I've got a pair of 12'' Audiobahn (AW1251T)'s and im looking into making a fairly simple sealed enclosure. The sub is labeled as 1.00 - 2.00 cubic feet of volume per enclosure. so if i want to put both subs into one enclosure would finding the volume be as simple as multiplying the volume of one sub by two (hence the volume would be 2.00 - 4.00 cubic feet) or are there other things i need to take into account.

also i was thinking of getting a box off of ebay. has anyone tried this and do you recomend it or think its a bad idea. Because my subs are audiobahn's and the back have that cool looking chrome flames i wanted to try mounting them upside down. Are their any advantages or disadvantages to mounting them this way and are their any boxes that are specifically made for this type of setup.

These are some of the boxes i was considering

^ those aren't sealed...from what i understand, the bass will be a lot cleaner if you point the subs down. i had a box in my chevy truck with the sub down, and everyone that heard it complimented it. i would call a stereo shop and ask them for sure.

my recommendation... don't buy either of those 2 boxes. they're bandpass, not sealed. personally, i'd say make your own box... probably about 2-3 cubic feet sealed. or, get something like one of these:

If you want an idea for a box that is very simple to make and also pretty cheap, go plexi-glass. Get some big sheets of 0.5 inch thick plexi-glass and craft your own box. They make UV reactive plexi-glass now, so when you are making the box just put a little UV light in there and the whole box will glow real nice. (I got this idea from clear acrylic computer cases) Just use some clear silicon so seal the box up after drilling the holes and using screws to hold some of the edges together. Don't over tighten the screws, because the plexi-glass could crack if you torque them down way too much. (don't worry, when the bass hits the box will be able to withstand it if you make it properly. A hobby shop or hardware store will have details about how to hold it together properly. I was talking to my friend who works at a lumber/home projects store.)
Below is what UV reactive plexi-glass looks like when lit up.
Or you could just get standard plexi-glass and throw your favorite color neons in there.

is sealed really that noticeably better than bandpass. because i figured with two 400 rms 12'' subs i would have sufficent bass and i should maybe consider looks. How noticeable is the difference between bandpass and sealed

^and does anyone know the answer to my first question

kaput16

basically im interested in mounting my subs upside down. I would try it on a home made sealed box however im nervous that it will be to top heavy and tip over or something. does anyone have any suggestions or pics on how to mount them upside down

kaput16

Bump. can anyone help my with this cause i need to know soon. im gonna be doing this either tonight or tomorrow so i need input asap

kaput16

Bump Bumpity Bump Bump Bump. Anyone. Anyone At All. I Need To Know Soon God Damnit.

allright, first off forget the bandpass enclosures. What kind of music do you listen to? What kind of amp do you have?

kaput16

I listen to Rap, Hip-Hop and techno. I have a JBL BP 300.1

Ok you do not have a tremendous amount of power so your best bet is gonna be ported enclosure toned to around 45hz . This will give you the most output for the given amount of power.
Crutchfield sells the box that would work great for that! the model is QLH-1.7512DE by qlogic. the ports would be cut to length by using the theil small parameters the subs are provided with in a formula to figure the precise tune to frequency.

one more question. for my subwoofer it says the best performance will come from a box with an internal volume of between 1 - 2 square feet cubic feet. that is equal to 1728 - 13824 cubic inches of space. theres a pretty wide gap between these two numbers. would it be best to go to the average of these two numbers being 7776 cubic inches. or is the most space possible the best way to go

the volume for cubic inches is just 12*12*12*x = volume in cubic inches where x is just the number of cubic feet you want. your range for one sub will be between 1728 and 3456 cubic inches

hope that helps

kaput16

^ yeah i put in the wrong number sorry but thanx for the help. so would i be better going with the average of those two numbers or is it better to choose the largest or smallest cubic volume
