Equalize airflow pressure within speaker chambers Our POREX® porous flow modulators provide precise airflow control between speaker chambers and to the exterior of the unit, thereby reducing air pulses caused by speaker movement. Allowing a freestanding speaker system to breathe freely during temperature fluctuations, our flow modulators equalize pressure within the unit. Designed for precise airflow control, our flow modulators: Protect sensitive electronic and acoustic components–POREX® porous materials repel dust, water, sweat, oils and other liquids from entering the enclosure. Can be custom developed in three-dimensional shapes for increased design flexibility. request sample ask an engineer

High-performing acoustics vents for superior sound quality Our high-performance POREX® Virtek™ IP-rated PTFE vents are designed to have low acoustic loss while providing pressure equalization and a barrier from dust, water, sweat and other contaminants. Designed for IP67 mobile electronic applications, our acoustics vents: Protect against contaminants–POREX Virtek™ materials repel dust, water, sweat, oils and other liquids from entering the enclosure. Assemble easily–Sintered structure allows material to be handled and welded without cumbersome assembly instructions. Maintain performance–POREX Virtek™ PTFE materials maintain performance through assembly process and resist degradation from handling. request sample ask an engineer
