The Precision Port 4" Flared Speaker Cabinet Port Tube Kit uses flared ends to reduce turbulence at the port entrance and exit, which can cause unwanted noise and poor sound quality with conventional tubes. The system can produce a gain of up to 3 dB in output and is designed for low distortion and superior overall sound quality.
Create a port up to 17" long. Front screw holes make installation easier, and installation instructions are included. Glue with ABS glue, available at any hardware store.
Dimensions: 7-1/4" outside flare outer diameter, 6-1/4" cutout, and 6-3/16" inside flare outer diameter. Also available in 2", 3", and 6" diameters. Proudly made in the USA.
