Here's my room

Well, including the hallways and attached kitchen I'm over 2500 ft3.  I can post the exact dimensions or a drawing later.  I'm pretty taxed on treatment but currently I have 12 4" panels, 10 2" panels and 2 6" panels made of 8lb/ft mineral wool.  My ceiling, side, front and (partial) rear reflection points are covered.

I've attached two pictures - the front (behind the speakers) and left side (semi-glamour shot) with the blue panel on my right side being a 6".  You can also see the hallway there above (behind) the keyboard.  

Conceivably I could build more treatment.  I could possibly add 7 or more bass traps.  

For clarity, the patterned one and all the blue ones are 4" with the exception of two of them which are 6".  The red ones are 2".  

I have some 2" laying on top of some 4" to make 6" panels in the corners since that gave me better measurements.  Also, all of my 2" panels are spaced 1" off the wall. Naturally my thicker panels are across corners.  

I should mention that the main purpose of this room has been critical listening, production, recording and mixing in that order.  Of course I want the best room possible but I'm not recording anything delicate for the most part; usually vocals or the occasional acoustic guitar (rarely).  Point being I would just like to be able to mix my own stuff.  That would be the most demanding application.  Since I'm relatively new to audio and music production I'm not sure I can also expect to master in here.  I'm mostly making computer rock/electronic music.  

This might sound silly but I was afraid of over-treating my room.  If you think adding more panels might help then I'm in but only if the result justifies the cost in labor and materials.  

At night I can get a minimal reading of around 50dB on my radio shack meter C weighted, slow ambient noise.  Therefore during the day it's much louder.  By no means is this an ideal work environment.  That being said it's all I have for now.  Any education I get here will only pay dividends later though I suppose.  99% of the time I'm listening on my mix cube which is very band-limited as you surely know.  It's just that when it comes time to mix I need to have that bass correct.  

That all looks fine, and having a "stepped" rear wall helps the LF response by breaking up those reflections. As usual, the solution is always more bass traps.

Hey Ethan, do you think it'd be a good idea to suspend my RFZ panels closer to my speakers to create a "listening box'? Sort of like a portable vocal booth but for my nearfields.

In the same vein, my cloud absorber is about a foot off the ceiling as opposed to spaced an inch or so.  I know spacing affects the effectiveness of the absorber but I didn't see anything in your articles about greater spacing for the thinner panels.  

Thanks,

Michael

So I just reread your articles. It would seem that orienting my desk to command the flying V shape would improve symmetry. It also says to give as much gap as is practical for your panels so it would make sense that suspending my treatment would be beneficial.

I'm just curious whether you advise reorienting the room, suspending RFZ panels and possibly repositioning my treatment. If I had angled side walls would I even need left/right absorption?

Thanks

LOL, so many questions, so little time. Yes, if you bought my book I'm pretty sure all of this is explained. But I'm glad to help even if you don't buy my book.

Don't set up facing a corner.

The theoretically ideal air gap is equal to the panel thickness. So if an RFZ panel is 1 inch thick, a 1-inch gap is perfect. But you can have an even larger gap and still benefit, especially if the panels are 3-6 inches thick. So a 4-inch panel can be 8-12 inches away and absorb even lower than when 4 inches away.

Your room is not square since it has that extra area in the back.
