Why You Need Us

Real Low Frequency Absorption

For years, companies have been telling you that their products absorb low frequencies or as their literature says “bass absorbers”. This is incorrect for many reasons. Foam filled tubes or foam wedges do not have the physical makeup or characteristics to absorb any frequency lower than 100 Hz. It would take a piece of foam 11′ thick to absorb a 100 hz. wave. How can a foam wedge that is 12″ deep absorb anything other than frequencies above 100 Hz? The answer is that it can not.

Bracket Creep

For years we have had “bracket creep” in our graphs that show absorption performance. The definition of low frequency absorption has steadily risen. Low frequency absorption used to be anything below 100 Hz. Now, the literature is full of “bass traps” that say they absorb bass. Unfortunately due to raising the bar, I have seen products that advertise their technology as a bass absorber with absorption around 400 hz. Do not be mis-led by these claims. Do your research and stay informed. When you look at their test results they either do not have any or just claim that their product absorbs bass energy when in reality it cannot due simply to the laws of physics. Remember those? Those are the rules and guidelines we all in this business must play by.

Low Frequency Management Need Greater Than Ever

Our activated carbon absorbers really do what they say and we have the test results to verify their performance. Low frequency issues are more of an issue than ever before. Our smaller rooms, due to population creep and costs, manifest more low frequency resonances than ever before. The need for low frequency control is more important than ever. Look to a technology that is time tested and field proven to get real results.

Riverbank Labs Test Results

When our ACDA-10 and ACDA-12 units were sent to Riverbank labs for testing the engineers had to run the tests three different times. They could not believe how a product 10″ or 12″ deep could absorb so much low frequency energy in such a small amount of space. They wanted to cut them open to see what was inside. Here are those same ACDA 10 Riverbank Acoustical Labs Testing Results and the ACDA 12 Riverbank Acoustical Labs Testing Results that so shocked them.

This is real technology that takes an industry standard, sound absorbing technology, namely, diaphragmatic absorption and improves upon it by a factor of 10. They really work and really absorb lots of bass energy. You will hear the difference immediately and be startled by the difference.

Eight Year Development Cycle

Our foam was developed because we needed more control with our vocals in the Class A office buildings we were developing. We needed more absorption at frequencies below 200 cycles which is where both male and female vocals lie. Current foams at the time and still today, absorb 5% at 125 Hz. and maybe 10 % at 200 Hz. Neither absorption amount is enough when it comes to controlling the reflections in our small project studios, home theater rooms, or personal listening environments, especially with vocals.

Greater Lower Frequency Absorption

Our foam technology absorbs more at lower frequencies and with this increased level and rate of absorption, we get amazing clarity and definition with our vocals. There is a balance and separation you have never heard before because your existing foam can not get out of its own way. Competitive foams got the top half of the absorption curve correct, but they missed the bottom half which is the most important. Other foams are simply not designed the way ours is to perform at those lower frequencies. By going lower in the beginning, we produce a smoother absorption curve which not only improves vocals but does wonders for musical presentations. All music likes a smooth and balance absorption curve, so every instrument and vocal can be heard. Once you hear the difference, you will be completely convinced.
