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 two-frame 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 improves lower frequency absorption – up to 50% more low end (below 60Hz) – while retaining 75% more high end (from 400Hz and above). 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 $15 per panel for Range Limiter option.

“The 244 Bass Traps I got from you guys with the range limiter really helped mellow out a 90hz peak I had. Awesome work with that range limiter design! Outside of first reflection points and corner traps I don’t think I’ve ever had a bass trap that made such a profound effect while taking up such little wall real estate.”
