3 15s box help...

Recommended Posts

So trying to figure out how to make a box and am I doing this right? Gave up on the aeroports...

3 15s on ns1 amp...

Debating on inverting all 3 subs or maybe just 2...not sure what would look good...

Re calculator is no good. Use Torres or even CT sounds calculator is pretty spot on with Torres.

Been told to stay around 9cuft (3cuft each) with the Contralto 15s and nothing is working out 🤣

 

Gotten so frustrated with it that just gave up...

 

 

And no computer now so can't download anything to help me figure out what I'm doing 

 

*shrug*

 

Also don't know if should go with 2 8in aeroports like originally planned or just slot port it.

 

This is my 2nd attempt at a box, first one didn't work out...

I can get you some good numbers for a box. I'll look up the Crescendo specs and post numbers shortly. I prefer slot port myself. 

Are you limited to 18" high?

Also... 42 wide will be tight for a slot port design. Probably want to go aero port if you're limited to that width. I also can't find woofer displacement #'s anywhere. Lmk

What 15's require 5ft³ each? Even zv5 and nsv4 15's with over 33mm of xmax only require 4.25 maximum. 5ft³ is too big for 15's.

Specs are 44w, 19.5h, and like to stay around 30d...

 

I've really wanted to do an aeroport box for awhile now but I can't get it to work out right on that app hahaha...beening looking at 2 8in ports...

I do believe 3-3.5cuft per sub is the magic number...

 

Subs will be 2 inverted, one in the box so sub displacement is 0.23...

3 cubes sound pretty small for a 15. Most of the 15s I have used wanted between 4 and 5 cubes. But I'm also a big box guy too, cant stand a too small ported box

 

Fi, psi, DD... all want 3-5 for most of the 15s. I dont run sundown so I dont know.

I talked to Crescendo audio today. They suggested 10ft³ with around 144in² of slot port. Less with aero. I can actually get a design with subs up Port back ( slot Port ran across the bottom).
