Truck Subwoofer,

[crazycody1993]

So i'm going to build a sub box for my dads truck, but a center console. I was coming here to get some advice on what to do with it, i would like to try and make it a solid low playing box, but i'm not sure how to design a ported box, unless sealed is the better scenario for this sub, unfortunately is a pretty new brand, that doesnt hardly release a lot of information on their stuff. I got these 2 10s for free, and decided to put them to use.

but here are the parameters provided
Fs 28
Qts .75
Qms 3.4
VAS 39 Liters
Xmax .3 inches
Re 2
Pe 1500
Q @ Fs .96 ?usable parameter?
Sens 82 Db

and i have 2, and im going to build a center console in a 95 ford Crewcab, so i have quite a bit of room for a box, any help would be really appreciated

Thanks,
Cody

Sealed or ib are the way to go for those. Low xmax though.

[crazycody1993]

what is ib? and does low xmax make a big issue?

[revboden]

IB = infinite baffle

go sealed ~2ft^3 total for both drivers, i'm guessing here.

there is no way that drivers Pe is 1500. more likely ~80 those parameters are very suspect. you'll have to go old-school and experiment.

unfortunately thats the only option i cant fulfill. he has done walk through's himself, but its kinda our last work vehicle, and the bed will be used, and i highly doubt the 1500 as well, i've been enough around stereos to weed out fantasy from facts. do you think my lower end output will be sufficient in a sealed box? i know with tuning a ported box you can squeeze Db out of it at certain frequencies, and if that requires too big a box, i could do it isobaric to reduce box volume

What is the actual size of the space(centre console) ,perhaps a tapped horn could fit in there?

[crazycody1993]

well does anyone by chance know the size of the front middle seat in a '95 F-350? i will go measure tonight, but if by chance anyone knows and can supply us the info between now and then that would be excellent

I remember JL Audio putting out sealed boxes for the larger trucks that looked like arm rests in the center of a bench seat. The woofer fired down with decent results. Any room for 10"ers in your kick panel area?

[crazycody1993]

Unfortunately not, its a 5 spd, and no room whatsoever on the drivers side in the kick panel

Hi,

With such a high Qts, I'd consider sealed. A ported box (even isobrarik) would end up too big, and getting a flat response would be very difficult.

With regards to the limited Xmax, that'll just limit how loud it can go before distortion comes in. Kinda - it's complicated, but running the drivers past Xmax isn't considered a good idea if sound quality is on the menu.

I'd go for a box as big as possible, make sure it's well braced, then consider adding stuffing (I believe it's polyfill over at your side of the pond).
