ACDA-10

Activated Carbon Diaphragmatic Absorber

What’s Different?

I invented the ACDA 10 and ACDA 12 Diaphragmatic Absorbers because I was unhappy with all the current products on the market that called themselves low frequency absorbers as they were nothing of the sort. I wanted true separation of bass sounds below 100h Hz, where the real magic in music happens, and nothing commercially available even came close to providing me with the sonic experience I craved.

So I took the low frequency absorber walls I had designed, built and tested over a period of 8 years for professional offices, and worked with my team on developing a free standing unit that could be moved around a room as desired. Within 2 years we had a rigid cabinet structure and design in place but I knew I needed a cabinet fill material that would compliment the cabinets performance if I was to achieve the performance level I needed to really tame room modes, not just pay lip service to the concept. My stroke of luck came when I discovered the activated carbon internal fill material quite by accident.

I was working late one night and was stood over the kitchen sink when I noticed the water filter light was flashing. Struggling to remove it, I decided to hit it with a hammer and out poured all these small black pellets. On closer inspection the pellets looked liked miniature meteors, each full of thousands of microscopic holes, so I realized that if these small granules were filtering water and air then maybe they would help filter sound!

Further research indicated that activated carbon has a huge amount of surface area per gram of material, 2,000 square meters in fact! And with all of this surface area packed into such a small amount of space, I now had the secret, powerful fill material ingredient that could provide the horsepower audiophiles and professionals require to manage bass energy effectively. 8 further years of research and development later I now give you the ACDA 10/12 units.

What Will You Experience?

  • You get pound for pound the most powerful activated carbon diaphragmatic absorbers available, in a free standing unit, in the world today, which gives you unprecedented attack and decay clarity in every bass note, so you can mix without second guessing and enjoy your music like you never thought possible.
  • You get 65 lb’s of activated carbon, 7 layers of constrained layer mass damping materials and two front walls in your unit which means you will experience a well defined, low end so your mids and highs will pop at you making your entire listening experience far more enjoyable as you open up a whole new dimension to your music.
  • You get low frequency absorption from 30 Hz. to 200 Hz. which gives you attack, decay, definition and tonal qualities, that you won’t have ever heard in your music before because of the way your room gets in the way. You’ll hear exactly what you want to hear when mixing without having to second guess your mix because of your room.
  • You get a moveable unit which can be wheeled in and out of your listening room or control room which gives you the flexibility to use your room in more ways than one without complaints from your partner as you can still return the room to its other uses when required.

The effectiveness of the box is exponential, the larger the room, the more boxes you need. But in the end the result is nothing short of amazing! Once you introduce the absorbers into the room, the effects are noticeable immediately.

With the sound absorber panels it’s changed my whole musical experience! It’s given me depth in my music listening. The musical experience alone is more listenable, the instruments sound more like instruments.

Diaphragmatic Absorption:
Time Tested And Proven

1. Dual Front Wall – The front wall in all of Acoustic Field’s diaphragmatic absorbers is not just a single wall. It is a dual wall structure that has been designed to increase the rate of absorption by increasing the level of energy that is slowed down before entering the internal cabinet fill material. With a dual wall face that is designed with sympathetic vibrational technology in place and having both dual wall, front panels that are designed with the proper density and air space between them to insure maximum movement in sympathy with each other, greater absorption rates and levels are achieved. When sound pressure energy strikes this dual wall, front face assembly, it is slowed down by a factor much greater than a single wall.

New And Improved Diaphragmatic Absorption

2. Stronger and More Rigid Cabinet – Cabinet rigidity and density has been increased using multiple layers of materials with different densities to insure maximum cabinet rigidity, so that the front dual wall construction is encouraged to vibrate. Viseo elastic compounds are used between each cabinet layer to insure that vibrational energy is minimized from the cabinet itself.

How our diaphragmatic absorbers work.

3. Activated Carbon Lowers Cabinet Q Value – The internal cabinet fill of standard building material, mineral fibers, has been replaced with activated carbon. Activated carbon is a fancy name for charcoal. Activated carbon has a high degree of porosity which contributes to its high rate and level of absorption over standard building type insulation. The rates and levels of low frequency absorption created by Acoustic Field’s activated carbon diaphragmatic absorbers have never been achieved until now for a commercially available product.

Features
The ACDA-10 is our flagship, activated carbon, broadband, diaphragmatic absorber with low frequency absorption from 30 Hz. – 200 Hz. The face of the unit can be used to support one of our foam absorber thicknesses or one of our mini-diffusors in our MDP line. Units are designed with rigid side and rear walls and a dual wall, front panel construction that increases diaphragmatic action. The inside of each unit contains our activated carbon filters which increase the unit’s Q value through acoustical compliance enhancement. This activated carbon filter process is unique to low frequency absorbers and is patent pending. Solid wood and paint finishes are available. Each unit measures 60″ tall, 30″ wide, and 16″ deep. Each ACDA-10 unit weighs 225 pounds.

Benefits
All rooms need low frequency energy control, unless you are fortunate enough to have a room that measures at least 30′ in one of it’s dimensions. The ACDA-10 is designed to be a broadband, linear, absorber targeting the 30 Hz. – 200 Hz. range. It is even effective at higher frequencies. With the ACDA-10 unit, you can also control unwanted middle and high frequency reflections through the application of one of our foam thicknesses, mini-diffusors, or a combination of both. You can now have broadband, linear, absorption from 30 Hz.- 6,500 Hz.

We stand 100% behind our product performance levels so we are happy to offer a 100% Money Back Guarantee if you are unhappy with the performance results, for any reason.

Enough With A Compromised Listening Experience

Other manufacturers didn’t think it was possible or worth the time and money going after the low frequencies we’ve gone after. They thought it was impossible to achieve in a free standing unit and, in some cases, changed the definition of low frequency so that their so called “bass absorber” performance matched their exaggerated definition. Well talk about moving the goalposts and trying to pull wool over people’s eyes. We aren’t having it and are calling it out now. Enough is enough.

Our low frequency absorption rates have been independently tested and verified by the World famous Riverbank Acoustical Laboratories. You can see their report here: ACDA 10 Riverbank Acoustical Labs Testing Results and the graph shows the absorption levels verified in the report.

ACDA-10 Absorption Chart

So if you’ve bought what you thought was a low frequency bass absorber and its not dealing with frequencies below 100 Hz., then you’re missing out on a world of incredible sounds and pleasure in your music. With the wrong room dimensions, you will actually not hear some bass notes at all, no matter how high you turn your system up! You might as well bury your speakers 2 ft underground such is the equivalent blurring of the sounds you’re missing out on in your music.

So avoid listening to thick and muddy bass for a minute longer. You’re missing out on so much more from your music than you could possibly imagine, which is no doubt leaving you frustrated by the sound from your expensive amp and speakers.

There’s no one size fits all when it comes to room acoustics. Your room is unique to you. If you see acoustic treatment analysis calculators on other sites, that’s all about marketing but no function. You need a live engineer to look at your room because there are too many variables in play to have a one size fits all solution. And any company that provides a one size fits all solution are just selling a bunch of band-aids that aren’t going to solve your problem. We're offering a REAL and FREE acoustic treatment room analysis, conducted by none other than Dennis Foley, our chief acoustics engineer himself.

    Hi my name is Joe Salvatto from Salvatto Sound. We are a company that specializes in boutique studios here in the New York City Tri-State area.

    I came across this product designed by Acoustic Fields. Its called the diaphragmatic absorber. I read about it and was very intrigued with its capabilities. I had the opportunity to speak with Dennis, it’s designer, and was convinced that it was definitely something we could use on our installations.

    It’s a rather small enclosure, 24″ x 48″, but it’s abilities are actually beyond my expectations. It has the capabilities to absorb frequencies down to the 30 cycle range.

    So far we’ve used it in one room and have the intensions of using it in our next two installations.

    Everything Dennis said it would do, its done and then some.

    I was happy to comply with the companies request which was, upon purchasing the plans online and also signing a non-disclosure agreement, we have to purchase the charcoal absorbers, which is the internal workings of the device, directly from them, which they actually provided to us with a rather timely fashion. It didn’t take too long.

    The effectiveness of the box is exponential, the larger the room, the more boxes you need. But in the end the result is nothing short of amazing. Once you introduce the absorbers into the room, the effects are noticeable immediately.

    This device has added a paint brush to my box that I never would have thought I’d be able to have in this small of an enclosure. I’ll be using them from now on and I’m sure once you get a chance to use them, so will you.

    This is Joe Salvatto from Salvatto Sound. Very nice to talk to you.

    This room was eight or nine months in the making but it’s the Acoustic Fields bass traps that really made this room sing. Now it’s really quite a musical room that’s the way I would put it.

    Because I’m in New York City, because I’ve been doing this for three decades, because I have a lot of Rockstar engineer best friends, you see them on the Mix Master Wyatt show, Chris Gehringer, Luca Pretolesi, you know all kinds of top engineers doing number one records in the country I get to move around some of the best rooms, really on the planet, and when they come up here they’re like “oh my gosh, this is amazing, you can hear everything in this room!”

    You can hear extremely well sitting in the client couch and its, you can hear amazingly well sitting in the mix position and we used to have something too where if you stood up you’d get a slightly different low frequency response that also has gone now.

    And I’m really happy to say, and I’m an endless fiddler, that it’s really in a place where I wouldn’t change a thing and when people come in, I had the musical director for Chris Brown’s world tour here yesterday who is out on Lady Gaga’s Monster Ball Tour, top, top producer musical director and he was like “this room sounds insane!” He was like “I haven’t heard a room sound as good as this in a long time”. And he gets also gets to walk in the top rooms.

    So I’m extremely happy with it. This room wasn’t done until the Acoustic Fields bass trap technology entered the room and then once we did exactly what was proposed by you Dennis the whole thing snapped into place.
    So I couldn’t, I really just, I couldn’t be happier.
