## Description

Precision Port 6 inch Flared Port Tube Kit The unique flared-end construction of the Precision Port system enables it to outperform any standard port tube on the market. Conventional tubes suffer from nasty turbulence at the entrance and exit of the port, producing unwanted noise and poor sound quality. The Precision Port system overcomes these problems and as a result can actually produce a gain of up to 3 dB in output! Now you can experience good looks, low distortion, and superior overall sound quality thanks to the Precision Port system. Convenient front screw holes make this tube easier to install than others on the market. Create a port up to 17" long, then glue with ABS glue found at any hardware store. Installation instructions included. Dimensions: 9-1/4" outside and inside flare outer diameter 8-1/4" cutout. Also available in 2", 3", and 4" diameters. Proudly designed in the USA.

Review: great product for building boxes! - this product is amazing! it makes building a box for my single kicker L5 15 easy as pie! i got this mainly because its as easy as building a sealed box, cutting a circle in it and plopping this port inside.. BAM you have a good sounding ported box. i didn't want to go through the hassle of building a slot port which is hard to get it tuned properly, with this tube you just cut it to the right length (instructions included teach you how to do so) and put it in! this allows for a smooth roll off due to the flared ends, and there is no "chuffing" sounds! i couldn't have asked for more. i went from a 2 ft^3 slot ported box tuned to 40 hz, to a 5.5 ft^3 box (aero ported) tuned to 32 hz and the difference was night and day. i feel lows down to 22 hz and my doors and spoiler on my grand-am shake like crazy! i was at a stop light and the school bus pulled up to me while i was bumping, then a few minutes later my cousin got off the bus and said (when we pulled up to the light everyone stood up and was wondering what was shaking the bus, then i realized we were behind you..) Seriously don't waist your time trying to build a slot ported box, this is so much easier it took me a few hours to build my box and my single 15 sounds louder than any dual 12's out there! (not all dual 12's but still it's pretty damn loud lol)
Review: Good product, could use a bit more work. - There needs to be a smaller flare at one end that doesn't interfere with the hole on the box. Sometimes the ports aren't easy to glue and install from the inside. The port came undamaged and fits perfectly together as expected.
