    Managing reflections from wall surfaces in larger rooms requires products that have large amounts of surface area to absorb those reflections. Another design requirement is that air must move across both sides of the technology.

    Air movement across both sides, reduces the amount of units and surface area required within rooms to reduce the energy level of the reflection. The vertical or horizontal orientations allow you flexibility in positioning the units to fit into existing room aesthetic and space requirements. Mounting hardware is provided.

    Our foam ladder, is a wood framed unit that surrounds our full sheets of our 2″ thick foam. It measures 57″ x 4″ x 78″

    Tired of working with dead sounding foam? Want your vocals and music to shine without losing their emotion and energy? Then our unique Acoustic Foam is for you.

    More cells with better shapes produce more absorption below 500 Hz. In fact, we absorb 30% at 125 Hz. and 63% at 250 Hz. reaching 100% at 500 Hz. We went after the bottom half of the existing absorption curves to produce a foam that has a smoother absorption curve that goes lower where our vocals start and ends with a smoother, more gradual rate and level of absorption.

    You get:

    • More absorption below 250 Hz. than standard foams. It absorbs 30% at 125 Hz., 63% at 250 Hz. and 100% at 500 Hz.
    • A smoother absorption curve from 125 Hz. – 500 Hz. than any other foam on the market. This range is the heart of your vocal and music frequencies.
    • A technology that manages side wall reflections so you can hear the direct sound from your sources and not the reflected energy of your room.
    • A box of 4 foam tiles with each tile measuring 25″W x 18.5″H x 2″D

    Suspended ceiling tiles are typically compressed powders and fabrics. There thickness is at 1/2″ so between the tile composition and the small thickness, absorbent coefficients below 500 Hz. are hard to come by.

    Frequencies below 500 Hz. are where our vocals lie in frequency response. In fact, male human vocals can start as low as 100 Hz. This is the reason why a standard ceiling tile provides little assistance when you get a room full of people.

    To keep the look strength, rigidity, and cost of the Armstrong ceiling tile for suspended ceilings, we have taken the standard and decades tested 1/2″ acoustic ceiling tile and added our proprietary 2″ foam technology. We center a 18″ x 2″ x 18″ piece of our 2″ thick foam on the 24″ x 1/2″ x 24″ Armstrong white ceiling tile. Foam is grey and Armstrong tile provides the white 3″ recessed border. Ceiling tiles come in 24″ x 24″ or 24″ x 48″

  • The ACDA-12 STUDIO has the same performance as our 1,350.00 units which are only different in finish.

    ACDA 12 Riverbank Acoustical Labs Testing Results

    Finish is a three coat process of clear coat to protect the commercial grade exterior material. Carbon technology inside the unit and our 2″ foam technology featured upon the face of each unit.

    The ACDA-12 STUDIO is a frequency specific absorber that starts at 30 Hz. and goes through 50 Hz. It does this journey with 35 % absorption at 30 Hz., 63% at 40 Hz. and 100% at 50 Hz. This unit is a low frequency, very powerful, “sponge” that you can use to absorb 30 – 50 Hz. unwanted energy within today’s smaller studios.

    Live rooms can benefit from this absorption range. Control rooms will require it if dimensions are below 20′ and that is a common concern in today’s smaller rooms. They work well for kick drum unwanted low frequency pressure issues.

    Units are 30″ w x 60″ h x 16″ d, on casters, and weigh 150 lbs. Units are shipped to your studio on pallets. Two versions with and without fabric face are available.

    Speaker cabinets are really miniature rooms. As your diaphragm (speaker) moves inside the cabinet, reflections and unwanted low frequency pressure issues inside the cabinet color the sonic energy that is then released through your speaker drivers and into your listening room. These sonic coloration’s take many forms.

    First, there comes the vibration or structural issues of the cabinet’s themselves. Everything that moves makes noise, Your drivers move back and forth and are attached to the cabinet. The cabinet takes this energy and then transfers it to the floor, so the floor can start moving. You now understand vibration (noise) transmission pathways.

    Low frequency, unwanted, room modal issues are presented within our speaker cabinet are in direct proportion to the speaker cabinet size and volume. Reflections from the speaker cabinet (room) are bouncing around inside the cabinet cavity. Where does all this over pressurized and time delayed reflected energy go? It goes through the drivers and then out into your room. Low frequency energy radiates at 360 degrees from speaker center point.

    To minimize the transmission of vibration, lower frequency pressure issues, and internal cabinet, time delayed reflections that come through the low frequency driver in the cabinet, we use our carbon technology in our SCP which stands for Speaker Carbon Platform.

    Inside the 6″ high platform, which is custom made to your be 1″ larger than your speaker base dimensions, lies our carbon technology which acts to absorb low frequency energy through the diaphragmatic process and then to minimize the transmission of vibration (noise) to the floor through transmission loss to the floor. Noise reduction whether through internal cabinet treatment or vibration energy dampening means more music in your room.

  • subwoofer absorber platform
    subwoofer absorber platform

    Sub woofers generate a lot of low frequency energy that fills our rooms. Most of that energy will simply not fit into our small rooms. A 12″ driver produces 2 dB more energy than a 10″. All of this energy must be managed and the best location to manage unwanted low frequency pressure is as close to the source as possible.

    Our sub woofer carbon platform SWCP provides broadband absorption from 30 – 200 Hz. Broadband absorption that averages a 25 – 30% rate of absorption at the levels from 30 – 200 Hz. where sub woofers produce their energy. This rate and level of absorption is the same as our ACDA-10 unit (visit ACDA-10 page).

    The SWCP stands 18″ high and the dimensions are made to correspond to your width and length. Units are on casters, so positioning the sub through the room tuning process is facilitated. A platform height of 18″ is always welcome in any room size and volume. The average weight is 55 – 75 lbs.

  • Sound Absorber platform for pianos
    Sound Absorber platform for pianos

    *price per section

    Pianos radiate energy in many directions. They radiate from the piano bed to the floor, from the bed to the ceiling and out the wood sides of the piano. If the lid is left on, then you have another series of reflections from the lid to the bed and then out towards the front. How do you manage all of those radiating sources of energy. It is difficult. That is why you do not hear many quality piano recordings.

    Low frequency absorption is achieved through the use of our carbon technology. All energy below 100 Hz. is treated with absorption through our carbon diaphragmatic process. Since the piano bed (speaker) is placed close to a boundary(floor), low frequency energy is magnified and proper rates and levels of absorption must be applied just as with placing a hi-fi speaker close to a wall.

    Middle and high frequency unwanted reflections from the floor to the piano bed are also reduced to minimize comb filtering. Comb filtering occurs because of the back and forth travels of sound energy from the bed to the floor and then back from floor to the piano bed producing a series of unwanted reflections. Our 2″ foam technology is installed on the top of the unit facing the piano bed to minimize the strength of this unwanted energy.

    To deal with two main issues comb filter and SBIE, we have created our Piano Carbon Platform. It is a smaller version of our ACDA-10 unit with a higher resonant frequency and unit height of only 6″. Two units fit most pianos and are rolled under the piano bed.

    You can choose a complete platform to position your whole piano on or individual modules that fit between the foot pedals and the far leg.

    Numerous fabric options are available.

  • The CDP (Carbon Drum Platform) is a drum platform which uses our carbon diaphragmatic technology to absorb the lower frequency energy from the kick and tom drum all the way up to the snare. You can achieve a large tight and defined drum sound, using our Carbon Drum Platform CDP.

    The CDP comes in three sizes:

    • 8′ x 8′
    • 10′ x 10′
    • 12′ x 12′

    Please read the full description below.

  • Many times in our studios we have a need for both diffusion and absorption. Bringing in separate units is not easy and definitely not cost effective. With our diffuser absorber studio (DAS) units you have both diffusion and absorption both in one unit. The unit is on casters so mobility and positioning is much easier than with free standing units.

    Diffusion can add air and separation to your instruments and vocals. A properly diffused sound field is a necessity in today’s recordings where absorption is used improperly. All rooms require the ability to absorb access low frequency energy no matter what the room dimensions and volume. Both of these features are now combined into one portable unit.

    Units are clear coated commercial grade MDF. This simple finishing technique is cost effective and seals the unit from moisture. Casters are rated at twice the load they are carrying and have double wide wheels which insure the ability to position them easily in tight places. Fabric color and texture options are numerous.

    There are three diffusion options you can work with. The quadratic diffusion options are based upon prime numbers 7,11, and 13. The higher the prime number, the more octave band coverage. especially at lower frequencies.

    • The DAS – 7 offers diffusion from 850 – 3,450 Hz. and our carbon absorption from 30 – 400 Hz. Units measure 24″ w x 60″ h x 16″ d and weigh 225 lbs. on casters.
    • The DAS – 11 offers diffusion from 375 – 3,450 Hz. and our carbon absorption from 30 – 400 Hz. Units measure 24″ w x 60″ h x 23″ d and weigh 250 lbs. on casters.
    • The DAS-13 offers diffusion from 275 – 3,450 Hz. and our carbon absorption from 30 – 400 Hz.Units measure 27″ w x 60″ h x 24″ d and weigh 275 lbs.on casters.

  • The CSS is designed to accommodate rooms of different heights, widths, and lengths. The height can be adjusted from 8′ to 10′. The width can go up to 18″ and the length is achieved by “stacking” individual units together. It is truly a room within a room that you can assemble without any construction materials or crew. Two people can assemble within the existing room.

    To determine what size you will require in your room, take the measurements of your room and reduce the width and length by 12″. This will be your width and height measurement for your CSS. The height of the CSS is determined by reducing the existing height dimension of the room by just 3″. We want to maximize height as much as possible. Reducing the height dimension by 3″ from your existing room height is a good start.

    Each CSS module is 2 units wide and measures 54″ in width. The first units installed will be the ACDA-12 modules. They will go around the edge of your room where pressure areas are the highest. After the border is achieved with the ACDA-12 units, there is a combination of the ACDA-10 and diffusion units. Actual layout will be determined by room usage and room distances.
