Beautiful Vicoustic's flagship Wavewood panels for room tretment. Anyone?

I'm building a new listening room (new home) which has a limited size (interior-16'w X 19.5'l X 10'h). 

In my prior listening room which I had 39,000 LPs/78s on solid MDF shelving cabinets and on the floor and CDs in steel cabinets, with up to 11.5' high vaulted ceilings, multi-pane casement windows at first reflection and front wall, dual layers of drywall, etc.  Not a great sounding room with plenty of slap echo.  I treated the room with 2 pairs of Shakti Hallographs and 32 Synergistic Research HFTs.  The slap echo was ameliorated during music playing and sound frequency spikes were diminshed (greatly).  No problem with bass though.  This current room sounds better than 95% of the 100s of rooms I've heard at audio shows and audio salons.  

In the new listening only room (storage in an adjacent room), I'm building out the exterior walls with carbon filter absorption panels which are extensively built products unlike GIK cheap materials.  What looks like an interior room solution room is quadradic diffusion along the front and rear walls.  I doubt that the Stillpoints Aperture (I use only Stillpoints isolation products) would accomplish the same as these big, well built all wood products 
https://www.acousticfields.com/product/sounddiffuser-acousticdiffuser-qd13/   Yes, they are expensive, but once installed, don't have to be moved or augmented.  If I get to build my larger listening room, I would move them there.  The goal of the QD is to smooth the frequency distribution resulting in a room sounding twice as large as it actually is.  That's what I've been told.  Also, no more drywall on interior facing walls, only natural finished wood (plywood).  I anticipate that I will be able to duplicate my 40% current larger room with my smaller new room and add smoother mids and highs.  

The room acoustics is half the sound.  So many forums are concerned with small differences in sound for high priced equipment and tweaks.  I'm starting with the acoustics first.  I already have the equipment.

@fleschler nice, i was thinking about those wooden things, especially if they could be made locally (DIY), but in terms of design some of them are a bit ugly for a living room, but great for the recording studio.

Why i have mentioned the Vicoustic is because of the $50 option of the Room Analysis they are offering for everyone, based on 3d model of the actual room. So i got it from them.

But i want to double-check it using a trick with a mirror (see the next link)

For most of us (not specialists in room treatment) it’s important to understand the basics first. Long time ago i’ve noticed that the bass responce is way different in the middle and near the rear wall in my 33 square meters room. This video about standing waves is so funny. So the standing waves ... damn.

Something that i need in my room to treat it good:

1) Vari Bass or Super Bass Extreme or Premium

2) then Wavewood Diffuser and Wavewood Absorber

3) another Round absorber for ceiling and walls or Flat one as an alternative

4) and finally Bi-Dimensional Multifuser for ceiling.

In my sistuation everything must be WHITE color in my white room.

Would be nice to read more comments from people who already using those panels.

@chakster  You have a reason to use specific color and materials for your listening room, like my living room requirements (only SR HFTs permitted for good reason as it's a formal room with my small audio system. 

My new room is being built into a double garage; unfortunately, as the City of Los Angeles passed an anti-mansionization ordinance last year cutting in half the buildable lot area to 20% for RA zoned lots (most big lots in the City) over 20,000'.  They permitted large homes at 45% of the lot area for R1 zoned lots above 7,500' and 50% for smaller lots, which allows large homes on small lots still.  Super stupid planning as it halted development of new large homes on large lots.  

So, I can design the room freely as to color scheme and materials.  I'm going with carbon filters in the walls/ceiling for bass treatment.  Dennis Foley of Acoustic Fields did an analysis and will supply me with building plans, installation instructions, etc. for $2,500 (50% rebated towards the purchase of materials).  Vicoustic's $50 analysis appears to be similar but they give basic information and not as much support.  

@chakster ,

The Aperatures are diffusion, resonator & absorption in one relatively small panel. If I was privy to the internals, of coarse I could make my own. As far as I know, no other manufacturer has this type of 3 in 1 product. I did not pay any where near $800 for mine. Yet, still they aren’t cheap.They are however, very effective!

Hey @slaw i am not an expert, but when a single panel is a combination of absorber/diffusor exactly like this Wavewood it depend on the effective fequency range. This particular panel is also act both as an absorber and dffuser and effective in treating medium and high frequencies (also can be used as bass traps in the corners).

In the beginning i was thinking that i can only use this universal panel for my needs, but after i got the actual 3D model of my room from from acoustic specialists i realize that separate panels such as primary bass traps or multifuser are much more effective when we can to cover a wider frequency range to make a room much closer to the ideal acoustic room. Unfortunately one multifunction panels is always a compromise. Also bass traps can not be small.

They made a similar looking panel Wavewood Premium which act primary as diffuser comapred to the different Wavewood absorber/deffusor/basstrap. There is a graph for each to see the frequency range they are covering, they are different.

I think it’s impossible to make one panel to act like 3 different panels effectively.
