Check this box...

[DOOM_NX 10+ year member]

I am trying to make a box for an MTX T5515-44 by using Bass Box 6 Pro and Sketchup. I kinda modified the port slot (ofc I added the volume that 3 of 4 port sides were occupying in Bass Box). Is this ok? Will this port work?

OH GOD!

THE METRIC SYSTEM!@

MY EYEESSS!!!!!

p.s. 30mm is wayy too small. They'll probably be a lot of port noise. Try to get a 60mm opening instead.

lol ok i can change the metric system

I could get a 60mm opening but I'd have to make the port longer... how? //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Fail

And I didn't expect it to be OK, it's the first box I design

So how do I make the port longer and still fit it into these dimensions? Or I should go for a round port?

Edit: Still, WinISD gives port mach of 0.05...

Any idea how I build an L-shaped port in a sloped box? Bass Box 6 Pro doesn't seem to have any option for this...

22sq in. of port is way small.

22sq in. of port is way small.

x2, shoot for 12-15 per cube

You mean the last one has a small port? I'm not sure i can build something that has an L-shaped port if everything else is small...
