AmmoTenna PSP3 3-Inch Port Kit, Black, 1 Count (Pack of 1)

I love these. They are easy to trim, allowing for frequency tuning to net airspace volume. The port ends are nicley flared, and easily glued together with PVC adhesive forming a strong and rock solid port. Performance is cleanly tune hard hitting bass with minimal air noise. Great product for the money, and a must have for audiophiles.

Installed in my sealed truck box. No distortion. Easy install

It worked and controlled the port noise on a Klipsch 10" subwoofer. A little modification had to be made in order to get it to fit.

The material is a little thin and the pieces don’t fit together as tight as I’d like. I used liquid nails to glue it together and it’s been working great for my 8” sub. Overall happy with it.

So far these are easy to use. I used a miter box to chop these down to size. I used pvc glue to bond all the pieces together. Seems to be a good strong bond so far. The flare is big and at first I drilled a 3” hole for the tube but the ported flare requires the hole to be larger. It’s probably closer to 5” now. I used silicone around the hole so it seats perfectly and drilled them in. They look awesome!!!

Helps my two 6.5" Crossfire subs playing the way I like it!

Package came fast as expected. Product is all there.I just needed the flared end parts. Maybe you guys could sell just the end pieces.. I won't need the middle section on my current box but maybe in a future box.Thanks for the quality product delivered on time!!

Only con is that you can't go back once you cut it but overall works like you expect a port tube to work..
