Ok, now, i need someone to DESIGN me a sub enclosure for a FI BTL 15" Ported ~34 hz

cant be more than 16.5 in tall, 34 in wide, 18 in deep..... shouldnt need to get that big now....

I love google sketchup, so if someone whipped it up on there, then i would be forever gratefull

You're using 1" thick MDF?

what do you think i should use?

.75?

i was told to go thick....

I used 3/4 inch and i think most people do.

1" MDF if you can get it is great. You would most likely depending on how your port is set up, not need bracing in it.

Most of us use 3/4" MDF do to availability. If you have access to 1", by all means, use that!

ok, the last box i built, i used 3/4 and it worked fine...

how will those dimentions work?

and does anyone here have google sketchup? i built the box on there and it looks like its gonna be nice...

You can download google sketchup free (just search it on google). Its not to hard to figure out and comes with a tutorial.

are you telling me?

i was asking if anyone had it cause i was gonna sent them my box, but you have to have sketch up to open it up

Sorry lol i thought you were asking someone if they had sketchup so they can design your box. Read that wrong.

Have you decided on the thickness of the wood your using? 1" may be a little thick for those dimensions ex your height is 16" so your internal height will be 14" and the 15" cutout diameter is 14.125" see what I'm getting at. Also using 1" wood with those dimensions you are under the minimum box requirements of 3cuft.

yo man, that sounds like a great box! be sure to post some pics of the build. don't forget to make sure you actually angle the box into your trunk before you have it all assembled, mine was right on the edge. almost had to grease it up to get it in

ok, ill do 3/4" wood

and caligreen... the last box i built, it was 34 wide, 18 deep and 16.5 tall...

we had to round the edges just to barley be able to get the beast in....

as a matter of fact, i got picstures!!!!

photobucket is being gey right now, and wont let to my album...

but it was beautiful

your going to need to recalculate everything also if switching wood thickness.

i know....

im already all recalculated

lol

so. what frequency do i want?

i listen to like all rap

like 32? 33?

either one would be fine. 33 or 32

haha nice, i know what you mean about trying to cram a big box in a little japan trunk! i think you're going to like this woofer a LOT more than your type R's. now it's all about getting power into that btl because even though it's so efficient and will play very loud with very little power it will just keep getting louder and louder until you can't throw any more power at it. 33 or 34 maybe? the lower you tune the more of your box will be used as port and not airspace.

Id do something like this.

and this is why i love the ssa forum... :bigclap:

kinda confusing... :-P

why a double baffle?

and what options should i get for the sub? ill be running it with a 2600Watt hifonics....

which probably does like 2300 or 2400 watts...

watts = amps x volts... so unless you got a 180amp alternator and a couple runs of 1/0 i don't think you're going to get the most out of that amp, or any big amp for that matter. you're definitely going to need a couple sealed batteries to get the most out of this system, and probably a new alternator down the road. i can't even provide my sundown 1500 with enough juice lol.

Double baffle because the sub is a good 40 to 50 pounds and it will also cut down on enclosure flexing.

well its not confusing, i just dont like the format, i had 2 45 lb subs in a singe baffle and had no probs.... idk, ill see... only if i got enough wood left on the sheet

ok caligreen, but what options do i want for the sub?
