What do you think of this 4th order?

[20 hz bass machine Premium Member]

Ive been doing lots of studying and practicing with my enclosure designs recently. I just finished this 4th order for a guy down in Alaska! We met on Instagram and after a lot of back and forth we finally have a completed design.

The box is a 2 to 1 4th order tuned to 55 hz for 4 SKAR EVL 18s. Sealed side volume is roughly 13 cubes and the vented is 26. Port is 17.6"x 36.4"

The guy is going for maximum SPL hence the higher ratio and tuning. Give me you're honest thoughts.

Thanks

Only problem I see has to do with the choice of subs being Skar

Good luck with the build man. People on here have a personal thing against Skar that goes back a long time. I hear the same kind of shitt about American Bass. Don't take it personal.

You're entitled to your opinion. I don't take anything personal. Not everyone is like me though. A lot of people leave the scene after getting shut down online. Its guys like you who are killing the car audio community.

I like how he says, "Help" after he just ripped you on the selection of the subs. You asked for thoughts on the box, not the subs. I have noticed two subjects that trigger pretty much everybody on here, Skar and Down 4 Sound. Gets em' every time.

What's the port area per cube for the ported side? That is pretty high tuning. What's the Frc?
