Dual Fi SP4 18s

[CaddieJapan 10+ year member]

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.

You should try 4 12's.

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?
