I just bought a alpint type X 12 and was wondering what type of box I should put it in and what deminsioins.

 

Good lord man! Your avitars jugs are crazy! she's gonna have back problems.....uh....what was the question again???

 

 

sealed box volume: 0.65-1.25 cubic feet
ported box volume: 1.0-2.0 cubic feet

the smaller the box, the tighter the base will sound. Larger box will give you more boom. Sealed box will give better sound quality. ported box for more SPL (louder).

 

Blackwards pretty much sums it up. It all depends on how you want your car to sound. You want the car in the next lane to feel your bass at a stop light?-go with a ported box that is made EXACTLY to spec. Tight bass then go with sealed.

Whatever you do, get the right dimension for the box. It bugs me to see a good sub in a terrible box. I just cringe on the thought..

 

thanks fellas i appreciate the help i want the car next to me to feel the bass.

 

yeah man, in addition, make sure u get a solid amp to power that sucker. I've heard they are pretty power hungry

 

The bigger the box, the "quicker" the bass should be. The smaller the box, the more boomy it is and peakier .

 

really? is this for sealed or ported. If for sealed, i always thought it was the other way around. can u explain more?

 

yea....1000RMS....and 3000Peak Power.....its pretty power hungry

 

This is for sealed enclosure.

A smaller sealed box means low end extention rolls of earlier, but at the same time the top end increases in both magnitude and extention.

That "tight" sound you hear is actually midbass, not subbass. With a boost on the top end like that, your sub will "sound" quicker, but it's actually midbass that is being played. A larger box increases low end, but top end extention rolls off earlier. A larger box offers the following:

Pros:
- quicker transient response
- increase total system efficiency
- low end extention

Cons:
- space
- less mechanical power handling
- top end extention


Then again, if you build a box that rolls off around 70-80hz then you're good to go. Otherwise, your mids should be the one playing midbass, not your subwoofer.

Cross any subwoofer at 60hz. Even the "tightest" sub will not sound so tight anymore because midbass is greatly reduced. Bass is actually slow sounding relative to midbass. Kick drums sounds quicker than guitar bass mainly because kick drums are in the midbass and lower midrange region.

If larger boxes implies boomier bass, then no one would go with a larger box simply because there would be no benefit. That and also no one would run infinite baffle setup (top end is almost nonexistant, but transient response is ggrreeaatt )

 

Thanks for the explanation ! Now how would ported boxes fare in comparison?

 

has anyone bought from www.caraudiodeals.com ? they seem too cheap, boxes for 25 bucks a pop o_O

 

Buying a pre-fab box for the type X is like washing your new TL with Sunlight dish soap - its just wrong. Custom designed may set you back $150-300 but it is all worth it in the end.

In my opinion, ported is the best set-up for deep bass and punishing SPL. Also, you need less power to make the thing move.

 

yes ported is the best for boomy bass. Don't buy a pre-fab box unless it says its made SPECIFICALLY for the type X, otherwise find a local audio shop to build you one.
