    Thanks guys! That is helpful for future crazy builds!!

    Thanks Tom! I do have days I think how much I could do in the stations..... Hoping to get my bunk setup done the next two-three weeks.

    Hurry up.
    Hoping to wrap up tomorrow!!

    I could have..... Idk. :p

    Second, I love my TC Sounds sub, but I wish they would do a better design for breathing with that basket.
    Makes it more difficult to get your baffle correct.

    Third, sorry, you're going to have to redo the PVC, one of the pipes is 1/4 inch shorter (just kidding)

    Fourth, you'll probably blow the windows out of that Ranger!
    It took me some time sitting there and playing with the PVC to figure it out. It would be awesome if the windows go.

    Re: Hamster Habitat Sub

    Thanks fellas! The port was definitely a challenge, but I really wanted to use PVC instead of a slot.

    I recalculated everything this morning....

    Gross internal volume = 2.3 cubes
    Ports = .6 cubes
    Driver = ~.08 cubes
    Bracing = negligible

    Net internal volume = 1.6ish cubes.

    The nice thing about the way I built it is that the couplings are on the side of the box and the ports extend out, so I can change the tuning of the box with a max tuning of 34hz. The way I built it tuning should come out around 27-28hz. I was hoping to get the net volume closer to 1.8 but that caused more headaches than necessary with the external ports and I've already used all the space I can for the enclosure itself.

    I should end up with an F3 of 24hz, a +1db peak at 31hz, anechoic. I think the small cab of the Ranger helped boost the sub 40Hz when I had the 13A in there so I should get a bit more reinforcement down there. :D :D

    I'm excited to see how this compares to the 13A.

    Holy Cow!

    That's a lot of port! And the voice coil looks like it was made with Romex! That is some low gauge wire there.
    Curious, what's the box volume minus the ports? You sure needed to get creative to get that much port in there, nice!
