## Customer Reviews

### ⭐⭐⭐⭐⭐ Sounds good and its Cheap
*by D***R on July 14, 2008*

General infoI used this port to create a home theater sub using the Dayton MKIII 15" woofer. For this installation I have the port mounted in the back with the sub facing forward. I can easily say that I cannot hear any port noise. My subwoofer response is quite low, dynamic and smooth. Even at high volume levels I dont hear a hint of the port.InstallationThe product was quite easy to install. 1st cut the port to desired length, 2nd glue together using a strong adhesive ( i used krazy glue) 3rd position then cut out a hole in your sub box for the smaller end of the port, 4th mount using 4 screws ( these are not included).I would recommend this port based on its efficiency, low cost, and ease of installation.

### ⭐⭐⭐⭐⭐ The Best Commercial Round Port Available
*by M***W on May 10, 2012*

The port is of very high quality. Fit and finish are great. It even comes with a sheet that tells you how to calculate the length to which you should cut the middle tube. The only thing I could find wrong was that the seams inside the port didn't match up perfectly. I would suggest mocking the tube up and sanding down any interior ridges before gluing it together. Sealing the mounting surface with silicone isn't a bad idea either. I used the 4" port in a 2.32 cu. ft. box tuned to 32Hz. My 12" 250 watt MTX subwoofer moves a lot of air and the port is dead silent. Not a bit chuffing can heard. Worth every penny.

### ⭐⭐⭐⭐⭐ Great port
*by D***. on September 18, 2025*

Used this to tune a ported sub box for my 12” P3 punch rocksford sub and it hits low so well, reliably, and with only 400 watts rms. My sub hits harder than two twelves on a 1500 watt amp🤣🤣🤣
