Second look

[Julian 641]

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

[bassahaulic 155]

I like it! :-)

[Julian 641]

160 in^2 of port

[Duran 387]

Gorgeous.

[Julian 641]

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

[bassahaulic 155]

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...

[stevemead08 752]

thought you had two?

[Julian 641]

thought you had two?

One for winter build, two for spring build lol.

[stevemead08 752]

Yawn!

[Julian 641]

Yawn!

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

[Kanaworm$ 292]

Looks good man!

[jonbearsmt 919]

wait... thought you were skar.

[stevemead08 752]

Just fuckin with ya. Do your thing bro

[onebadmonte 235]

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

[Julian 641]

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

[Dangrebel 89]

Shits weak!!! Jkjk lol

[Shogen 325]

yummm.. Woofer displacement???

[Julian 641]

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!

[Ohjay 116]

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.
