These rack cabinets are designed to be noise and temperature controlled. Anechoic foam and special baffling allows the thermostatically controlled vent fans to run with almost no exterior sound. We can build these cabinets in any size or style. They can also be mobile if desired. Noise and temperature controlled cabinets are designed based on the specifications made by the AV integrator, thermal or acoustical engineering firm. Marshall Furniture does not offer engineering expertise in these fields.
