I'm thinking of going with a 15" Q for these, powered by a Sundown SAZ-1000D

So I've been messing with the RE calculator and think I have come up with a couple of designs. I just want to make sure all the numbers are right on these and see some opinions on which one is better. I like the first one more, sub up port back, does that design output well? How do you make the horizontal and vertical 45's come together smoothly? Also, would the first box fit a 15" BL? I know the second one doesn't have the airspace for a BL which is another reason I like the first one. In case by the time I order I decide to go with a BL (I'm very indecisive)

This is going in a hatchback (2003 Hyundai Tiburon)

Either would work, but why two threads about it.

Agreed, I deleted your other topic.

What are you talking about with the horizontal and vertical 45s?

Sorry for the two threads, I originally thought I had posted in the Gen FI forum but realized today when I couldn't find my thread in here that I accidentally posted it in the SPL / SQ board which the more I looked at was more for crazy design stuff it seemed as opposed to just a regular box.

The 45's I'm talking about is how you have the vertical 90 along the edge from top to bottom, you angle cut a piece to fit in there from top to bottom that forms a 45 degree angle. You also have a 90 along the horizontal edge from left to right. You angle cut a piece to fit in there from left to right that forms a 45 degree angle. Now in the corner where the side and top and bottom all come together, if you have pieces cut to make 45's along the edge, they won't be flush in the corners where everything meets.

Does that explain it or should I bust out the MS Paint lol

You just have to cut the end at a 45 degree angle on each piece where they meet.
