Overview
Prime7-Fe™ is an attractive, furniture- grade hardwood wall system easily installed to most any architectural surface. Its decorative finishes and profiled design combine to provide single-dimension mid-high frequency diffusion for control of flutter echo, while preserving the natural ambiance of the space. Type – LFA (optional) has rear reliefs engineered to provide additional absorption below the frequency range of the diffuser cut-off frequency. Additionally, Prime7-Fe™ profiles can be installed with a rear air space and with slight separations, along with a glass or polyester fiber back-layer for increased low frequency absorption. This product is a quadratic residue design derived from mathematical number theory sequences for reflection phase grate principles, then precisely manufactured to provide a combination of mid-high frequency diffusion with low frequency absorption; all in one product. Finished profiles are solid core materials to prevent resonances and resist damage. Finishes are factory applied on standard or customer specified wood species.
