ok that's cool and all...but you DO plan on putting an actual box in there right? just curious...

what a worthless post. being a newbie or member or advanced member does nothing anyways :01nocomment8so: ima get to some number crunching for you now

wat in da wurld do ya meen? crazy foo

lil jon was a fad. he was in style back then, now he's out of style. i like myself some club music personally too, but this, this is bad.

krannyman...the randomness of your avatars never ceases to amaze me lol i can tinker with a design for you, but i *need* to get some homework done asap, so i'm going to tackle that first. someone else may chime in by then, but if not i'll do what i can welcome btw

i believe it's also in the rules that you cant just slow or speed up a song and make it available for download. just fyi

yes....please

Audacity

no production? i might shed a tear if i had an extra 3600 i'd scoop those up so fast. talk about one of a kind well...3 of a kind.

no prob! make sure to let us know how it sounds

is this going into an SUV i assume? i usually like mine as wide as possible, but to keep the depth and height as large as possible to fit it as far as mounting depth go and all, i had to shrink down the width a tad. i got 20" high, 37" wide, and 19" deep. port is 3.5" high, 20" wide, and 20" long. this will get ya 5.45 cubic feet tuned to 34.75 hz. with about 12.6 sq inches of port per cubic foot. with some bracing accounted for.

yeah keep using andy's. much better than the RE one. and you can use aero's in mine but...you just gotta figure out port area yourself lol. but maybe i can add that in

lol whoops! reading > me lol. lemme refigure

for box volume, the internal dimensions are 28.5 x 22.5 x 15.5. that's effective net volume after wood displacement. based on you using .75" wood. this gets you 5.7 cubic feet. now for the port, you have 3 x 20, but you need to account for wood also. so to figure actual port displacement, you need to do 21.5 * 3.75 * 19.65. (add in half of the port height for end correction) this gets you .92 cubic feet of displacement. and say ~ .2 for the sub. so now you have 5.7 - .9 - .2 which will get you ~4.6 cubic feet of net volume, not accounting for bracing

20" high, 40" wide, and 18.5" deep, with a port that's 4" high by 20" wide and 24" deep. this will yield 5.58 cubic feet of net volume, tuned to 34 hz. that's about 14 sq inches of port per cubic foot. or if you wanted a lil less port area (to help the lows), you could do: 20" high, 40" wide, and 17.5" deep with a port that's 3.5" high by 20" wide and 20" deep. this will give you 5.49 cubic feet net, tuned to ~34.6 hz. with about 12.75 sq inches of port.

ok. post up some pics of both calcs so we can see what the differences are

make the box bigger but what are the max dimensions you have to work with for the box? so we can make sure it'll fit.

the RE calc is known to not be very accurate. putting those dimensions in my calculator, i came up with around 43 hz myself. and to take screen shots, press the PrtScn (print screen) button on the top right of your keyboard. then open paint, paste it there, resize or crop if you need/want, then save it and upload it to photobucket or wherever you put your pics EDIT: ^what he said, tho i think 7 hz is a BIG difference between the two. i did see someone tho put their total length in the port in the 'length 2' box which told the RE calc that the port was that long, plus the length of whatever the box was. so it made it super long.

hahaha woooooowwww this thread was definitely NOT made for those replies lol yes it is, i have it hahah. i just hate hearing myself when i'm recorded, so i dont use it really. and you need headphones. but it's funny anyways

there is a 'golden ratio' to box sizes, as far as each dimension goes according to a certain volume for standing waves and whatnot. what i'm reading here says it's 1 x .7937 x 1.2599. say a box has a net volume of 2 cubic feet net. take the cube root, 1.26 ft, which = 15.12" which = side A. multiply side A by .7937 to get 12", or side B. multiply side A by 1.2599 to get side C, 19.05". so you have: side A = 15.12" side B = 12" side C = 19.05" that is just a basic description i have on here as far as that goes

i didnt even notice the distance at the 45 angle in the port lol. oops. and tyler, i've read several places, and from a member here (that i have good reason to believe...he has world records lol) that 45's dont help in the corners of the box. some people will beg to differ. i myself dont use them anymore, and havent noticed anything different. bracing stiffens the box, which helps output. the 45 in the port helps airflow out of the port easier, which would also help output.

put some dowels going vertically and horizontally down the depth of the box. from the port wall to the box wall, and the top to bottom. also, make sure to round over all the edges in the port, if you havent thought about it already. that'll help reduce port noise.

the distance is fine, technically it should be half of the port opening since both ports are sharing that space. but the port ratio is what may cause noise. i believe it needs to be around... 1:7?

oooh NICE part of the update goes in depth to explain all that and what numbers need to go where to account things properly. also, playing at frequency tuning does not mean that will be the loudest frequency played.

you have the most update version of .NET framework?
