I have heard them employed a few times and very effectively indeed. They are very expensive by the time you treat the entire room though vs say GIK acoustics. Also it is maybe slightly annoying needing so many stacked columns from an aesthetic perspective. SMT make some aesthetically pleasing and sounding products worth checking out too. Myself - I will be sticking with standard pro stuff such as GIK and vicoustic mainly cos a lot more affordable to achieve very good results.

I think you should invite Stephen with DaaDs, and Keith of Purite with his RPG and just try out in your room. These things are too variable and very few here have a room as big as yours to opine. Keith will try to measure your room and install DRC and tell you all valves are sh*t, but give him a smile and tell him to install just the RPG for trial. He is good that way.

I've put a bit of research into these. The advice from the UK dealers for my room is to treat the front walls and side walls with a combination of Daad4 and 3 panels, 12 in total, and a Volcano or Halifax Helmholtz resonator btwn spkrs, c£15k initial spend.

Then treat my sloping eaves w EcoDaads btwn seat and spkrs at 2' centres, adding up to 20 panels, another £10-11k.

And a final phase of treating rear walls and additional reflection points, maybe 10 Daads, £10k.

That's what happens when you ask for advice re an install in a room as big as mine.

Daad4 is £1k, Daad3 is £750. Phase One would be to have the five lots of 4's in front wall corners & front wall reflection points & front wall midpoint, w three lots of 3's stacked, and four no. 4's at side wall reflection points, Volcano or Halifax mid Zus.

Phase Two is to cover the 12' of eaves both sides w double stacked EcoDaads, amounting to 20 in total.

Tbh, cost is prohibitive when in comparison, for half this price I can combine GIK Gotham Quadratic Diffusors in a 4' x 4' panel on central front wall & side wall reflection points & eaves, and ASC Tube Traps or PSI AVAA units to front corners.

Cheers all. Should get a variety of Daads to play with week after next - will report back (not RRP BTW).

RPG website looks a bit impenetrable, too many choices.

Ked, that's not possible, you're my best friend. The love is palpable.

Actually, we've been in discussion since he's a dealer for the PSI AVAA electronic bass traps, and he's kindly offered me the tools to measure my room.

However, I'm more interested in diffusion than I am absorption, and I can only see this being set by ear.

That's why I'm veering twds predominantly diffuser panels on front wall (central plus reflection points), side wall and eaves reflection points, and a couple of front wall corner bass traps, ASCs or AVAAs.

I think "dead" is really a typo for "Daad".

My issue is that GIK absorbers at my side wall reflection points indeed deadened my sound too much.

Only have GIK corner bass traps now.

I'm wary that if Acustica are more absorption than diffusion, they won't be for me.

I am aware of that. Thanks for diffusing my joke

Ked, I'm sure you'll puff yourself up again soon enough.

Sorry, it is the best audio treatment site I have ever seen - complete data sheets properly measured of all their products and guides how to apply them. Surely they not include pseudo guides to teach you how to treat your room.

I have experience with their bass traps, diffusors, diffractals and abfusors - long I bought all the acoustical treatment of the Cello show room in my country when it closed down.

I always recommend reading this Keith Yates article on acoustical diffusion https://keithyates.com/a-matter-of-diffusion/ . But remember that rooms and speakers differ a lot!

The key point concerning diffusion is that a diffusor should diffuse uniformly along its working bandwidth - most cheap products show peaks of reflection and absorption and have very small bandwidth.

People with great experience ( I can't nominate them, sorry) told me that the materials to deal in acoustics for "serious" high-end rooms are RPG are STC - although with STC you depend on them to make the project, they do not supply enough specifications of their treatments.

Francisco, I'm not doubting the efficacy of their products, just the range of choice. Diffusers alone run to nearly half dozen.

How to choose?

No experience with them, but they look much more elegant than ASC tube traps. As far as I could see they use a micromesh plate type absorber / diffuser and fiber glass absorption - an interesting system. Does any one know where we can find a price list of their products?
