The Monster Bass Trap with FlexRange Technology is our most effective panel, raising the bar for bass traps. Measuring in at a whopping 7.5” thick, the design of the Monster 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.

With the Monster Bass Trap with FlexRange Technology, low end becomes clearer making it easier mix. No more guessing on bass levels during mix down. No more hassles trying to clean up nasty nulls and spikes that are common in all rooms. With new certified lab tests, the Monster Bass Trap with FlexRange Technology has a rating of 24 Sabins per unit – 50% more effective than our 244 Bass Trap with FlexRange Technology. There is no other product on the market that even comes close.

When combined with our proprietary RANGE LIMITER membrane system, the Monster Bass Trap with FlexRange Technology absorbs up to 50% more low end (below 60Hz) and retains 75% more high end (from 400Hz and above) versus the broadband FULL RANGE option.

While many commercially available products are simple fabric-wrapped panels, the Monster Bass Trap with FlexRange Technology is precision engineered and manufactured to exacting standards. We begin with a two-frame system that allows sound to travel behind the panel for greater low-frequency absorption. GIK Acoustics uses high-quality fabrics as our standard options as opposed to cheap burlap or microsuede. Our materials are Greensafe which means GIK products are easy on air quality for your room, the environment, and your budget.

The Monster 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) or as a cloud on the ceiling.

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.

After adding GIK Acoustics 242 Acoustic Panel to your cart, you can then select the Scatter Plate and have them built into your 242 Acoustics Panel for only $49.00 per panel.


Instead of mounting the panel on the wall, we offer our Boom Stand Brackets. Installing these brackets on the panel allows it to attach to any boom stand turning your 242 Acoustic Panel into a gobo or a portable vocal booth. For only $12 each you can add increased flexibility to our acoustic panels. (Boom stand not included.) Click here to add boom stand brackets to your order.


Another alternative that adds flexibility to our acoustic products are our Custom Metal Stands. Our metal stands are modern, contemporary and powder coated for greater durability. Complete your GIK Acoustics order with our free standing custom metal stands. Looks great and provides flexibility! Click here to add custom metal stands to your order.


Hanging panels from the ceiling can be difficult, yet it is one of the most important areas of your room to treat. GIK Acoustics makes it easy and low cost by offering this simple bracket mount that hangs with a couple of toggle bolts and screws while also providing a 4" air gap to further absorption. Click here to add cloud mounting brackets to your order.
