SPL & SQ / Fabrication

well since i put in the 2 15" BL's on the sundown 3000d, i have NO windshield flex, a little roof flex which is no biggie, but the worst is the doors...the body panels are so thin and theres just a single support bar inside it, which flexs with it against the body panel. i put Great stuff foam and peel & seal. i know peel and seal isnt real deadener, but ive used it before and itll deaden sound for sure, maybe not as good but itll do the job. well it did hardly nothing. what would solve it is fill the whole door with expanding foam but that isnt an option, becuase i obviously need the windows to go up and down. any ideas? pics of my door panels should be in the wall t…

Hey guys Im currently out in pursuit of the rookie1 world record in Iasca IDBL format.. I'm using 3 8'' mtx 5500 running them off a sundowns 1500d with a optima d34 up front.. Im limited to port area, 14 per sub so I'm basically playing with 42sq inches.. My current port is 39sq inches and Im doing a 140.1db on the audiocontrol meter.. In my class Im not allowed to use test tones so Im using tracks like 36 mafia-slob on my knob.. Is there any ideas yall could give me to bring my score up? I'm thinking of re-building my box to give each sub 1cub of space each with a solid 42 sq inches of port. Maybe try 45 degree fillers and fiberglass the inside of the box with external…

I KNOW THIS DOESNT HAVE ANYTHING TO DO WITH THIS FORUM BUT PLEASE HERE ME OUT AND ANSWER THIS!!! I'm holding off on the 4 BTL's just for now until I get my money right but for now I want to know if this is a good setup? I plan on buying 5 of these (To Save Space) http://www.sonicelectronix.com/item_3835_Kicker+05C84.html This amp for subs http://www.sonicelectronix.com/item_9551_H...+TXi+1008D.html The box is going to be custom made (To fit the trunk) (Ported) maybe tuned to 27 Hz.,is 27 Hz. loud or should I tune lower? And its going in a 2004 Chevy Aveo. Im going to parallel wire the 4 ohm subs to 2 ohms. For a educated guess do you think I'll be hitting @ leats 140db? I…

I'm just curious what are the advantages and disadvantages between TL enclosures, 4th order bandpass, and 6th order bandpass enclosures. These are all very new to me!

Hey all... got another question here . If you use aero ports, is it possible to build the box smaller in relation to a box with slot ports, or is the port displacement the same for both types? Thanks

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?

I have an 05 denali and want a 5 cu ft. box made. I went on re box calculator and my measurements I typed in made the box not square. Could someone give me a hand and give me some dimensions or a drawing???

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..

OK i got this box made 4 yrs ago for my other car but it was a ported box for 2 12's. It was for 2 pioneer premiere ts-w12prs subs. Now i am not sure what the sub actually calls for on ported box but the is a review & Klippel Data on this sub here http://www.diymobileaudio.com/forum/...newthread&f=24 Its a slot port box btw The box is pretty big Here is the outer dimensions of the box Height:12.5 Width:36 Length:26 I am using 3/4 mdf wood Here is the port length Width: 4.5 Length: 11 Depth: 18 Here is the specs of my w12gti's http://manuals.harman.com/JBL/CAR/Bo...2GTi_rev_f.pdf I am currently using this box on 2 w12gti's with a sundown 1500d at 2 ohms which is 80…

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

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.

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…

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>

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…

I've recently wanted to start making a horn style box, I've build one on accident before, but didnt know it was a horn box. Now im just needing some advice or basic tips on building and tuning of them.

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

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

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.

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
