Bass Trap

Bass Traps are designed to help control excessive low frequency build-up that cause room modes in studios and listening rooms. Acoustic energy naturally migrates to corners using the walls and ceiling as waveguides. This makes corner-mounting the bass trap the preferred location.
Bass Trap kit consists of two 24″x48″ (61 x 122cm)Wall Panels 2″ (5cm) thick absorption panels along with corner-mount Impalers, sheetrock anchors and screws. Each panel is constructed from high-density 6lb per cubic foot (96 kg/m³) glass wool with resin hardened edges and fully encapsulated with micromesh. The panel is hand wrapped with an acoustically transparent polyester fabric to create sharp, architecturally pleasing lines. Installation is just about as easy as hanging a picture! Once installed, the substantial surface area of the panel combined with the 17″ deep (43cm) air cavity created in behind delivers excellent absorption throughout the audio listening range and extends well down into the low bass region. This helps reduce troublesome room modes and hot spots by attenuating standing waves making it easier to record and produce music with greater confidence.
Bass Trap kit is the perfect add-on to the Prima 8 and 10 room kits or may be incorporated into any room where low frequency control is needed.

Prima corner impalers make it easy to mount the 24” x 48” panels across room corners to form effective bass traps. Like the surface impaling clips, the corner impalers feature sharp tips that penetrate the panel and hold it securely in place.
