Cross section illustrates Scopus Tuned Bass Trap design

The GIK Acoustics Scopus Tuned Membrane Bass Trap takes low end control to new level with maximum targeted absorption using a membrane design with an air tight chamber. Think of them like a drum in reverse. When you strike a drum, it makes a sound based on the mass of the head and the size and depth of the drum body. In the Scopus Tuned Membrane Bass Trap, the sound strikes the ‘head’ and causes the membrane to move, absorbing the energy based on the mass of the membrane and the depth of the sealed cavity.

Unlike a Helmholtz resonator which has a narrow range of absorption, the Scopus Tuned Membrane Bass Trap has a broad absorption frequency range from 35Hz to 125Hz. Center frequencies are 40Hz, 70Hz, and 100Hz. It is a perfect addition to rooms that already have broadband control, but still require targeted control without absorbing above 125Hz.

GIK Acoustics also offers the option to build the Scopus Tuned Membrane Bass Trap to target whatever center frequency is required for your needs (please email or call for pricing). For professional, targeted bass control, look no further than the GIK Acoustics Scopus Tuned Membrane Trap series.

Incorporate diffusion in your Tuned Bass Trap with Impression Series or Alpha Series plates.

The addition of an Impression or Alpha Series plate helps diffuse/scatter high frequencies vs a direct reflection off the unit, plus it adds visual impact. The plate will not interfere with low end absorption at the desired frequency.

Plates available in 5 beautiful patterns:

In three different plate finishes: beech wood veneer, white rigid vinyl, black rigid vinyl


Plates available in three scattering options:

  • One-Dimensional – The 1D option uses a mathematical sequence in a column that extends the length of the panel. The vertical slats of the 1D allow sound energy to be scattered in a horizontal plane.
  • Two-Dimensional – The 2D options use a sequence of columns and rows with variable spacing that provides horizontal and vertical scattering of sound.
    • 2D (a) has a pattern of dots and dashes
    • 2D (b) has a pattern of dashes

In three different plate finishes: beech wood veneer, white rigid vinyl, black rigid vinyl


  • 100% pressure based absorption
  • Professionally designed and manufactured
  • Dimensions: 60cm x 60cm x 25cm for flexible mounting
  • Weight: 14.5 kg
  • Target Frequency Range: 30 Hz – 60 Hz
  • Easy to hang or stackable
  • Lab tested
  • Narrow, targeted absorption range (< 1 octave)
  • Custom tunings available
  • You can choose to add diffusion to your Scopus Trap by selecting plates from either the Alpha Series (3 patterns available) or Impression Series (5 patterns available). Plates come in three finishes: beech wood veneer, white acrylic, or black acrylic.
  •  employs ECOSE® technology absorption material.

Certified lab tests have proven that the GIK Acoustics Scopus Tuned Membrane Bass Trap provides better sound quality than any other traps on the market.

There's a difference between a GIK Acoustics product and all others on the market.  We separate ourselves from other acoustic treatment manufacturers in 6 primary areas.


GIK Acoustics Bright White and Off White sqGIK 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. 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.


RAL Absorption ComparisonDollar 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.

Bass Traps & Low FrequenciesWhen it comes to improving the sound quality in a room, many find the science to be overwhelming and the task of DIY'ing acoustic treatments to be daunting. As part of our commitment to our customers, GIK Acoustics provides Educational Articles and Videos to demystify room acoustics. It's long been our goal to help customers truly understand how sound behaves in a space and the importance and benefits of proper room treatment.


GIK FlexRange Technology LogoOver 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, we introduced FlexRange Technology - our unique, patent pending system for providing the best in bass trapping and low end absorption.
