box build for 12" mtx 9500 x2

[SMpaintball78 58]

Hello SSA,

i recently picked up 2 12" mtx 9500's in a custom HUGE ported enclosure. i have a ext. cab ford ranger and the box is about 6"'s from my roof. the length of the box is fine, but its WAYYYY to deep. i was wondering on what i should do. i had 1 12" mtx 9500 in the sledgehammer ported box and it sounded AMAZING in my truck. i know alot of people say the sledgehammer boxes are hsit, but for osme reason it sounds really good in my truck. i cant find the sledgehammer boxes anywhere, so i decided to just build my own. iv never built a box befor. i have all of the tools to do it and all the materials in my garage ready to be cut. i have a good amount of knowledge when it comes to box building. i have helped on myany projects, but never on my own. so what do u all think? do i keep looking for the sledgehammer box? or do i build my own????

Thanks

Since you say you already have all the materials needed I would go for building your own.

You did not say if the subs are dual 4 or single 4 ohm, but the recomended box spec apear to be the same on the support site.

Here are the specs for the box they recomend for one: http://www.mtx.com/caraudio/products/subwoofers/TechData_T9512-04.pdf

Got that from here: http://www.mtx.com/caraudio/products/manualsQuickInstall/subs.cfm

Good Luck!

just make a single ported box for both no need for 2 boxes

im going to make 2 single ported boxes and screw them together when im done because im going to use the dimensions off mtx's web site. im going to start cutting in about 10 mins.

I would recomend a single chamber enclosure. I am not a box designer but you should be able to double the air space and double the port width of the recommended enclosure the real ? would be the length that the port should be for the desired tuning.

[SMpaintball78 58]

ya. im just doinf it to mtx's spec's. its much easier and i dont have to worrie about it sounding like shit because i tuned it wrong

[NB50 206]

Looking at MTX's box plans I'm not impressed, its tuned to ~41hz.

[SMpaintball78 58]

well my first box turned out really good. doesnt sound bad either. it is tuned a little high but its all good

[Ohjay 116]

Should slam on high notes and peter out quickly digging deep. There used to be a cat running one of those a while back around here, pretty damn loud for 1 12"

well after school today, i went to my local audio shop and asked if it was possible to extend the port for a lower tune with these box specs and so i did. my total port length is 25" and tuned to about 35.5Hz. it sounds 10X's better! i begin my second box tomarrow!

glad to hear you're happy with the the turn out. I built a custom box for a pair of these a while back that a friend put in his car. They slammed like a mofo... Post up some pics once you've got it all done.

[SMpaintball78 58]

With mainstream products like MTX, Kicker, etc. it's almost guaranteed that you should not follow the recommended specs. 99% of the time they're going to be small boxes with a small port that's tuned too high. Why? Because those kinds of boxes don't take up a lot of room, so you can fit more of their product in a given install.

The 9500's are actually really nice woofers if you're looking for a groundpounder kind of setup. They certainly have a lot of potential...

ya. idk i built my first box to there exact specs. and it was tuned WAY to high. so i extended the port 10 inches to make it tuned to about 35 hz and it sounds 10x's better. why doesnt mtx just tell people to make the port a total of 25inches instead of 15????? it doesnt take up any more room on the outside and it sounds better.

[SMpaintball78 58]

well here are the pic's....

[smashedz28 110]

as long as your happy then you did it right. good job on your first build.

[nigel 148]

looks to me you did a pretty good job from what I can tell. If you're happy with the result then that's all that matters. Have fun with the setup.

[SMpaintball78 58]
