sealed boxes

Yes

Yes

but squeak9798, i calculated the same subs that my brother has from the pioneer premier line, EXCEPT his are SVC subs and mine are DVC. now his specs are a little smaller and using the equation that you and Jmac posted, i got a

total of 0.3549 plus sub displacement of 0.0089 = GRAND TOTAL - 0.3549 cu ft.

my total is a little larger at 0.462+0.0089= 0.551.

but my brother numbers seem SO small. have you ever heard of people making a single sub box that small? at the moment he got them in a pre-fab at aroung .8 cu.ft maybe or more per sub. he's running 2. but i told him to go with building a box and that we could use these numbers. i guess if 0.3549 is what it sayd then i cant argue. its just i never seen a box that small. i guess its coz most people here run pre-fab junk. but even reading of the forums, i never came across it. should it sound good in that small a sealed box ?? thx!

part 2 of my questions:

is it even POSSIBLE to make a small sealed box for 0.3549 ?? if so, what kind of dimensions of the interior (WIDTH / DEPTH / HEIGHT) would he need??

Well, unless the T/S parameters are incorrect....yes.

Um, yeah.

12" x 8.75" x 6" = .36cuft

Hope you have a 6.5" driver. That box wont even fit a 8" sub.

Oh and 95Prober,

.5 cubic feet is a pretty small box. Trust me. My ported box for one speaker nets around 3.15 cubic feet. Thats a big box

so it should sound great with that size a small then. i hope so. and no the T/S numbers are correct. i checked many times. i know pioneers arent the greatest and largest in dimension subs but i thought it would have to be bigger. ah well, i better learn to follow the numbers and stop comparing my subs to other subs and boxes

well, you cant compare my subs for a ported box, can you? both are totally different. if i port mine, it should and would be bigger coz of the different modifications you can make towards port and tuning. BUT this is for a sealed. wouldnt squeak's numbers work? look fine to me >12" x 8.75" x 6" = .36cuft

Hey, I was just showing it was possible //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

I was not comparing //content.invisioncic.com/y282845/emoticons/read.gif.ff512c499c00ed3faae9a20f4b088b29.gif I was just pointing out that .5 cubic feet is small. And by stating my 3.15ft^3 box in size comparison, you could see that .5ft^3 is very small.

How do you plan on putting a speaker in a box that is 12x8.5"???

A 12" speaker requires 13.5x13.5, a 10" requires 11.5x11.5, an 8" requires 9.5x9.5 at the minimum.

I think he was just showing you how to make a .36ft^3 box.

also, after just checking with pioneer on their site, they recommned a 0.6 cu.ft. its only NOW i seen it.

BUT, that is only a good recommneded size for the average person to them a rough idea. since i am going with the EXACT specs, would it hurt the sub any going UNDER the 0.6 and making it 0.36 ??

ahh. yeah i understand. but im so confused. i mean, i go out and use the EXACT numbers and i get a result that cant even fit in the size that i get (0.365 cu.ft.)

so, i cant fit it right, i guess i have to go higher to the LEAST / SMALLEST possible

BOX which would be : 11.5 x 11.5 x depth, which i assume 6 inches at least

?????

What is the mounting depth of your speaker???

If it is less than 6" your good. 11.5 x 11.5 x 7.5 with building material of .75" would equal .35ft^3 before speaker displacment.
