Our take on the Port Tubes

These port tubes feature molded grips that ensure a secure fit in your box cut-out and a rolled front flange which sits flush against the outside of your box. You can trim the ABS plastic to the proper length for your driver and box combination.

BIG difference!

Unknown from Earth on 10/29/2005

I just bought some of these from somewhere else (no offense Crutchfield) and I cut the holes in my box and put them in. I wanted to know how big a difference there was with them, so I took a piece of cardboard and covered the tube's hole with it. The speakers seemed like they made much less bass with the hole covered, and so I took the cardboard out. I tested it again, guess what? It sounds great now! I recommend these...
