View Full Version : Treo SSi 12" I want to build slot vented enclosure need help!

06-30-2007, 02:29 AM
OK so im getting a Treo Engineering SSi 12.44. After seeing what my 15" SSI does with 400rms in a sealed I want to make a slot vented for this 12". I think im skilled enough to make the box....and i believe I have all the specs needed

but I don't know how to tune to im guessing 25.XX HZ it calls for if im reading correctly....so if someone could either give me a quick how 2 on how to work around that frequency to get the dimensions i need

like this i picked up from the sticky

1.25 @ 32

that's of course 1.25^3FT at 32Hz right?
btw unless it says it in the specs... I'm not even sure what it recommends for X^3ft for a ported/vented enclosure so if someone has made one for a treo please help me out here haha

If some can do that for me...id really appreciate it but id rather learn...i've always built sealed because its fairly easy....but again I don't know where to even start with making a slot vented enclosure tuned to a certain frequency... any input like formulas needed or start dimensions is welcome, no criticism please!

hey, i have a treo ssi 12, i had ionsql design me a ported box, and with about 500 watts this thing pounds i have mine 1.75 cubic tuned to 28 hz, the lows are loud i had a 4 inch aeroport and the sub inverted, because it looks nice :) treo's are great, cant wait to build a box for the 15" ssi i have

specs for the ssi 12:
1.1 cubic sealed
1.75 cu ft net, 16 sq in vent, 16.5" long port tuning 28 Hz
thats straight from the specs sheet

so what your saying is... after driver displacement i need 1.75 cu ft...and make a 4 inch hole by 16.5 inches long.....where in the box and also im going to be running 800rms and normal (back inside the box) that change anything? i mean isnt a slot vented better?

im figuring out some things after reading the post by BASSOUTLAW on the sealed vs ported sticky......heres what im looking for

A slot vented enclosure for Treo 12.44
Tuned to 30HZ
2^3ft of volume before driver displacement

any dimensions would be awesome as im just starting to work with "Sketchups" to design a layout before i build

the funny thing about my treo ssi is that it was almost as loud as a eclipse titianium 15 i m not sure how loud those are but my friend had a way bigger amp than i did shows how good zapco makes there amps and how treo and hold there ground.

ok soo i was up all night "trying" to understand tuning and all that good **** haha and here's what i came up with for the treo 12...i sketched up 2 possible enclosures. let me know if im right wrong or somewhere close to where i should be haha

First Box Tuned to 35 Hz in a 1.877ft^3


Vent: 1.5x7x9

Second is tuned to 28Hz with 1.765ft^3

Top L:9
Bottom L:14

3inch DIA
11.6inches deep

tuned to high i'd go 32-33hz with that volume

06-30-2007, 08:05 AM
for the slotted? so tune the vent to 31...so im guessing i'm doing the right thing here with these measurements and all? haha

06-30-2007, 08:17 AM
ok i re-adjusted...is this better at 31hz?


06-30-2007, 08:18 AM
does vent location matter, if so where is best to place it...where i have it?

bump so i can stop looking at my thread haha. can someone check over the last diagram make sure things are "copesthetic" haha like i said its 31hz at 1.877ft^3.
