Bass traps are low-frequency acoustic absorbers; they are considered one of the most effective solutions for softening the effects of resonant modes at a low frequency, the existence of which is often associated with the presence of a "boom effect" (low-frequency accumulation) in the room. The bass traps are easy to install and you will instantly notice a dramatic improvement in your room's low-end response, with better-controlled, better-defined and deeper bass sounds.
