The Smallest RFZ in the universe? very small project studio

[clash85dnb]

Hi, firstly i would like to express my unending gratitude and love for this forum. This is my first post but i have been lurking for a longggg time and the knowledge i have acquired from this site has been invaluable. So a massive THANKS

Im a electro/techno/Bla Bla DJ/Producer from Leicester, uk. I have a very very very small studio space available to me but I'm attempting to make it the best i can. This space is for critical listening/production, I'm not planning to record any instruments/vocals there, mix and produce ITB. Im currently in the planning/design stage of my build.

The "studio" (not sure the size allows me to call it that lol) is at the end of a double garage. The Garage sits on a concrete slab that sits on the Earth (no need to float anything i hope ). My main concern at this point in time is getting a decent floor plan for the acoustics inside the room, the isolation side of the build I'm not to worried about as i think i have a decent enough grasp of the subject (mainly form this site ) and have also built a room in the exact same spot this room will be before i had to demolish it with more than adequate isolation (its a long story that ended with the rooms destruction )

So the internal space i have to play with is

L 427cm
W 192
H 205

These dimensions are the internal space after the construction of the isolated "room in a room"

Yes its SMALLLLL but this is what i have

I am Planning to use johns "inside out" internal leaf construction to maximise space and have as much absorption as possible, i know I'm gonna need it lol. I'm also planning to Soffit/Flush Mount my Adam s2x monitors and would like to get as close as possible to a RFZ as i can in such a tight space.

i have been Juggling the soffit angle, 38% listening position, Equilateral Triangle "rules" etc etc for what seems like an eternity so any input from minds far superior than mine would be amazing.
I must apologise for my terrible SketchUp skills on these pics but i hope you can get the idea anyway.

Again thanks so much for this amazing forum, its a gold mine of great advice and it has helped me massively already.

Hi there Marc, and welcome to the forum!!! ::)

its a long story that ended with the rooms destruction

That sounds like a tragic and fascinating story! Hopefully you'll tell it one day... "destruction"! Oh my... Sounds violent... and sad.

Ummmm.... errr..... Okkkkkayy...

Good plan! You'll need every trick in the book to fit a studio into that bathtub!

I admire your enthusiasm!

38% listening position,

38% is not a rule: I'ts a guideline to a rough approximation of an initial starting point... It's not written in stone: You can vary from there.

Equilateral Triangle

Also not carved in stone! can be varied. In fact, the version you often see in books and all over the internet, is wrong. It only works for people who get their ears surgically transplanted onto their eyeballs...

In reality, the axes of your speakers should NOT intersect in the middle of your head: They should intersect about 30 cm behind your head, give or take a chunk.

And the 30° angle is also flexible: It's OK to go down to about 25°, or maybe even 20°, and up to 40°, or maybe even 45°.

So probably something in between your two extremes would be good. I would also try to get your speakers closer to the front wall if you can (slide the entire soffit forwards), to maximize room volume. Room volume is always important, but in your case it is critical. Squeeze every last mm that you can out of it!

I would ditch the angled slot walls on the sides as well. Make those angled sections much shorter, and make them solid, with gaps top and bottom, and hangers behind.

What's your plan for the ceiling?
