Auralex ProPanels are high-quality, fabric-covered acoustic absorptive panels designed to reduce unwanted room reflections, slap and flutter echoes and provide a more pleasing and accurate listening environment. Auralex ProPanels have a fiberglass core with chemically-hardened edges and are available in a wide variety of fabric colors to appeal to the most discriminating user. 

All Auralex ProPanels meet the Class A Fire Rating per ASTM E-84, making them the perfect choice for use in areas with strict fire codes. Standard wall mounting hardware is included with all panels for easy installation. Auralex Application Specialists are always available to assist you with any questions you may have regarding the specification, selection, or implementation of any ProPanel product.

Auralex M224 ProPanels Corner Traps are 2" thick, 2'x4' fabric-wrapped fiberglass bass traps custom-made to fit smoothly within a standard 90° corner. With reverse-mitered sides, they are an ideal corner treatment solution when increased low-frequency absorption is needed. 

Use M224 ProPanels in combination with B224 or S224 ProPanels for a complete room treatment solution. For additional low-frequency absorption performance, pair the M224 with our DST-LENRD Studiofoam Bass Traps.

M224 ProPanels are sold individually and are available in 9 fabric colors to match any decor. Mounting hardware is included.
