  1. Enclosure opinion

    Ok so here is the deal..I have a Nissan 370z so room is well very scarce. Before my Nissan i was running a 15 inch FI BL. After i bought the Nissan i bought a 12 inch Fi Neo Q because i just thought there was no way in hell i would fit the 15 in that small hatch. Being used to the 15 i hated the Neo Q it just wasn't satisfying to me. So I sold that and bought a 12 inch Fi BL and it was definitely better, not quite what I was hoping for but it was better. Months later comes a bright sunny day and out of boredom i just go to measuring to see if there was any way possible to get that 15 in there and believe it or not i came up with a box that would fit. Flip side to that though it that is bare bones minimum and there in no free space to make the box any bigger. After port displacement and speaker displacement it was around 2.95 cubes. I threw the FI in there and let her rip and believe it or not it sounds pretty darn good. In this car the enclosure is directly behind my head so it's pretty loud. My Fi is getting old and i was looking to upgrade. It did well on my hifonics brutus 2400 but i recently upgraded to the soundqubed 2200 and it seems to be a bit much for the FI (this sub is like 5 years old and has been through hell). So i was looking at the hdc4 2000 watt sub as an replacement. Seems to be a perfect match for the 2200 amp but iv'e read that it's a stiff sub and i'm concerned that if the sub is as stiff as people have said then being in a smaller enclosure may be a problem. Have any of you tried one of these in such a small enclosure?
  2. 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!!!
  3. I'm trying to figure out how many cubes and what to tune each side of a 6th order bandpass for a single sundown zv4 15 and how many sqin's the ports should be. It's a d2 rev2 and will be ran on a shark 3500.1 amp. Its going in the extended cab of my 2004 f150. I want it musical and loud lol. Any help would be greatly appreciated!! I new to building bandpass boxes and I could really use the help. Thanks!!
  4. Hey guys, im new to the site..been in the car audio scene for years though. I have a custom built t3 t2000 12" sub. Has the hp500 black coil. Sundown soft parts with megaroll surround. I have been hearing good things about aeroport boxes..but can't find any specs online. Anyone have a input?
  5. Dual SA-15 Box advice

    Hi guys, not sure if anyone can help. I have past enclosure building experience just unsure on a few things. Most of the boxes I have been are for 12's which in theory is the same but smaller right? I've decided I'm going with a 2x sa-15 rev3 setup. Which will be ran on 1500watts (sae-1500d). Im unsure on a volume but im guessing around 7-7.5 ft^3 on the power I will be giving them? Most of my boxes have been tuned to 33hz, But ideally I want to drop my usual to around 30hz. In regards to port. Aero or slot? Any benefits over one and other? I've always used slot's as their easier to work out area etc. I do like the inside flared aero ports though. If there isn't really a gain in my sort of setup ideally a middle slot port would be fine. In regards to the space I have, W40" x H35" x D50" (I have got more room than that but those are my preferred boundaries. Box will be built out of birch ply. Corners will be 45 degreed. Port flared. Corners flared etc. Also will be using threaded rod as brace's. (Which ways best to brace a box, Was thinking width ways? All helps appreciated.
  6. Here we go with another build. This one won't be as slow as the Chevy TB and I'm excited for that. This vehicle is my work car so I work on it profusely week after week. I am hoping to get this one done by end month so until then here are my plans. If what you see sounds familiar it probably is, but I won't tell...🤔 Thanks everyone prematurely for the comments and hope to have some good reviews from this build.

  7. Hello, Im looking to get a box design for 2 NVX VCW 12s from specs it says they like lower tuning and around 1.5 to 1.85 cubes per sub. with that in mind id like to tune to 30/32hz also i have good electrical that never dips below 13.5, i will get at least rated 2k if not more my max room is 15.5" tall,34"wide,23" deep thanks!
  8. I recently picked up a Orion hcca 15, it a d4 and it's going between the seats of my Dodge ram 1500 reg cab and I'm needing help with a box. I'm running it on a shark 3500.1 at 2ohms. I have big 3 and 2 optima batteries. The space I'm working with is 17.5w x 38L x 15H. I'm not sure if it will be better sealed or ported in such a small space. I had a sundown zv3 in 3.5 tuned to 31hz using a 6" port in the same spot and it slammed. Any help would be greatly appreciated, thanks.

  10. So just to state this is not a VS thread. I just want to know what the advantages or disadvantages of say running 2 12s that are 1k rms ea over say a single 12 at 2k rms or even a single 15 at 2k rms
  11. Hello, I want to run 2 PSI platform 1 12s on 2k, my voltage does not dip below 12.8 so i will be getting right around rated. I have a screenshot to show the upgrades, Biggest box i can fit is 34"wide 15" tall and 23" in length I would like for the box to be tuned so i can play slowed bass songs about as low as 26hz if the small space i have will allow it I would like a slot port design with the subs and port on the same side (center port) Thanks for looking and hopefully you can help me out! -Mike-
  12. So Its upgrade time and I plan on running 2 ascendant audio chaos 12s out of a trunk with the trunk being sealed, i would like to have the subs firing the same side as the port into the cab with the port centered between subs. Im looking for something with 4 cubes not including the displacements. tuned to 32 hz with 64" of port area and a 1.5" baffle i plan on using 1/2" allthread for bracing so it wont be an issue in taking up air space. Ive come up with a few designs but they dont work out, i need the box to be 34" wide with the height being 15" the depth cannot be greater than 26" thanks for the help!!! Also will be running on rated power
  13. Sundown zv4 15 box

    I need a box for my sundown zv4 15 rev1. Ive got it on a hifonics 1800.1 at 1 ohm. It slams right now in its current box but It sounds like the box is tuned to 35 or 36 hz. I want to build a 30hz or a low slamming box. Im new to building boxes but I work for a cabinet company so am pretty good with wood work and measurements and I have the tools so I thought I would give it a shot. What would be a good low hitting box tuned to 28-30hz for the zv4 15. I also want to know what program is good for tuning and sizing your boxes. I drive a mercury grand marquis so space isn't really an issue. Could someone design me a box for this thing that would slam 28-30hz? Any other ideas?
  14. I've seen quite a few write-ups on 4th order ratios and what not, but am struggling to find anything on 6th orders. what would a 1:1 compared to a 2:1, 3:1, etc. ratio 6th order sound like? Thanks!

  16. I am working on a new design for a build and I am in need of some math assistance. I have attached a picture of my design with measurements, I need to find out how much space is inside the box, it will be built with 3/4" MDF. Any help is appreciated, thanks.
  17. Looking to build ported enclosure for 2 skar audio ddx 15 dual 4 ohm on an rp 1500.1. Looking for subs up port back. Available space is H=22 W=44.5 D=22 trying to get between 34-36 Htz. Any design help would be greatly appreciated ive been trying to figure out something and my brain is just not working lol
  18. The purpose of this thread is to post your measured impedance plots (or values) for discussion. There are competitors that may not be inclined to share their data, but I still hope some experienced people will chime in. Its not called box rise, its called impedance rise, and there's a reason for it. Impedance rise is affected by the final impedance you're wired to, the characteristics of your enclosure, and perhaps some other factors. So it cannot be completely contributed to the enclosure alone. This is a really busy subforum so I was apprehensive to start this thread here, but since the primary constituents are subs and enclosures, this is where the discussion belongs. Hopefully we get enough traffic to get it stickied, since there's a lot to learn from even a single impedance plot.
  19. https://ibb.co/dxXUJF 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.
  20. Hi, I have ordered 2 sundown e-10's an amp, wiring kit, and everything else I'll need. It should arrive by thursday or friday. This is my first system, but I realized that I'm going to need a custom enclosure because just about none of the dual pre-fab 10 enclosures fit in the space I want. So i've gotten the measurements figured out, and how much volume I'll need, including displacement of speakers and my center brace. I'm going to be building the box tomorrow it's dimensions are 22.5 x 14 x 18 using 3/4" mdf. now that ends up being 2.06776 cubic feet of volume after a double thick (1.5 inches) center wall brace completely sealing each side from the other, and the speaker displacement is all figured in. so this is where i run into trouble i need to have 16"^2 port area, and have each side ported and tuned to 32hz and according to the volume calculator for rectangular enclosures and the slot port calculator on the12volt.com for a port that is 2inches by 8inches in a box w/ 2.06776 cubic feet of space i need a 17 inch port length, and if that's the case i can't put the port on the front because the subs will be in the way due to the width of the box being as narrow as it is, so i have to put them on either the back or the sides, but i don't have 17 inches of length across the back for each side. so is the 16"^2 of port area super necessary or should i try to make the box a little deeper, and then add some filling material (to compensate for the extra volume) and port it out of the back? i don't know that i can port it out of the back as is because again the box being as narrow as it is, and not being so deep, 18 inches depth and a 17 inch long port that is 2 inches wide wouldn't fit because the sub would be in the way. now maybe there is a super simple solution as far as design goes that i don't know about or havent figured out. but i'd greatly appreciate somebody's insight with some experience maybe i need to think up a different design for the box, or maybe not go with a slot port, i just really would like to get this figured out tonight so i can build my box tomorrow. any help or comments will be greatly appreciated. My maximum dimensions are 22.5"W x 15"H x 24" Depth Thanks for taking the time to read and respond!
  21. I am planning on building a sub box for a RX8, but since the trunk is small, my options are limited. I might use either a single Rockford Fosgate P3 - 10" or 12". But I've heard about 'port noise' and was wondering if my design would make the noise I am using 5/8 MDF The dimensions are in the pic:
  22. From Torres to CAD

    So I'm very unhappy with my current box. I have designed one that I think will sound much better. I am wondering if there is someone that would be able to bring my design to life. I use torres but would like a visual of how it will go together and what my port cuts should be. I don't have a CAD program that will allow me to do that. I'm open to any suggestions as well. This box will be built for an Fi Bl12 V3 on 1500w. It was suggested to me to shoot for 30sqft of port area. Thanks in advance to anyone willing to help me out.
  23. When getting a box is it more important to get the correct tuning or the correct size? either 32 hz but .25 too big or just right size but 37 hz, sub requests 32.
  24. I recently got a hold of an old L5 and was wondering if anyone had any experience with building a box for them because in the manual it gives a fairly wide range for enclosure sizes, so if anyone has any idea what a good size box would be to start with that would be great. Also haven't decided if i wanna go with a sealed or ported box yet so might build one of each and try them out. Just let me know what has worked for you or what u have heard works and ill go from there, and will someone send me the link for the torres box calculator i got a new computer and haven't downloaded it yet. Thanks for the help
  25. 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
