SPL & SQ / Fabrication

just like it says if someone has experience with a 72' bug and or a BTL 18 I am looking to redo my box and need design help. Please PM me on here. I just know I can get louder than 144 with a exile 2400.1 and a standard BTL with cooling. Thankx MC

its a box for two Fi 15 ssd's. the dimensions i have are 42"w X 20"h X 22"D total of 8.8cu.ft and total of around 8.5cu.ft with sub displacement. and a port 8"w X 8"h X 13"d would tune it to 32hz. thats the calculations i came up with,i just want to double check before i go cutting up mdf.

okay guys, i am lookin to build a new box for my 2 12" kicker cvr's, i am wanting around 34hz for tuning and here are the dimensions i have to work with, 39"w x 17"h x 17.5"d and plans would be great i am either looking for the port and subs facing the same direction or subs foward firing and port side firing, any plans would be nice, and i am looking for a slot port, i am not going to mess with a pipe since i dont have a hole saw, thanks in advance.

I will be building 2 of these boxes sometime in the next week. There are matched to fit my tiny trunk (00 Mustang Vert)Each is 0.86896 cubic feet, tuned to 32 or 33hz. Each will house a CompVR 10 inch sub, Seeing around 400rms each. The boxes are from a friend so they will be free. There replacing prefab sealed boxes about .8 cubes I would like to know if theres anything wrong with my design. The port is 12.5 inches wide, by half an inch tall. It extends all the way until it is half an inch from the back wall.

i talked to my cousin earlier and he was explaining different box designs to me, he said that he had a box that was a cross between a t-line and a horn design box, he sent me an attatchment w/ pictures of the different types but i cant find formulas anywhere, i used the search but none of the links for formulas worked so i was hopign someone could help me out... thanks

hey guys have 2 18" smd subs, have xtra cab f150,trying to do NW have 20d x 24h x 57w so i have 11cuft = 5.5 per sub,trying to get into the 50's but i cant seem to get there, any help appr.I have interchangeable port spl port 17x 13 thats the biggest i could fit, subs up on passenger port up on driver,double 13 ply birch all of box,running stetsom 7k2d 4xs power batts (2700's) 1 h/o alt ohio gen.4 runs 0 gauge 2 pwr 2grnd to the 3 batts in rear,should i just go for the wall? i'd get about 20 cu ft. SSNW1-2. ANY HELP THNKS

i should have the money soon for the zcon 15 so i want to start getting ideas and thoughts on a box size for the sub. im putting it in my '95 ranger. for electric, i have a iraggi 260amp alternator, big 3, shuriken bt60 bat. and all 0 gauge wiring. i have a audioque 3500.1 that i will be running at 2 ohm (should have 2000watts which is plenty for 1 zcon 15) reason being is that it will be much easier on my electrical, and easier on the amp as well. im more for SQ on this build for those wondering. i love the low lowsss haha. i havent found any box recommendations so im looking for a bit of help. any is appreciated!

Alright well my buddy has a misubishi eclipse with 2 12" alpine type E's in it right now. He ordered two more today. So I dont have any dimensions but I want to make a ported box tuned to 31 hz. And probably 6 cuft. But should I make one big box? Or should I seal off the subs?

o.k. i am not happy with the numbers i am seeing from my wall.so my q is can i cut a hole in the back wall and take it in to the trunk or make like a C in the back to make it deeper???i know it will change my vent and tuning.i am not worried about that.

Hey guys I was wondering if I could get some help for a box design. I messed up my first design as my box fits inside my car but I FORGOT to measure the opening of my trunk to put the box in which doesn't allow it to slide right in. I am coming to you guys for a design for the Fi 15" BTL. And the car I have is a 95 Honda Accord. Max width I will go is 35" and the height will 16.5". Was looking for maybe 4 cubes of space @ 35Hz. I would really appreciate the help and thanks in advance! -Curt

I'm wanting to know if I build a box like this and would it be ok with the ports like this. It would go in a 95 honda accord 9.67ft^3 gross, 7.34ft^3 after ports, after bracing somewhere between 7 and 6.5cubes after bracing, depends on if i invert it or not thanks for any suggestions or comments

I am wanting to add more low end to my truck and I think I have decided to do a rear console. But I dont know which way to fire the sub or subs. The box will be roughly 2.4cu and is 14x28x14. This is going in a 07 Harley F250. Here is a few pics of a cardboard make up box. So should I do one 12 rear facing and ported or do 2 10's or 2 12's down firing sealed? If I do a down firing box it will need to come up 2-3 inches so it would be alittle higher than pics. The box will be black carpet to match. Looking for hard hitting low clean bass. I could maybe get another .5 if I slope the front and bring it down. Looking at either SA-10's 12"s or SSA Dcon or ICONS and a SA-1500…

So I just bought a single Nightshade 15 for the trunk of my 2007 300C. I'm just gonna figure out what works best for the box so as to not block my spare. I was considering porting a box towards the back seats, with the sub inverted on the back of the box (so you can see it when you open the trunk). Any problems doing this? Having the sub inverted would let me fit the box more tightly towards the seats in my opinion, but I'm new to box building. Thanks for any help

Hey guys, I just finished my box. Was all excited, i did i dry build first. just screw it in before glueing. After I built the box I take it outside only to find it doesnt wanna go in my car. YES I did measure twice and cut once, but i failed to measure the clearing distance of my trunk to slide it in. Here is the plan I went by 4cuft. at 35Hz Is there any way I can sacrifice any depth when putting this in my car? Height: 17" Width: 39" Depth: 16.25" Thanks for the input and flaming, Curt

ok, so i have the dimensions for everything, but i want to make sure if its all good, also if someone could do a sketch of it? 2 - 15" nightshades 1 saz-3500D 99 s10 ext cab subs forward, port in the middle firing up but along the back wall of the box. box height - 27 depth - 14.5 Length - 46.5 Port height - 6 width - 16 length - 26.25 net air space 6.68ft3. port area 96.00 in2. @32.19

I need some help would u guys recommend a figerglass box and mdf or jus an mdf box I don't know much about mdf an fiberglass boxes it's for an 18" btl

I have designed a box for a friend of mine. He also has an 86 F150. He heard my system and wants to use my type of subs. The pioneer TS-SW3041D. I have designed a box for him and just wondering if it will be optimum for the speakers. Heres a quick drawing i did in paint: Can someone here that has a proper box building program plug the specs in and tell me if this box would be good to use, or that i should start back over. Any and all help with be greatly appriciated. Thanks in advance, Scott

Alrighty then. So im trying to decide whether to wall off my new system or having port back subs up. What do you guys think would be louder. The dimensions i am working with are. Length 53 , Width 49, Height 47. The system i plan on doing is two Fi BL 18s with two Sundown SAZ-1500d. Thanks, Kasey

i currently built my first box ever...and it came out pretty good...there are some minor gaps...which i believe are due to warped boards because all cuts were made by me on a table saw...but back to the point...i siliconed the crap out of the inside and silicone into the port (around the port pieces and one of the other corners) will that change anything such as tuning? or increase the liklihood of port noise etc?

hey guys, I have recently purchased a 2006 subaru legacy 2.5i. my previous car i had 2 12 inch gcons on a sundown 1500 amp, a 6 cubic foot box that i sealed into the cabin. was wondering what would be effected if i were to seal the box instead of port it and still reverse the subs facing the cabin. so run a 3 cubic foot box sealed off from the trunk with the subs facing the cabin. i just am wondering if this would work. or if it would sound like shit. haha. i have the box designed to fit into the trunk so i can seal it off. I am trying to save space (i snowboard in the winter) roof racks can only carry boards. id have more than half the trunk left with the box ive designe…

How can one calculate the box rise and how does the shape of the box, etc. affect box rise? I am interested because I want to wire my subs down to .5 ohms, and I hear that it probably wont be an issue because of "box rise."

Ok guys, I was looking into a few stats on bench testing, and noticed that amps wired to ".5 ohms nominal" could see up to 1.5 ohms in reality. So, with that in mind, I read into box rise and all that good stuffs. I was just wondering, If I skip terminals on the box altogether and run wires through a small hole (that would be sealed up after of course) or out through a port would this help at all? Or would the longer length of wire just defeat the purpose? Thanks in advance, as always.

What is box impediance rise and how is it calculated.

hey guys...just wondering what u guys would recommend to use or have used to keep your box from sliding around? i have a trunk car so mine just moves all over the place...? velcro? l-shaped metal corner brackets? open to ideas...

I bought a box i just saw some of the glue is coming undone so im gonna glue it again and screw it down and seal up the inside. But i need to know what it is tuned to here are the measurments thanks in advanced. I have an L715 in a ported box the measurments are 16" h 40" w 17.5" d and the port is 3.5" w and 13.375" deep. I would like to know how many hz it is tuned too and how many cubic feet it is after port and sub displacement. Thank you
