After broadband control is applied and overall decay times are mostly in order, problems can still remain in the lower frequencies. The Scopus Tuned Membrane Bass Trap was specially designed for this need. It can be mounted directly in the corner to help with low end decay or mounted/stacked in “hot spots” to tame nulls and peaks.

Typical broadband options require a great deal of thickness to reach very low frequencies often to the point of being impractical and can also over-damp the higher frequencies. Other bonded membrane absorbers do not have the high frequency issue but are still relatively broad in nature and usually absorb up to 1 kHz. 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. Scopus Tuned Membrane Bass Traps work in the desired range only, leaving your mid- and high-end frequencies intact instead of deadening a room.


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 acoustic panel by hand. Unlike other companies who use inexpensive materials, GIK Acoustics crafts acoustic panels and bass traps 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 acoustic panels and bass traps, we offer an array of fine fabrics - from our standard 9 options to the full line of Guilford of Maine acoustic 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.
