A resonance bump in a room's frequency response is called a room node. In the past, bass traps that were substantial enough to control nodes have been expensive and time-consuming to build. Auralex has solved that with the LENRD Bass Traps. LENRD stands for Low-End Node Reduction Device, and it is extremely effective at smoothing out low frequency room nodes, while still remaining affordable. It has an NRC of 1.50 for useful bass reduction.
Easy and cost-effective way to control low frequencies without giving up large amounts of cubic space
Fits room corners and wall/ceiling junctures perfectly
NRC of 1.50
