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.
Speaker stands do many things for us. First, they separate the vibration of the speaker cabinet from our desk. Second, they allow the speaker to be the correct height. Third, they can provide broadband low frequency absorption in the area of the room that has the highest unwanted low frequency pressure. The front wall where our speakers are located is always an area of high frequency pressure.
Achieving good sound in your room is about doing a lot of little things in the correct order. Reducing the vibrations of the speaker cabinet by setting it on a platform that is designed to absorb excess vibration and air born energy allows for the driver and the crossover to work together to produce energy without those cabinet resonances interfering. We use a damping compound layer that your speaker will sit upon.
Using our carbon technology we achieve a platform that reduces cabinet resonances and also provides needed broadband absorption in the front of our rooms. This is the same technology used in our ACDA-10 and ACDA-12 units. Stands can weigh up to 50 lbs for the 12″ x 12″ version. The 12″ model will absorb from 30 – 50 Hz. and the 10″ deep unit will have broadband absorption from 30 – 200 Hz. The 8″ platform will start at 40 cycles and go through 200 Hz.
Three widths are available. We have a 8″ x 8″ , 10″ x 10″, and a 12″ x 12″ model to accommodate different speaker widths and depths. Heights usually run around 30:” but you will have to tell us what height you desire. Finish is black paint enamel with 5 coats of paint hand sanded and clear coat sealed. Need a special width or height, just let us know.

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.
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 10″. Units have non stick surfaces on both sides and are placed side by side to form a platform.
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.
Theaters need low frequency absorption everywhere. You have multiple, full range, mono sources producing lots of energy in short bursts at all frequencies throughout the room. Low frequency modal issues are everywhere and the last place you want them is at the seated positions where people view and listen. Attack and decay rates must be treated for so that “bass boom” doesn’t overwhelm the seated area.
With the TSRP – Theater Seat Riser Platform you can manage all frequencies from 30 – 200 Hz. in the most critical area of the room. The platform is modular and comes in sections that are 2′ x 1′ x 4′. you build the square foot coverage your number of seats require. We also can assist you with building the platform into your existing structure. Plans are available and we can assist you with the carbon technology that goes inside your platform.
The TSRP comes in three sizes:
- 8′ x 8′
- 10′ x 10′
- 12′ x 12′
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:
- 6′ x 6′
- 8′ x 8′
- 10′ x 10′

Diffusers must be positioned at correct height in order to perform correctly. Our bases are designed to elevate the diffuser to the correct height to match your usage. Each diffuser height and width dimension will be adjusted to match your room.
Each diffuser base features our carbon technology to improve your low frequency absorption in either the front or rear of your room. Finishes can be selected to match your diffusers.
The ACDA-10 CSM (module) is a smaller version or our production ACDA-10 unit. It is a broadband absorber from 30 Hz. – 200 for lower frequencies and with our 2″ foam face, absorption is increased through 6,300 Hz.
With broadband low frequency absorption, you have a powerful tool that you can distribute across your ceiling system to deal with unwanted floor to ceiling pressure issues. Numerous wood and fabric texture and colors are available.
ACDA-12 CSM is a smaller version of our production ACDA -12 unit. This is a more limited frequency range starting at 30 – 50 Hz. It is powerful with absorbent coefficients of 63 % at 40 Hz. and 100 % at 50 Hz.
It is perfect for unwanted pressure areas around the room parameter. Numerous wood and fabric texture and colors are available.
