Port Tube

Overview

Our take on the Port Tube

Building your own subwoofer enclosure? This port tube features a rolled flange to ensure a clean fit on the outside of your box. The tough ABS plastic tube features markings that make it easy for you to trim the tube to the proper length for your driver and box combination.

They work great, no issues. Fantastic price!

Standard port

Written by: Jon from Tyrone, PA on May 17, 2016

Crutchfield Customer Review (What's this?)

Standard port. Does what you expect. A little noise But if your box is in your trunk you never hear it. Adding a port to a box definitely increases bass output from almost any box. Crutchfield should offer a better selection of ports. Longer ports are often needed with a smaller box. Flared ports eliminate port noise. Neither of these are offered.

Pros: Flanged too easy to install

Cons: Very small amount of port noise.

Nice ports

Why did you buy this?

I listen to heavy metal and rap. As with most people that enjoy these genres, ported boxes sound much better [ Jon  May 04, 2016 ]
