic optimization...

I understand that most people cannot do it and cannot pay someone for doing it ...

But we must say the basic truth... Acoustic is not a mere correction ....It is a process of optimization of the relation between your ears, the room and the speakers...

If i could had better speakers than my Mission Cyrus , my room optimization would have crush even my actual stunning headphone in intimacy and in all acoustic factors...

I'm not confusing the three cases you mentioned. I was told by professionals who've sat and listened to music for hours at my place that nothing needs to be done to improve the sound in my room.  

I understand the points you're making. I guess I'm just lucky or it could be that minimal room treatments are all anyone really needs, unless they want to make a shrine to the audio gods. 😄

This is my second case...

you room was good then you were lucky...

But room optimization , my third case ,only  begin with a good room and do not end there..

Almost no one had listen to a dedicated small room , because almost no one own one...

And pro dont want to "create a ashrine to the audio Gods"...A good room is enough for most customers ...doing more will cost a fortune...

Thanks for the expression... Room optimization is a "shrine to the audio Gods"...

Ask to people who could pay 100,000 bucks for their room if their optimized room is better than just a good room or not ? They will say that there is no comparison...

Then i did not negate your point nor want to depreciate your room ... I only add what was missing for the sake of understanding and from my experience...

By the way it was so hard to create one optimized room i will never do it again... And i lack the 100,000 bucks to pay for one...

😊

My unesthetical room with 100 resonators and other devices was that : "a shrine to the audio God" ...

Good expression... It is better than "mad scientist lair"...
