244 Bass Trap with FlexRange Technology

GIK Acoustics was awarded U.S. Pat. 9,091,060 which encompasses our proprietary FlexRange Technology (FRT) membrane system. Backed by research, development and testing, FlexRange Technology encompasses our proprietary bass trap design while offering customers a true choice to control the frequency range that’s absorbed.  Without a membrane, bass traps are broadband.  With a membrane, bass traps absorb even lower frequencies while the membrane has less effect absorbing upper frequencies.

• FULL RANGE – The Full Range option is broadband in nature maximizing low end and upper frequencies to give a true broadband range of absorption. Full Range is an excellent option at controlling low end frequencies and is the preferred choice for early reflection points or when upper frequencies need 100% absorption.
• RANGE LIMITER – The second option has a built-in frequency range limiter. This option includes a membrane system which starts absorbing at a lower frequency but also has a cut off starting around 400Hz. Using the Range Limiter option ensures maximum low end absorption while retaining nearly 100% of the upper frequencies within your room. Ideally used when no upper frequency absorption is required/desired. The Range Limiter option is an ideal solution to make a small room sound larger, keeping life within the room. Additional charge per panel for Range Limiter option.

FlexRange Technology Test Results

GIK Acoustic Panels are tested and certified by the Riverbank Acoustical Laboratories (RAL) Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method ASTM C 423-02/NVLAP 08/P03 GIK Acoustics panels submitted to two standard acoustic test methods: ASTM “A” and “J” testing. For “A” testing the acoustic panels are placed all together flat against a surface and tested. “A” testing is the standardized testing method for the manufacturing industry. “J” testing simulates the recommended mounting of the product by the manufacturer. GIK tested two set-ups: 1) panels straddled in corners 2) panels spaced off the wall and mounted on stands. To our knowledge GIK Acoustics is the only company to provide data on both testing methods.

Riverbank Acoustical Laboratories (RAL)^TM has been accredited under the National Voluntary Laboratory Accreditation Program (NVLAP). The National Institute of Standards and Technology (NIST) administers the NVLAP program. NVLAP is comprised of a series of laboratory accreditation programs, which includes specific calibration and/or test standards and related methods and protocols assembled to satisfy the unique needs for accreditation in the fields of testing or calibration. NVLAP accredits public and private laboratories based on evaluation of their technical qualifications and competency to carry out specific calibration or tests.

Riverbank Acoustical Laboratories (RAL)^TM test methods adhere to ASTM standards. Formerly known as the American Society for Testing and Materials, ASTM International provides standards that are accepted and used in research and development, product testing, quality systems, and commercial transactions around the globe.
