Designing my box for my ZCON 18 this is what I came up with, does this look right to you guys?

I like it! :-)

160 in^2 of port

Gorgeous.

Going to start it this weekend, If I wake up early enough I may pick up some wood today and start the build Saturday.

Its going to be low as hell with such a large port and low tuning.

"Violent" comes to mind going on my 3500 at 1 ohm...

thought you had two?

thought you had two?

One for winter build, two for spring build lol.

Yawn!

Yawn!

YOU don't have snow and Ice and no Garage! lol

Looks good man!

wait... thought you were skar.

Just fuckin with ya. Do your thing bro

Oh my, that is one monster of a box. It's as big as the box my 9515s are in.

Big ole box 160 in^2 of port tuned to 35

Shits weak!!! Jkjk lol

yummm.. Woofer displacement???

ends up around 7.5 feet, bracing with allthread will drop the displacement down a bit.

Your sketch up is not accurate, port is not the same width the whole way and is longer then 29".

Yeah I noticed that I did that on accident!

This thing should be nasty with the power/volume you plan to use. My brother is using a SAZ3k on his 18" Zcon in only 6^3' and it's impressive.

You beat me to it.

I've never used that box calculator before, but the port length dimensions on the calculator don't make sense either.

That's not taking end correction into account which would shorten the physical length of the port.

The values look backwards to me, or is this the way that program works?

Also after woofer and bracing displacement keep in mind that you'll be closer to ~37-38 tuning.

Looks like it'll be awesome once it's finished.
