SPL & SQ / Fabrication

Box should net 1.5 cubes, i was told to tune around 33 hz so i am in between sq and spl, im not looking to compete or anything, its an underseat box in my silverado (3 inch seat lift to gain space). I was told already here that best to face the port towards the rear pass door. My problem with that is that i have a maximum of 6x3 for port area there. Which is bare minimum for port area going by the "general rule of thumb" of 12-16 per cube, but ive read thats a load of junk. I tried winisd, it gave me a ridiculous port area. Im not sure what i did wrong but it came out over 100 sq inches. I did online calculators and got anywhere between 20 and 40 sq inches. So first off, …

Hey everyone, So I finally started building my first box that will hold two 2 10" DCONs Everything looked good as I thought I could achieve 2.5 cuft with some 44in of port at 11"x4"...... Well now that I have all the walls in, I have begun to realize just how new at this woodworking stuff I am. I can't post any pictures now so I'll try to explain this as best I can. Mistake 1: I have the port coming in on the left side, going in some 22 inches, then turning and following the back wall the last 22 inches. I planned on having 4 inches of width throughout the port but thanks to my amazing tablesaw abilities, I have 4 inches on that initial run, and only 3.75inches for the…

I was wondering if i could run two rl-p 18's in only 7.6 cubes sealed after the sub displacement. Sounsplinter suggests 4 cubes for each 18, so would running them in a smaller box not be a good idea?

as the title says im very interested in this i came across it on youtube watching some vids read the comments a let me know how it is done please

Okay, Im not much of a box-builder. Nor do I know any of the concepts to box-building. I was wondering for my MAW-15's, Which I'm putting in a 4.0 ^3cu. ft. box sealed, When I get the box built does it need to be two independent chambers with 2 cu ft on each side or 1 big 4 cu ft. box. I wasn't sure what if that had an effect on the subs and/or their performance. Thanks in advance. ~MadroX

I cannot decide on what to do. 4 SA-15"s in a standard ported wall, or 4 SA-15"s in a 4th order bandpass. What are the positives and negatives of both? I've helped build a 4 15"s wall in the 60's and an 8 12"s 4th in 60's. I like them both, both sound good, both played well. I just cannot decide on what type of enclosure to build.

hey, i know im a little premature since im still looking for a vehicle to build up , but where can i get a small sheet of plexi to etch for a custom logo? So far ive got most of it planned out. Ive got a pioneer HU, a damn near industructible class D amp thats stable to 1 ohm. Since i took all the stuff out of the X i just need to find another vehicle to put it in, and I plan on building a custom enclosure when i get the car/truck and decide on a subwoofer, right now leaning to one of adire audio's product line. Who know's , maybe once im done i'll even grace the local car show with my presence But for now im still in the planning stages. Could i order plexi online…

I'm thinking about getting a professional shop to design and install a setup of 2 10" Icon's for me. Reason being is that it's going into a trunk (not a show car) and I want it to be practical (able to put THINGS in the trunk again) rather than having a simple carpeted box ... I want it to look good! I'm thinking about firing in (seats can fold down), sealed off, all carpet ... They talked about covering the amplifiers ... covering my battery in the trunk ... But if I'm paying a shop, what are some options that I should inquire about? Removable plates ... Plexiglass ... Company Logos on the inside deck lid ... stealth on both sides of the trunk ... lighting ... I don't w…

What kind of Box you sugest for 2x Pioneer 307D2 just for SPL Street B class. Dimensions, Port, and other things. Thank`s

So I'm taking my setup to a 1x event in timmonsville sc. I'll finally be getting metered on a t/l, but I'm wondering what I should bring with me, and if anyone has any tips. There are 2 classes they said I could compete in, truck/suv or something else like extreme personal or something like that. I don't know what would be better, or if it makes much of a difference because like I said, it's my first competition. I've already been told not to do anything to drain the batteries before getting metered, don't know how sound that is or not... Just wondering if there's anything I should know before driving 70+ miles away tomarrow moring. ;D Thanks.

I'd appreciate any help you guys can give me on this.... I have a 12'' Nightshade on the way and need some help with the enclosure. I currently have a 10'' Fi BL in 1.6 cubes tuned to 35 hz in my reg cab Ranger. I know it isn't the prettiest thing in the world, but it's the optimum size for the 12'' Nightshade and I'd like to re-use it. My first problem is the mounting depth.....I'm going to have to add some spacer rings to allow the Nightshade to fit depth wise and obviously I'm going to have to increase the cutout to allow a 12'' 12 spoke basket to fit. I wanted to ask you guys what would be the best way to go about this? Should I make a few circular spacers around the…

just wondering how accurate it is or if it is super basic for the noob http://www.accelerator-pedal.com/ported-box.asp

I am in the process of building my car and I am wanting to do something different. I started out with 3 solox 12's but traded them for 2 solox 18's. I have 4 crunch Gp3000d's to use but I only have 18 cubes total to use. So i thought of using only one solox 18 with 2 GP's in a 4th or 6th order bandpass enclosure. This is for daily and maybe a once in a while bass race/street beat run. Would it be better to run 2 18's ported or one in a bandpass? If a bandpass how big sealed and ported.

Ok so I am going to build my 3rd sub box and i want to know how to cut the bracings and that stuff. And how to port/tune you box. I am going to put it in a car and i want the sub facing upward and the port too. I do not want an L ported i want like square type one. My sub is a 12 Fi SSD. I want it to use half of the trunk but not be so tall just like an inch after the sub fits. But mainly i just want to learn how to do square ports. Any help plz.

Height = 13Inches Width = 48 Inches split in half for two seperate compartments one for each sub. Depth1 = 6.5 Inches top Depth2 = 12 Inches bottem Now I donw know much about porting or tuneing. Im running two CVX's dual 2ohm VC wired @ 2ohm load off a 1500.1 zx This long skinny box fits behind my two seats in my pickup truck with one sub behind each seat. When my cousin made the box for me he put a board in the center to seperate the two subs so they both have different compartments. I wanted to maybe port the box to get a deeper boom. But i have no clue how big to cut a port hole... VentedCompact (MinimumEnclosureVolume from the manual CVX12 1.7…

I've always painted my sub boxes and thought i might try giving carpeting a go. I was wondering where you guys buy you carpet from? I'd like something cheap, but of decent/good quality. (doesnt everyone. lol) Thanks in advance

any1 familar w/ my make/model please help. I already have tons of flex in the frame all around the sunroof but esp. the front part of it, I am about to be installing more then double the power + batts + 0 gauge so I am concerned. I def. cant even listen to the music up with the sunroof open, hell I can't even open up the sun shade on it when the system is on blast w/out fearing a glass shower, so I have no problem doing something extreme to fix this problem or at least help with it. If shizzzon reads this I am very interested what you did or are planning to do with your scions sunroof. Thanks in advance for any suggestios or thoughts on this. - anyone who has any advice…

Without a good understanding of the proper way to wrap a subwoofer enclosure, applying carpet can be a daunting task. Allow me to solve your problems as I teach you how to rap... er I mean WRAP a sub box! If you enjoy be sure to check out my plethora of other videos! (Click the image for video)

Is tuning a ported box to 35 hz for daily use normal.

This is the final version of what's going into the back of my truck. (1) About 20 ft^3 box (2) ~15 ft^3 after port and displacements (3) somewhere around ~220 inches^3 port area (4) tuned to 32hz Thanks! * If you can't see the image then flickr is blocked where your using the computer.

Hey guys! Just made a video showing how to create a subwoofer enclosure in Google Sketchup! Go ahead and check out the video and let me know what you think!

I'm designing a new box and have a sort of kink in my design. I'm looking to do a baffle with a 30 degree angle in it. Now the issue with this that I do not know the clearance for the sub since it will be angled downwards. It is a 15" Havoc (standard basket), and I just wanted to know if anyone had any ideas about the clearance. I basically need to know how far above the bottom of the baffle the sub needs to be to clear the bottom piece. Thanks!

I have been trying to decide whether or not to go smaller with my box build. All of my buddies that are a little old school when it comes to spl say big boxes are the way to go... But when talking to people I compete with such as TJ in his Yugo doing 52's he says go smaller. My current box is 3.68 cubic feet after driver displacement, but not port displacement. 69 sq inches of port tuned to 42 hz. The woofers are two TC sounds OEM 10". I am thinking of shrinking down to a triple front baffled, double walled 2.4 cubic feet gross, and using 2 4" aero-ports and slightly raising my tuning as the change in box orientation changed my resonant, and building the wall (in the trun…

hey guys, im about to build a ported box to sit on my back seat, just for a little fun. amp is an saz1500d@1 ohm wired up to a diehard gold with 2/0 welding cable I realize box recommendations are 1.5 to 2 cubes ported at around 30-35hz with 12-15sq inches of port area per cube, but i was wondering if there was something more exact due to my lower power and config (being in a truck on the seat) its going to be a slot port because im going to use re's box calculator. oh and i planned on going sub firing up and port facing the windshield, is this a good or bad idea? im just looking for a daily street beater

so my RL-i 10 has arrived, now i'm waiting on the amp. my 1st question is this. would putting the driver on the back side of the truck box be a bad thing? i know to allow for excursion clearance, but it would still be pretty close to the back wall of the cab (regular cab ranger btw). would there be some adverse effects from the air the sub is pushing not escaping away from the sub fast enough? here is a crude 1 minute drawing. i was thinking if it would be alright to face backwards; i would extend the sides of the box to act as a separator between the box and cab. i've seen boxes like this before, but they were facing the front to give separation from the seat. this n…
