With Precision Sound Products ports, you are able to get the most out of your enclosures. The flared ends lead to cleaner sound and less distortion with no turbulence at the entrance or exit of the port. PSP ports are manufactured from high quality ABS plastics utilizing injection and extruded molding for tight tolerances and guaranteed quality.
The Precision Ports can be mounted in nearly any enclosure as long as there is 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, and with 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 glue or screw it in place.
PSP ports are available in 2”, 3”, 4”, and 6” sizes, and can be made as short as 4” long (on the 2” models) or 5” long (on the 3”, 4”, and 6” models), and as long as you need them using extra tube lengths and connecting rings.
