Do I need 45's in my box?

[boomzilla 10+ year member]

I noticed in my slot port on the new box I'm building that in the corner, there's a little more length than the normal 3'' across the rest of the port is. I'd say maybe an inch and a half. Is it ok to put a 45 degree corner in there to make it 3'' across the the rest of my port wall? Or will I have to put 45's in all corners to make it effective enough?

Would... put the 45 in the corner of the port, or in all corners of the box?

Typically a 45 @ the port unless your into heavy competing

put the 45 in the port to keep port width the same. i put 45's in all the corners to add structural strength to the corners.

Ok, I figured just one in the port would be good for the airflow, as my last box I could't figure out where the port noise was coming from, I had rounded all the edges, but that corner screwed me over somehow. Hopefully this box will sound good, and look good too. Thanks for your help!

Table saw or circular saw and tilt the blade 45 degrees

And yea, I would use 45 degree inserts as well in ports

Kool, I was hoping just one in the port would help with the airflow.

My friend had a bunch of scrap mdf laying around and I got it for free, so I couldn't pass that up. I wish I had a camera, I'm doing some resin and fiberglass on the inside, and am going to resin the entire outside for waterproofing and then it'll get some carpet.

No, it's not necessary.
