Foam Frame Panel

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.

Our carbon technology is now available for use in small rooms that don’t have the physical space requirements for our ACDA series to absorb lower frequency energy. Our carbon technology that has become so popular with our low-frequency product line is now available in panels that are not as deep as our ACDA units. With the same smooth frequency response starting at 40 – 60 Hz. and going through 6,500 Hz. it is a smooth low-frequency absorbing tool for absorbing unwanted low-frequency energy along the boundary surfaces in small rooms. At a maximum depth of 8″, it won’t take up much wall space and gives you lower frequency absorption down to 40 Hz.

With carbon technology, you achieve a smooth absorption curve that is smooth in rate and level with a special quality of clarity that is not offered with foam or other absorption technologies especially the building insulation types that dominate the industry. If you are looking for a more natural rate and level of absorption that does not over absorb at certain frequencies and under absorbing at others, our carbon and foam technologies will give you that linearity you need.

Our 24″ w x 6″- 8″ h x 55″ l unit is finished in a painted or wood case and your choice of wood and fabric color and texture are available. Units weigh 75 lbs and are designed to be hung on a wall just like a picture would be.
