 Adjustable Loudspeaker Ports

   These adjustable Loudspeaker Ports / Vents are available in three vent diameters. They consist of two close fitting PVC tubes which slide to produce ports of varying lengths between (110 and 280)mm depending upon the port diameter. With three choices of port diameter, (35, 51, 61)mm these vents can cover a wide range of cabinet sizes from small to large. The tubes can be locked to a specific length with a small self tapping screw. Ideal for easy experimentation / box tuning.
