The LENRD in these Auralex Acoustic panels stands for Low-end Node Reduction Device - and they're meant to spearhead room nodes, or resonance bumps in particular room frequencies. Using LENRD panels, you can experience much more accurate low-frequency reproduction, with an ultra-simple installation. The Auralex LENRD panels fit comfortably in your room's corners and attach to the wall easily. \n
