Why use PSP Flares?A "flared" port is defined as essentially a straight port with one or both ends that "bell out." The curvature provides a smoother environment for the signal path, allowing the bass frequencies to speed up as they exit the box.
This results in more sound pressure and more sound quality at the same time by reducing port noise. Port noise, or "chuffing," is the result of a column of air moving at speed, trying unsuccessfully to integrate smoothly with the surrounding air, which is at rest. What's happening is that the air in the port is getting compressed to the point that once it reaches an area of lower pressure (the outside of the enclosure) it sprays out everywhere, similar to holding the end of a hose slightly closed.
If the speed is low, the air is able to maintain smooth flow and all is well. Above a certain speed, turbulence can occur, which is what we call the "chuffing". Flared ports lower the velocity of the air at the boundary between the port and the outside environment, and so the airstream encounters a larger area of still air and remains smooth.
- Greater Sound Pressure Levels: The PSP Flare can add an average of 3db in output if used correctly.
- Cleaner Sound, Less Distortion: No turbulence at entrance or exit of port.
- Cosmetically Appealing: The mounting flange on the outside flare has been textured to be more appealing to the eye.
- Adaptability: Can be used in any type of ported enclosure as long as you have left a minimum diameter of 5.25" for 2" ports, 6.25" for 3" ports, 7.25" for 4" ports, and 9.25" for 6" ports.
- High Quality ABS: In order to obtain a high quality part we utilize injection and extruded molding processes. This allows PSP to achieve closer tolerances so all parts will fit properly.
- Easy Install: Due to the design of the 3" and 4" Precision Ports you can simply cut your port hole to the same diameter as the flared end of the inside port, drop the assembled port in and either glue or screw it down. No need to use round-over routering and back filling.
- Mounting Hole Variations: The mounting flange on the 3" and 4" outside flare is made with predrilled holes. The 2" and 6" outside flares have recessed drill bit guides on the back of the flange if you want to drill mounting holes. The 2" and 6" also have a ring on the back side of the outside flare to help secure the flare in the enclosure.
