Overview

FlexRange Technology offers customers a true choice to control the frequency range that’s absorbed:

Effective absorption from 80Hz to 20kHz

Choose your bass trap without a membrane, and your bass traps are broadband bass absorbers. Choose to add a membrane installed and your bass traps absorb even lower frequencies. When used in recording studios, cymbals are crisp and clear while the bass kicks!

Our proprietary Range Limiter membrane system allows the 244 Bass Trap panel to absorb up to 50% more low end (below 60Hz) and retains 75% more high end (from 400Hz and above) versus the broadband Full Range option.

The dimensions of the 244 Bass Trap with FlexRange Technology allow the panels to be used in multiple quantities to absorb as much bass as possible without over absorbing the high end, which leaves life inside the room.

Specs

Bass Traps Flexrange Options Full Range Range Limiter and Scatter Plate

Core

The 244 Bass Trap’s 5.25″ thickness combined with the rigid fiberglass core provides twice the low end absorption over similar foam-based products.

Design

Patented design utilizes a two-frame system and built-in air gap which increases low end absorption with 3 options:

Full Range – without a membrane, bass traps are broadband
Range Limiter – with a membrane, bass traps absorb even lower frequencies while the membrane has less effect absorbing upper frequencies
Scatter Plate – Optional built-in Scatter Plate for an even balance of absorption, diffusion, and scattering

FlexRange Technology

GIK Acoustics was awarded US 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.

GIK Acoustics 244 Bass Traps in Most Audio Post

“GIK Acoustics products do a remarkable job at creating a great, early-reflection free sweet spot for the engineer and controlling bass. The panels and bass traps have turned an acoustically challenging room into a perfectly workable listening environment.”

Ivo Witteveen / co-owner MOST Audio Post, Amsterdam

Applications

The 244 Bass Trap with FlexRange Technology hangs truly flush on the wall using an integrated wire on the back and can easily be mounted straddling corners (recommended) as a corner bass absorber or as a cloud on the ceiling as hanging bass traps. The design of the 244 Bass Trap with FlexRange Technology allows it to be used in multiple quantities to absorb as much bass as possible without over absorbing the high end, which leaves life inside the room.

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.

ADD BUILT-IN SCATTERING / DIFFUSION

Cross Section illustrates how Scatter Plate is built-in to products

Broadband treatments offer great performance with an attractive price and when coupled with diffusion and scattering, can give your room a completely balanced sound throughout, without over-dampening high frequencies.

The GIK Acoustics built-in Scatter Plate option allows even decay time from low to high frequencies while providing the necessary space for absorption to flatten the frequency response. Read more about the new GIK Acoustics Scatter Plate here.

After adding products to your cart, you can then select Scatter Plate from the Diffusion Products menu and have them built into your Acoustic Panel or Bass Trap for only $49.00 per panel.

The GIK Difference

There’s a difference between a GIK Acoustics product and all others on the market.

The U.S. Patent & Trademark Office issued utility patent US 9,091,060 for GIK’s unique, proprietary design of its acoustic absorbers. The patent covers the design and construction of GIK Acoustics’ 242 Acoustic Panels, 244 Bass Traps with FlexRange Technology, and Monster Bass Traps with FlexRange Technology.

In addition to our patent, we separate ourselves from other acoustic treatment manufacturers in 6 primary areas

quality

GIK Acoustics products are beyond simple do-it-yourself panels that are found on the market today. We start with only the highest-quality materials that will not sag or leak over time, then we build every panel by hand employing a unique two-frame system.

Unlike other companies who use inexpensive materials, GIK Acoustics panels are crafted with quality insulation material, fabrics and hardwood plywoods. We start with absorptive insulation material that is intended for room acoustics – not cheap mineral wool whose main purpose is to insulate a ship’s engine room.

We then use carefully selected hardwood plywoods – not cheap imports – to construct our frames. The difference and chief advantage is dimensional stability. Crossbanded layers and balanced construction mean that hardwood plywood won’t shrink, swell or warp as much as lumber. To finish our panels we offer an array of fine fabrics – from our standard 9 options to the full line of Guilford of Maine panel fabrics.

GIK Acoustics products are not only Greensafe, but they carry a Class A fire rating which means we continue to provide our clients with the safest most effective products available. The Class A fire rating means that GIK Acoustics treatments have received the highest rating possible under the ASTM E84, a test used by code officials and regulatory agencies in the acceptance of interior finish materials.

Our team of professional builders handcraft each acoustic panel, bass trap and diffusor to exacting standards ensuring the most attractive, effective and dependable products. The difference is our customers are secure in knowing they receive the very best made-to-order acoustic treatments available.

value

Dollar for dollar, GIK Acoustics’ products absorb more sabins (sound) than any other product on the market. We provide our customers the most cost effective solution to make every space sound it’s best.

GIK Acoustics Panels are tested and certified by the Riverbank Acoustical Laboratories (RAL) to provide the most accurate information on the results you can expect when you purchase our products.

Our exceptional cost-to-benefit ratio means our customers do not over-buy or over-treat a room to get results.

Innovation

Over the past 10 years, GIK Acoustics has pioneered a number of acoustic treatments that you can’t find anywhere else. From the Tri-Trap Corner Bass Trap© to our Soffit Bass Trap© to the built in Scatter Plate, GIK continues to innovate.

After a year of research & development, in 2013 we introduced FlexRange Technology – our unique, proprietary system for providing the best in bass trapping and low end absorption.

In 2015 we launched the Alpha Series, a line of acoustic panels and bass traps with a wood face which has a mathematical sequence of slots for one-dimensional scattering / diffusion. The Alpha Series literally changes the face of acoustic panels and bass traps by beautifully combining absorption with diffusion and enhancing any room both aesthetically and acoustically with superior quality, high-performing, and stylish room treatments.

GIK Acoustics is also proud to have launched creative, unique products such as: the multifunctional PIB (Portable Isolation Booth), the decorative and effective Impression Series, and the striking, precise Gotham N23 5″ Quadratic Skyline Diffusor.

We are constantly innovating, so look for more solutions and creative treatments from GIK Acoustics.
