PSP Modular Tuning Ports

Modular Port Tube with Mounting Holes

PSP modular tuning ports with mounting holes. The Modular Port is designed to reduce the amount of air turbulence at the entrance and exit of the tuning port for speaker enclosures. This is achieved by the flaring on the two sides of the tuning port. When the air turbulence is reduced, distortion and port noise are also reduced which gives the enclosure a cleaner sound and greater sound pressure levels. Available in 3 inch x 17 inch and 4 inch x 17 inch.
