  1. I need help guys! Is there anyway possible someone could draw me up something on sketchup or something similar for two skar ma-8, they are recommended 1 cuft per sub tuned to 35hz, I have no real experience designing boxes and all help would be greatly appreciated
  2. Just got a new enclosure design for 2 12 AB subs, the port is 3.5 inches wide. I showed a friend the design and he is said the port should be wider. What is the concept behind port size? Bigger louder? Smaller cleaner sound? Is it a calculation? Or is it just based on personal preference?
  3. So I'm trying to design a box for my 2 zv3 12's, i have installed 2 bucket seats in the rear of my 02 chevy pickup, and things have changed a ton in that truck since i last posted here. I plan on doing 2 zv3's in a ported box in between the 2 seats, almost like a tall center console. i found a 3D model of a zv3 12 on a different fourm, but i cant get the person to respond with a link to a download. Im just trying to get an accurate look of the box, and also having a model of the sub would be cool
  4. Hey guys, Building a box for 2 Treo RSX 10's for my wife's Jetta. Manufacturer's specs for 1 sub are 1.3ft^3 net volume with 12"^2 of port area at 14"long. Thus, I am thinking of building 2.6ft^3 net with 24"^2 port area 14" long. Anyone have any experience with these subs/their tuning and can tell me if other specs might sound better or if I am on the right track? Any direction will be much appreciated. Thanks!!!

    Port design question

    In regards to the image, here is my design for 2 warden 21" subs. Box is about 17.5 cubes total after displacement and some bracing. Port will be about 12" wide by 22.5" (internal dimensions) long about 33hz tuning (270" port area). So my question is, I can leave the spot underneath the port without a separator wall, or I can add a separator shown on the right. Aside from adding bracing to the box, would it lower port tuning a little? (in the thought of the air will hit the divider and move up, as if adding some port length?) If the subs allow I may make the port slightly longer, but tuning would max go to 31hz even if i add 6 inches internally to the port. So I dont think I will extend it if the box allows. The port will be pretty close to both woofers. I intuitively don't think it'll affect port tuning, but would it cause any issues adding the separator almost up to the port? Or if anyone has some input on changing where the port goes. The sides are very close to the vehicle walls so a port to the side may not be the best. And there isnt room to port forward.
  6. I got two dc level 4 15s im throwing in the back of my accent hatchback, as you can see all amps are wired up and ready to go, just gotta build box, but I cant figure out what would be best.. its going to be a big and tall slot port box, if port is to the rear it will only have like 4 or 5 inches clearance from hatch, i noticed walled off setups are always port and subs forward and sound great but also hear to always point it backwards... with my setup, what do you think would be best? after i build it, its gonna be hard to turn around and experiment so kinda have to do it on first try.

    2 X15 Sundown Box designs

    Please help. I need a box design. Sundown says 4.5 but I was thinking 5.5 because I won't be pushing the to full tilt. Less power = more box from what I'm told at least when it comes to sundown. I need something around 50=w, 30=d, 20=h tuned to 34hz. Any help is greatly appreciated especially old build sheets. Thanks guys!!!

    Box Advice?

    So this was my first time trying to build a box for my sub, i used a online calculator for the port, but i screwed up the box a bit, i did not subtract the thickness off the wood so my box has less volume than desired, and my port tuning is higher than desired. on top of that i had to change how the box was built bexase my wood was only 24" long ways and i needed a 26" side. so im gonna keep dumpster diving for wood and when i get enough of the same im gonna go for it again. My gole: hit as loud and as low as i can (if i can slam that low 0:49 or so in on Big Kurt - My Sub ile be happy) amazon recommend 5-7'^3 for my sundown X18 and im assuming bigger means louder to i tried to aim for 7 @ 28hz but got 4.9 @ 33hz. here is a pick of my first box Im gonna build a better box but not be concerned weather the next one will fit in the car. ok now your filled in, here comes the advice part. i have really limited access to tools. at my disposal i have a 40 year old craftsman jigsaw that cant cut threw wood this thick, a dremel with quite a few bits, one of those switch blade saws for cutting down small trees, and i can go to my great ants house and use her table saw, but its like 50 years old and really small, so i cant use the guides because the wood is to long and i cant cut at angles. oh and if i go to her place she has fancy new jig saw that can cut thick wood. so with the tools i can use, any advice on getting low loud power? and is using larger recommend size better or should i shoot for 6'^3? and for the volume of the box do i need to worry about the space the port takes up or the woofer takes up? and incase it helps, a vid i made on the sound of my box . along with this showing my response at least in my house.
  9. Ive got a box designed for my 2002 chevy 1500 ext cab. The box is 9.0ft^3 and im putting 2 sundown x15's in it on 2 sundown 1500D's @1ohm. I have the box designed with 3 4" wide tube ports, and for tuning at 30hz, it was somewhere around 10 inches for each tube. Will this be enough port space for these subs? Im not exactly sure the requirements on the port size or area. I originally had a box designed for 2 DC level 4 15's, but decided I was going to go with sundown instead. The box size was 7.5ft, but now 9ft. Any suggestions on port size, will 3 4" ports be enough? Thanks for any help guys
  10. Alright so I got like the slotted port down and how to make sure you use enough port area and everything but I'm confused on how to find port area in an aero port. The box I'm building is a 4.33 cubed box without displacement. 2 T0 12in rockford fosgates are going in this. The guy requested to use aero ports so idk anything about them really. Please help. Im starting from scratch really on the port.
  11. Hello I'm looking for a slotted port box design around 34hz for 2 sundown sa-12s. Its a trunk car and has max outside dimensions of 34"wide 15"height and the depth can be no greater than 22" Subs will be firing back towards trunk powered by an ampere 2000w amp, would like the port to be firing back as well. If anyone has designs or will help me create one i'd appreciate your help! Thanks!
  12. Hello i currently have a 3.6 cu box tuned around 36 hz with two 4 inch aeroports 12 inches in length. the box measures 34"w x 16"h x 16"d outside dimensions. i want a new box for my 2 sa 12s that will work perfect with the new bc2000d amp that is on its way looking for something for rock and rap styles of music i would like to try a slotted port design with a flush baffle for the subs. i currently have the box firing into the cabin and would like to do the same thing with the new box. i have 38" x 17" x 17" max space if it is firing into cabin. the car is a 2011 ford focus ses sedan. if you guys could give me ideas, designs, tips, anything i would greatly appreciate it!!!!! THANKS!

    X-15 D2 Box Help

    I recently purchased a Sundown Audio X 15 D2 paired with a scv-1500d.Ihave never built a box before so I had a local shop build one for me. To my understanding this speaker preforms best in a box tuned to 32hz. I told the shop that I need this built to this frequency but I believe they did not. They built a slot port box, 33.5x20.75x16.5 with a 15.5x23x4 port, with 1 inch wood. After calculating this on numerous box calculators I come up with around 40 Hz. I'm interested in knowing if these calculations are correct and if so what, if possible what the correct dimensions should be with this box. The 33.5 and 16.5 are maxed out on my trunk space but it could've been built up to 8 inches longer. Thank you for any of your help.
  16. I took Andrew McCullough's recommendations for HDC3 & HDC4 box sizes & tunings here How do these specs look for an HDC3.118 (copper coil) being run of a FSD Audio FZ2600? 5.20 Cubes net 33.03 Hz tuning freq 9.66 Square inch port area per foot (8" x 18" aero) 18.5H x 36W x 21.5D (1 baffle on top 1 on both front and back). This is for music btw.
  17. 1.5" x 1.5" Thickness MDF Is the bracing blocking the aero port out too much? I was thinking about maybe removing the center vertical bar or the horizontal one, maybe even both.
  18. Here's my box design so far for a SoundQubed HDC3 18" Box Specs: 20.75H x 35W x 21.5D. Displacements used are .23 (Sub) and .05 (Dowel rod). 5.95 Cubic Feet @ 30.26 (Cubic feet might be slightly higher due to window). This also takes into account 3 baffles and port outside of the box. Port Specs: 19" total length 7.920" Inside diameter .240" thickness, PVC 12" outside flare diameter 49.24 square inches port area. Still deciding on an amplifier, should be anywhere from 1750-2250W. 1/0 OFC Big Three. 150 amp stock alt. XS Power battery to come later. I still might go slightly larger on the box, every 1" wider gives it .20 cubic feet to net. I know people use 45s in slot ports to smooth out air flow but should they be used in aero port boxes? If so should I just use a 45 for the corner next to the port or all 4 corners? Thanks guys!
  19. Hello everyone. I am trying to build a box tuned to 30 Hz for three Ground zero GZRW 30 XSPL D2 speakers. I believe best box size is 180 liters, but i don't know what size slot port should be. can anyone help me? Number of drivers : 3 subwoofer Xmax = 40 mm thank you! edit: Is it okay, if i will use 400 cm^2 vent area?
  20. Hello, Reading around I was not able to find a definitive answer to my questions, so I decided to take the initiative and experiment myself! The question in mind is one alot of people seem to be having. WHERE SHOULD I POINT THE PORT AND SUBWOOFER TO MAXIMIZE SQ/SPL/SOUND TO EAR. So let us get started shall we? The truck in mind here is the ford extended cab, which is the same for many years(if someone can be more specific, feel free to chime in). These same boxes could obviously be used in other trucks, along with cars. THE RESULTS HERE ARE ONLY SPECIFICALLY APPLICABLE TO THIS GENERATION OF FORD EXT CABS The questions: 1. Does it make a difference where I put the box? 2. Does it make a difference if I fire the ports sideways(and if so, which way?), up, back, etc? 3. Does it make a difference If I fire the driver down, forwards, backwards, etc? 4. And finally, if the above does in fact make a difference, Which way is 'best'? The above questions, and any others, I can answer with the experiment. This will be done so and documented over the next week. As of now, I have designed the boxes in SketchUp, and layed them out in WinISD alpha. Both are EXTREMELY close on the Magnitude chart, so it should be as close as possible of a comparison. These boxes will be number 2 and 3 in my building career, however the first one turned out great Attatched are the SketchUp files, as well as the project in WinISD alpha. If someone, or multiple, would look over the designs to make sure I did not miss anything and got the ports right, I would GREATLY appreciate it. The more eyes the better, right? Boxes: The boxes have IDENTICLE outside deminsions, and are extremely close in NET volume(not perfect due to different double baffles) Tuned to 34.14 and 34.70, respectively 1) has the sub firing down, up, or forward depending on how I flip it, and the port to the side. 2) has the sub firing forwards, and the port up. This one could also be flipped to make it sub up, port any which way, or even sub back. The drivers to be used in this experiment are Sundown X-10 Version 2. For later experiments they will likely be switched to SA-10s, as the X's will go in a future build. This experiment will be extensively studied, as it will help me, among others, with future builds. This is my way of beginning my contribution to the community! WinISD alpha file:

    port size and shape help

    Ok so im set now on getting a dayton ultimax 15 for my sub stage in a 4cubic foot box tuned at 25hz... i want dual ports so that the box is symmetrical, so areos are the best option. Im trying to figure out how much port area i need for this sub. Problem is the tuning is so low that the port has to be long. Going a large port area makes it a really long port and making it smaller may give me port noise or not enough port area. Any help on this would be nice The sub im getting The box will be made out of solid red oak wood made for counter tops. 1.5" thick all around. I plan to use 1" round over on top and side edges and then do a nice dark cherry stain on it.
  22. Heard that these subs like big ports but still not quite sure exactly how big to make it. The box is 4.5 cubes and I'd like to tune it right around 32hz. Haven't cut any wood yet so I still have time to size it up or down if necessary. Would a 5.5" x 12" port work well for a single 15? bigger? smaller?
  23. Hey guys, So I've decided to go ahead and build my own custom box for the first time but I had a few questions before I did so. I understand how to calculate port size, depth, tuning, box volume, the works, but the only thing I'm really unsure of is where the best location for the sub relative to the port would be. I am planning on running a Soundqubed/AQ HDC3 15 tuned to 32hz in a box around 4 cubic feet. To get it to hit hard should both the sub and port be facing toward the rear, top, front, does it really even matter that much? If possible I'd like to have the sub mounted upwards in the center of the box with a slot port on the left rear side (when looking into the car from the rear aka. drivers side) but am open to any suggestions that may lead to a better sounding setup. My car is also a mid sized hatch-back if that helps. Thanks for your help.
  24. soon to be LOTS of pics... start this a few days ago. i built a prototype awhile ago but looked like shit, so this is the FINAL concept with the built in amp and even some lights. not the best picture taker, sorry. and some are working at night with poor lighting. pictures of the starting holes for the dual dayton RS100-4 speakers. also shows my HAND MADE circle jig able to cut holes up to 40" in diameter
