How come the second port piece is labeled 1'8", but you listed it as 18"?

I don't think the first port piece is labeled right in that picture either? If the port and front piece are 15 1/4", then the port width along the back would only be 4.25".

I don't mean to critique your design, but if the guy is going to build the box according to your design and listed measurements, everything should be right.

Ack. Thanks for noticing that. I was pretty drunk and bored when I made it so my math was a bit off.

I hate converting decimal inches into foot inches... I will not design boxes while intoxicated again //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I apologize for any confusion!

You should be able to figure it out your self.. He gave you all the port dimensions.. and he did do it for free //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

If I go the route of a sealed enclosure that requires 1 cubic ft per sub, I can't just build a box that is 1cubic ft inside because I have to take into consideration the sub and the space that takes up, correct??

 

[miker 5,000+ posts]

What size are those subs?

12"s take up approx .07c ft each. so .14 for two.. So it's not a huge concern..
