Auralex LENRD Acoustic Absorption Bass Traps, Charcoal Gray (8-count)
LENRD stands for Low-End Node Reduction Device. As you may know, a resonance bump in a room's frequency response is called a room node. Now, thanks to LENRD Bass Traps, you can achieve the low frequency sound control other companies can't give you!    Bass traps substantial enough to control nodes have always been expensive to buy or intricate and time-consuming to build, but not anymore! LENRD Bass Traps are extremely effective at smoothing out low frequency room nodes at a price that anybody-and I do mean anybody-can afford! Ask your local Auralex dealer about our MegaLENRD. Twice the width and twice the length of a normal LENRD!
