Thought some one might want a crack at this one

While looking into absorbtion I came across this little fella.

On the site are a some pics, info and a few PDFs. If they work as claimed, 600 euros for 8 aint that bad, but as I don't get how they work, I thought someone might like to check them out.

If you have not heard of them please meet the

Acousticone!

Just thought some here might find them interesting

While not taking hours to dig into the theory of this device, I get a feeling it works like this.... (A Ceiling Cloud)

In Michigan there are 2 ampitheatres we hated doing live sound in. Pine Knob (DTE Music Center) and Chene Park (also known as Pain Park cuz you hated to have to mix in this place)

Well a few years back the venue owners decided to "fix" the acoustics of this ampitheatre (Pine Knob) with ceiling mounted baffles. Much Like Johns bass Trap hangers. It greatly reduced the reverberation of the hall, made it much more tolerable/mangeable to mix in this place.

Last year they did the same with Pain oops Chene park Finally calming down the 6 second reverb in that place and making the sound more manageable.

However, I can't see this product doing for a Studio Live room environment what is totally needed. Smoothing out reverb time AND correcting the EQ of the room to a more neutral character. Which Is accomplished here with angled walls 1st and foremost.

Here were the side effects of mixing in the park with the baffles.

Yes, Less, Much Less reverb, not as much sound bouncing around in the rafters, but oops, the color of the room suffered. These rooms became very midrangy to mix in. The top end had to be boosted from an otherwise FLAT box to compensate.

Now we are talking EAW 750, Turbosound flashlight/floodlights.

While I have yet to mix on a Line Array in these parks Which should prove interesting, the reduced reverb time is the Major advantage.

Not sure 600 Euros is a great deal at the exchange rate that is about 707.28 USD

I am pretty positive you can get a more effective ceiling treatment made by your self for much less, Ceiling clouds for example. which is basically what these aluminum and paper cones are.

Just my .02. I am sure one of the engineers will be along to give you the "math" as it were.

One last thing. AFter I typed my response I looked at their RT60 chart again. Notice that 500 Hz and 100Hz stand out in this otherwise smoothed reverb time chart.

Still midrangy and the low end is not dealt with.

It just looks like a perforated panel, folded into a cone shape, and filled with absorption material - i.e. a Helmholtz resonator. Sort of a clever design, but certainly not rocket science.
