  • Windows are always an issue when it comes to music presentation or recording. There is nothing worse than the harsh, brittle, glare that comes from sound energy reflecting off of glass. Unfortunately it is a necessary evil in today’s rooms especially rooms that are used for music and living at the same time. Windows need to be uncovered so light and viewing can occur, along with an option to cover them when music is played or recorded.

    There are two methods that you can use to deal with the harsh glass sound. You can use diffusion or absorption. The SFP or sliding foam panel is a way to use absorption to cover the glass and have sound energy strike sound absorbing foam instead of the glass. A wood frame with our foam technology inserted within the frame produces a “ladder” look and appearance that slides back and forth on a track assembly.

    The “ladder” assembly can be made to any height that works with out standard foam sizes of 18″ x 25″ . You can have 2 sections, three, or even four to work with larger sliding glass patio doors or any other window size that compliments these measurement guidelines. Foam is grey and the “ladder” or frame assembly is available in different wood options.The track installation is straight forward and easy to install. Adjustments in the track assembly are easy to use and can assist you with fine tuning how easily they move and slide into place.

  • 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.
    • 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.
    • Technology that manages side wall reflections so you can hear the direct sound from your sources and not the reflected energy of your room.
    • Box of 4 foam tiles
    • Available foam sizes: 25″ x 18.5″ x 2″ | 25″ x 54″ x 2″ | 37″ x 54″ x 2″
    • Studio foam that lets your vocals and middle range instruments pop.
    • A technology that does not drain the life out of your room like so many other foams.
    • Foam that finally lets you hear the intimate timbre of the singers voice in every recording. Finally you will have a room that is an acoustical pleasure to record in and very much in demand.
    • A foam that comes with variable installation options.


  • 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 3″ x 77″

  • 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.

  • 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.

  • 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.
