SPL & SQ / Fabrication

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?

Anyone no what size t-nuts to use in double baffle box for 2 sa 12s

someone posted up a link to a SMdesigns thread that had a whole bunch of tips and help for building a good transmission line box. Whoever posted this up please let me know, as i am having trouble searching for it. Much thanks to anyone who has this link. Mike.

Hey all. Im looking for a design for 2 12 Sa's in my PT. My max dimensions are 39 W x 15 D x 20 H. i will be running them off of a saz 3500. Im looking for a cross between daily and burp if there is such a thing. Ive been told in the PT to run port up subs up with slot port inbetween the subs. I had someone making a design with cut sheets flake on me and I have to have a design by Monday when i have a shop to build in. I know this is asking a lot but if anyone can help me out it would be appreciated. the design can be basic as i dont have much room to work with. I just need cut sheet list and I should be set. Tuning should be right around 33-35 hz. and box should be righ…

i kno this is a stupid question but whats the difference in 1/2" mdf and 3/4" mdf?is there a big difference in sound?

how does this look? Used the RE calculator and it is confusing me a little bit. It is saying 4.58ft^3 volume with 105 sq.in. of port but when i do the math I get the volume shown in the box (in the drawing)... Sayd the tuning is 42Hz~ which is exactly what I am looking for but I wanted to make sure everything is good since I am getting conflicting numbers on teh box volume... Box is for a Mach5 SPL15

ive been hearing that the tantrum amp can actually get u put in higher power classes in some organizations because of the output at 4ohm..anybody know if this is true or not? and if so what organization does this.

wondering if anyone else is going to do SLAP this year, I am not sure because there are not that many shows near me, and I am tight on money to build for competition

how do you find out about competitions.? i've never heard of anything in my area like this. i live in cincinnati. which is a big place. but i guess car shows and sound comps are limited. or... i just don't know where to look

Wow another successful event! A special thanks got out to all competitors it would be impossible to have these events. A extra special thanks go out to all the competitors that traveled the extra distance. Team All Your Bass, Team Shattered Dreams, and Adam Metcalf from Trenton, Ontario!

Sooo...got a bit of a rude awakening today. Found out my e12a is actually presenting close to a 10 ohm load to the PG Tantrum 1200.1 in box - impedance rise is killing me. The sub is a 2 ohm DVC currently wired in series, and it's close to 2.5 times what I was thinking the impedance was. Pardon the extreme n00bish question, but is such a drastic rise common? It just feels a little strange running my sub at a lower impedance than my amp is rated for (if I drop it to 1 ohm), but if it models out well, hey...that's what I'll do.

I have a 2003 Pontiac Vibe and an AA Mayhem 15 and Im trying to figure out, ideally, what size box would give me best results and what way to fire my sub and port. Can anyone tell me how to figure that out? Like different variables associated with this. I was thinking sub up port back.

i am about to attempt to build my first box for my two db drive platinum 12s and a few friends have been telling me that a down fire box would be the way to go I am wondering if it really makes any difference in the bass level or spl I also planning on porting the box but I'm not sure where the best location for the port would be I'm new to all this when it comes to fabricating an enclosure. Its going to be about a 4 cubic foot box in an extended cab s10 with the port tuned to around 32-35 hertz. Any help or suggestions would be appreciated.

88120 TI - D3, well really a D4 so thinking some where around 2-2.5 cu ft. @ 32hz off of ~800w rms what do you guys think? Brandon

Powerbass xs15dv2 4.834gross volume 3.997net volume 63.375 sq inches of port (3h x 21.125w) 22.854 port lenght tuned to 38hz powered by orion 1200d @ 1ohm Are my calculations correct? If so do you think that is enough port area? 4.834gross 4.459net 42.245 sq inches of port (2h x 21.125w) 15.344 porth lenght tuned to 35hz Which one would you chose?

Hey all. I have my Fi SSD 15 in a box right now that is tuned wayyy to high. So I was crunching some numbers for a new box. Here are the specs, can you all look over them and see if everything is correct please? 28" wide 17" tall 28" deep Port: 4.5" wide 15.5" tall 41" long Sub up port back. 3.9 cubes net, @ 31hz, 17.88 sq in of port per foot Also with that box, should an SSD 15 hit the lows pretty good?

well i had the having the box where the backseats are located at, since i barley got the car and not ready for a wall i had this thoughed in my idea has it been done before? how does it sound? any mechincal noise coming from the woofer you think? idk if i worded it correctly. its ethier my recone them to 18's or recone them to 15's i currently have 2 10's dc audio xl woofers any input you guys? no idea if its done before to be honest, is my idea a complete fail or another way to feed my goal of getting louder any input will be helpful

im makeing this post for ppl trying to use fiberglass on there install's. this will help you understand how and what to use to make the job easyer. i will have more later and hopefully have a step by step so you can see it at work.... so here we go... the material's you might see is fiberglass this came's in many form's such as chop mat, cloth, fleece, speaker grill cloth and speaker carpet. next is the resin again came's in many form's, polyester and epoxy. these are the most used in the car audio world. other thing's you'll see is PVA, mold wax, MDF, bondo ect ect.... (and a few time's steel mesh, but i never used it.) ok now im goin to talk about resin. the resin we mo…

Can someone help with ideas for a new enclosure? Wanting to figure out the port velocity and everything . Model everything right for this one. . Trying to get a new computer so I can do everything my self and learn everything but in the mean time need some help.

Has anybody had any experience with Rear-Firing in Single Cab? I plan on doing this or downfiring. The only problem with downfiring is the max bottom depth I can do is 12.5" so the 12" sub will be on the surface of the wood just barely. I'm worried it might not be enough support because that will leave about 1/2" on both sides of the Sub Hole. (Where ever the sub will be, it will at least have 2 baffles.)

I am going to start on this project very soon so I thought I'd start planning right now.. Here is what I wanted to do.. I did not want to sacrifice my whole cargo area so I got my sub box made to take up only half of the whole cargo space so I can have half of the space to store things or whatever.. And then I realized that I have no place to mount my kicker 2500.1 which is a fairly large amp so I decided that I would want to build a false floor with plexiglass on the other half of the cargo space in front of my subwoofer box.. (as of now my amp is sitting on my rear seat folded down (i definitely do not like it at all and I do not want to mount my amp on the sub box as …

I've been tryin to find a set that will owkr well together 2 way active.. I think I've come up with it. It will be run off a old sony mobile ES xm-5046 choices (madisound) mid - either SEAS ca18rnx or L18rnx(aluminum) both 7" tweet - SEAS 1" textile dome 27tffn I believe either of these would blend well and work together in a active 2 way.. What do you think?? or WOuld both mids work or would one choice be better?? Thanks, Joe. P

I'm going to build a truck-style enclosure for a Fi Bl10 with a 3'' aero. Dimensions are w: 38 h: 12 d1: 6 d2:8 This is 1.217ft^3 internally. After the bl10 displacement it comes out to roughly 1.1ft^3. When determining the port length, online calculators asks for: Volume of Box in Cubic Feet Tuning frequency Port diameter Number of Ports I want to end up with a tuning of somewhere around 33-35hz, depending on how long of a port will fit in my box. So...... Do I put …

Hi, Can anyone help me with a box for one T3 Audio TSS 15 for a 1997 Acura CL? The CL is the Acura's version of a 2 door Honda Accord. My amp is a Sundown Audio 3000D. I can use up to 4.5 cubic ft. The box needs to be for SPL. Thanks to anyone that can help me some numbers.
