Can I get someone to assist me with an enclosure design for dual SP4 18s. Max dimensions are 27W x 30D x 30H. I'm currently running 2 15s and wanting to go with 18s. Power is a non issue since I'm now using two Crescendo 3.5ks. If this is possible please let me know. Looking to order the subs this week.

Also looking to go subs up, port back.

4 day weekend, so just kind of kicking it around man. Been thinking about going with the 18's like you mentioned man. First and foremost though, just wanting to see if I have the optimal space to do so. If so then I will go for it man.

Well that's like 14 cubes gross, so minus port area, drivers (unless you mount inverted, would look pretty bitchin in the van if you did), and other displacement you have a little over 5 cubes each. Might be tough :/

But check the texts.

I wouldn't do that. You have about 11.67 after six sides with double baffle, you want 12 minimum IMO for those woofers net.

I'm tellin you man, go HDD's. Just talked to Murph and he said 5-8 cubes would be fine.

That was my thought. Looks like the correct box volume for 1.

Are you going to have the subs on the same plane when your max dimension for any side is 30"? How is the box for the 15s you have now?

The 15 box I have now was built by Starr Mtn. I was hoping to go 18's, but if I don't optimal space for the enclosure then I will go with the 15s. Can anyone provide measurements. I know for fact I can only 27 w. I maybe able to squeeze a tad more out the other ways. So I could run the HDD 18s and be fine with what I have?

Bro, this^^

Two 18's are going to require at least 37" on one face. Can't believe I didn't catch that before lol :facepalm:

You're gonna want 4 12's.

How do you fit your 2 15s with no dimension bigger than 30"? different sides of the box?

Current enclosure is 24dx 27wx 30h or close to it.

That box you have now has to be 33-35" wide or so.

You could do it with your max dimensions.
