My SSA ICON 15 Buck Box Build

So I finally finished (mostly) the box for my SSA ICON 15 that @Buck designed. I just need some carpet. I had one hiccup with the cup terminal. I set my router guide on 3 5/8” instead of 2 5/8” so I had to Jerry rig a scrap piece of wood over it. Pissed me off, but it’s not the end of the world...

Look at the size of that box, it's actually 3.75 cubes @ 28 hz. Now just look at the proportions of that box vs that skar box.

I bet it's 3.8 cubes before port and sub displacement. I bet it's like 3 cubes net or something. Idk wtf is up with the polyfill.

I'm thinking he's wired to four ohm as well. Bad box, or not, that sub should still be making some pretty good noise.

I don't think that box is 3.8xx whatever cubes after sub and port displacement. Big red flag is putting polyfill in a box. Good boxes don't need polyfill, for car audio subwoofer. It does have a proper application, but show me one competitor that runs polyfill in their box.

If you want OP, measure the top depth, bottom depth, width and height of that enclosure, and well as the port height and width.

Look at the Icon 15 box I did, and look at the size difference. Let me see if I can find it.

i can verify the box matches their listed dimensions if that helps.

i'll check it out

it is possible the sub is conspiring against me and not wired at 1 ohm.
the stock terminal on the box is wack

The first thing you should check is what ohm that you are feeding the amp? Is the amp one ohm stable?

yeah it is. i was going to check the sub wiring again tomorrow. is there a way to verify this with a multimeter while im at it?

see my post in that thread.

i lack tools in order to construct a box like that unfortunately

once you put it into perspective my box is lacking

I'm just showing you the box, the size of a proper 15 box. I didn't see listed dimensions on their site.

His box is lacking, but should be making more noise than the 10" that he had.

the specs listed Width: 22.875", Depth 1 (bottom): 23.25", Depth 2 (top): 19.625", height: 19.75"

if we're talking about conspiracies here, i cranked up the bass boost and it was thumping way harder than the 15.
then she died. never again

i was thinking of drilling some holes to get some 8 gauge wire in the box. too many conspiracies here.

Wouldn't 4 cubes net after displacements work for what he has? Tuned to 32-34hz.

sounds like it'd be thumpin. i second this gentlemen. never seen such a monstracity of a box

the specs listed Width: 22.875", Depth 1 (bottom): 23.25", Depth 2 (top): 19.625", height: 19.75"

roughly 4.5 cubes internal without displacements. The sides are inset too though, idk by how much. A 4 cube box tuned to ~32 hz should have bigger than a .5 cube port. I just did some rough math on my phone

That’s not gonna help. You definitely need an alt at that level of power. The box isn’t the best I bet but it still should still be alright. You might check and see if the box is falling apart too, like if any of the pieces are separating.

 

[Buck]

That’s port is gonna be 18.25 tall if it’s 3/4 mdf. If it’s 2 inches wide, that’s 36.5 in^2 of port area, which would be less than 10 in^2 per cube if there actually is 3.8xx cubes.

Are you sure about your sub wiring. A subwoofer that just buzzes could be wired out of phase.

That's a good point, he could have the polarity inversed on one of the coils.

 

[minicorndog]

thanks for all the help guys, got to go out of town for the weekend. next business day i should have some evidence to report.

reporting back next week

hoping it's just the chinsy wiring. the wiring in the box coupled with whatever shop i took it to. who knows

ive looked up some high output alts to no avail. my goal now is to build my system around supporting a 3k amp
i'll keep an eye out, and i have an eye out on a specific deer when the time comes

bobby how much thump you get out of that thing? hit the dm's.
love the AB and how some of their subs got the ribbed surround
