My pleasure, my friend.

The 6cm would be fine also. This is the page I am looking at.

The mic will pick up more what's coming from the "primary" wall, so ideally you want that covered as much as you can, specially since you're planing on adding more stuff on the room later. It's just moving one panel from the right wall to the primary wall to priorize the primary wall, nothing more.

Membranes. Anything that involves the vibration of something really.

That's an improvement. Doesn't look very promissing though, acoustic foam is not that effective unless it's properly made (and ideally measured) and i doubt this one is.

At corners?? Never heard of such approach.. I would heard that recording studios use corner membranes or something..

 

It's almost impossible to tell which bass trap is best as these companies aren't really showing verified coificient information or what they are actually made of. For instance this might be good at a great price where you could do multiple corners, but who knows if they are made of the right stuff.

Yes. Anywhere you have pressure build-ups.

Because they are also sold as bass traps. You would need to see the specifications to see that there's some kind of membrane or resonant element inside. It's not the only way to make a bass trap work but you see it pretty frequently.

 

What are bass traps?

Standalone? Weird.. Won't the sound "slip" around it and return to room giving weird impression or will it be decreased by absorbers?

 

No, bass frequencies are to large to slip around tiny corners. You're dealing with the nodes that cause problems. You'd need HUGE bass suck to actually absorb 50 foot low low end.

 

Okay so you gave me a standalone, portable approach that I adore, but what do you think about these quartered ones?

Rooms with smooth walls and high ceilings often suffer from disruptive reverberation. To reduce this, acoustic foam elements can be used. Pyramid or convoluted foams are ideal for absorbing unwanted frequencies and improving room acoustics. Installing bass absorbers for low frequencies and broadband absorbers can further optimize the acoustics. It is recommended to cover approximately 20-30% of the wall and ceiling surfaces with sound absorbers. Materials with a thickness of at least 60 millimeters are particularly advantageous.

 

It seems hard to tell without documentation of the product. A 5 cm plate might not be as efficient as another company's 3 mm of a different formulation.

Remember, I'm not an acoustical engineer and can only give advice to what my uneducated, life experience can muster.

 

@canbi
Listen what @arsch said.

If you don't believe it:
Put a thick blanket over your head and sing. It will sound better, than anything you put on walls in such a tiny room.

Still don't believe it?
Buy a measurement mic and measure your cave with REW.

Then go here and calculate the needed thickness of absorbers you need to have even a small impact on the 100 Hz range:
http://www.acousticmodelling.com/porous.php

You need to understand the basics, otherwise you don't know what you are doing:
room modes are reflections of airwaves
airwaves are moving molecules
damping the movement of a molecule in airwaves needs resistance
the resistance is dependent on the thickness of the resistor (damping material) and how dense the material o the resitor is, to de-acceleate the molecules in the airwave

Do not work against physics work with it:

1. Accept the physical reality ->
2. Give headphone monitoring a fair try (you will need headphones anyway) (as I said: pay UTMOST attention how comfortable the HP feels after 1 hour during summer; you don't have anything from the "best HP int he world" if your head hurts or your ears melt away)
3. If HP monitoring really is not yours (try different HPs and software) then
4. go for the most bass shy speakers - which btw are also the best ones for mixing and (even producing, but without fun) anyway: Auratones.
5. If you go the Auratone route, you still will need lots of acoustic treatment.

 

It's not about mixing, it's about recording vocals.
