In most rooms, the main problem at low frequencies it due to one or more deep nulls or peaks in the range between 40Hz and 200Hz. Bass traps reduce the depth of the nulls and attenuate the booming sounding peaks. The overall response of the room is flatter as a result. Even though your brain intuitively thinks that you lose low end by attenuating it, the room will actually sound tighter and more predictable. It'll also sounds better as you move away from the sweet spot. Just like acoustic panels, broadband bass traps are comprised of a core absorbent material, a frame and a covering. These are called broadband bass traps because they work across the entire low-frequency range. Not just one particular area of those frequencies. The core is made from any absorbent material like Owens Corning 703, Rockwill or reven R19 fiberglass batting as long as it's at least four inches…
