Airflex Port

Less flow noise

A lot of subwoofers and loudspeakers employ the bass reflex principle to enhance bass reproduction. Higher bass levels are produced through an opening in the enclosure by the sound being used additionally in the interior volume. This requires bass reflex tubes precisely matched in terms of length and diameter to ensure that the acoustic pressures add up in an optimum manner. Due to the physical properties, the tubes have a smaller diameter than the bass speakers, meaning that the air flows through at a higher speed. This can cause undesirable flow noise, which impairs the reproduction. Magnat´s Airflex technology provides a remedy for this. Magnat Airflex ports are rounded aerodynamically at both ends. These rounded ends hugely reduce undesirable background noise and, in this way, ensure particularly clean bass reproduction, even at high volumes.
