SPL & SQ / Fabrication

bought a 18" ftl fully loaded for daily, and i was wondering if anyone can design something for me. max dimensions are 55 in. x 20 in. x 26 in. doesnt have to be exactly those sizes, if i can go smaller i wouldn't mind at all. this is going in a ext cab f150. going to be used for a daily ground pounder. any help would be greatly appreciated.

Whats out there thats relatively beginner friendly? I want to see if I can do a ported box for 3 MJM-18s or 2 IXL-12.2.2s..

Well heres the plan. Thats the rear window in my cab. thats the front window in the fiberglass camper shell... I plan to take out both windows and run a gasket between the two. I've heard that you use some kinda RV gasket... what is it called? As far as I know I'm going with two IXL-12s and a 2500D. Would 3/4 MDF be thick enough (Rona has no 1").. I didn't check any other stores.

seen it a couple of times during my visits to select products site. anyone try this stuff? i am trying to get a better idea of the result i would get with it. my car has this felty suede material in the center console and ashtray area. is it similar to that? i was thinking of using it to line the bottom of the amp rack and wanted to know if it is decent or i should just do real suede?

Where I work we have this non-flexible polymer composite called synthane and it comes in 4X8X3/4 sheets. Now I was wondering if this woould work for a box? I mean in theory it should, its dense and non flexible. I was just wondering if anyone has ever head of this material. I highly doubt its ever been used as in a box, I would imagine its very expensive.

I am designing a slot ported box for a bl15 fully loaded. I am looking for 4.18ft^3(4.0 after speaker displacement) @ 32hz. I just need to make sure I got my measurements right. The dimensions(external) are (H)19.5 x (W)45 x (D)14.5. The port is (H)18 x (W)4 x (L)38. Am I right? And is 72in of port area to much? Oh yeah 3/4 mdf is the wood I'll be using.

Alright I am trying to figure out a design for my car. Box is for 2 15" Nightshades, with tons of power, Jacob said I only need 2.5 cubes per sub. Anyways my dimensions are 30" deep, 16" tall and 31" wide. Only way really to fit this is if I do subs up. Now I wanted to do external aero ports blowing right into the car, but that won't fit. So now I am thinking A. aero ports blowing in but internal, b. aero ports blowing to the side, but internal, c. regular port facing in, d. regular port to the side, e. regular port to the rear.

I was looking @ this video and this guy made this video with 4 15s and it was 2 of them at the top and 2 @ the bottom.Anyone an expert on making these kind of boxes I want one made in my car. here is a link <object width="425" height="344"><param name="movie" value=" name="allowFullScreen" value="true"></param><embed src=" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>

Hey guys. I just picked up a new RE SX 15. Its going to be powered by a Sundown 1500D in a '08 Scion xB. I need help designing the box though. RE calls for 3 cu ft minimum, 4 cu ft optimal, and I would like to tune for 32Hz, sub firing up. The sub displaces 0.18 cu ft. The dimensions I have to build the box are 38.5"x18.5"x19". The pictures below should help to visualize. If there is too much space there, I'd like to cut a couple inches off the height, and then if still too much room, a couple off the width (18.5"). Help needed! ~Trevor

Alright guys i'm in the market for a system ( my first ) I have a 98 Z-71 EXT Cab so i have more room than needed. I'm wanting 2 fi btl 15s & 2 saz3000d's or 2 1500ds.....the problem i'm having is idk how to build a box lol Nor do i know what kind of wiring to get, if anybody can help me please help

If I do my setup the way I'm thinkin, looks like I can only fit tens. Max diemensions is 34 w X 15 h, I'm pretty certain. I've got the rest of my truck bed in regards to length. I've got a few ideas.. Lemme explain this. First off, these are overhead view of how the box would be. There not to spec or anything, just some ideas. Its not the right diemensions or anythin.. just some ideas how I could fit a few 10s. Would fire into my window. The first one, top left, is a sealed box, kinda based on a clamshell on its side. second one has four subs, and a port in the middle. Bottom is just a ported box with two tens firing into the window (not sure if you could fit two tens an…

Well i installed it mid june(?), everything has worked great. Whenever i took people, they said my truck smells weird. I never really thought about it, but last weekend i drove a group to the football game (they chose the guy with an 11 mpg truck to drive 1.5 hours there, wtf lol) and took the box out for the ride up. When i put it back in a couple days later, i noticed the smell. I guess i just got used to it, and never noticed. I know it's not my sub, because it can smell funny when i get in it for the first time in a couple days, when nothing has been playing. I really can't describe it, it's a mixture of things. Wood would definitly be one smell, but could it be sili…

Hey guys, my friend has a Ford Ranger and he asked me if having the port facing the door or roof would be louder. And I decided to ask on here for him. Reason because he is getting a box designed, what would the pros/cons of having it facing either way be? Thanks in advance.

Does any one know how i would calculate port height width length 1 n 2

ok so i have built a few boxes now always using slot port and designing them myself and what not... but slot port always takes alot of space up... i am thinking of using aero ports.... now but it is hard to get exact sqin of port that i want... anyway my q is they displace less air correct... and if so i know it depends on length but is it a dramatic amount thnx trunk cars sukk

i need a free box design program to run on my mac thanks

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

which way should i do my box design for a btl 18'' with two 6 in aero ports. sub up, aero back?

What makes this sub the happiest on daily?? It will be built out of birch ply, fed about 2ooo watts and space isnt a issue.. helps appreciated.. Im not asking for a box design, just what volume and tuned to what, I can design.. Thanks in advance..

So tonight at work I was discussing my upcoming sub build with a few guys. One of the master debaters argured that stuffing a sealed box with poly-fil was recommended and the other said it was a joke. Yes? No? Why? Thanks.

ok so my bro has a 15" l7.... seems to be alot of these mentioned in the forum lol. right now its in a sealed 1.5 cube box. a kenwood kac something something powering it with 900rms. car is a mercury sable with the mach audio system. currently the amp is using a loc to get single but my bro will be geting a mtx req or similar device later this year. theres no deading in the car and it rattles like crazy as is.... sorry to anyone who has heard and affended by the rattle... hes geting like 2 rolls of raammat for xmas from my parents we picked up some mdf and liquid nail today and plan to do a new box for the sub. im hoping to do a ported box with a pretty spl oriented de…

I purchased this sub on closeout from Parts Express earlier this year when TC-Sounds was filing for bankruptcy. My daily enclosure is a sealed pair of RL-i8's. I'd like to build a ported box for this single TC-Sounds 12" sub but I'm a complete noob when it comes to enclosure design. My typical listening style is loud SQ; typical artists include Smashing Pumpkins, NiN, and Daft Punk. Any suggestions? This is just for fun, so feel free to be creative.

sorry if this is in the wrong place, i wasnt really sure where to put it. move if needed. i just know lots of RE questions get asked so i'd thought i'd start it here. i posted the same thing on caraudio forum and thought i might as well post it here too. if anyone has any ideas i am open for anything. -getting around on a build for an 18 inch 2005 xxx. ive done some searching on box sizes and such for this and i am thinking... 8 cubes 34 hz 115 inches of port do those numbers sound about right? bigger box? more port? this is going in a 97 grand marquis...huge effing trunk...FTW amp is a saz1500 i was also porting the rear deck and taking out the back deck speakers. was t…

my friend wants me to build him a box for his 2 12" lanzar vibe dual 4's and i cant find any specs on these subs let alone what cubes/tuning freq. to build for, its going to be ported for SQ-L if anyone can help me out. thanks and aparently if i try to just type SQ-L without the dash, i get LSQ?
