SPL & SQ / Fabrication

When using a PR in place of a port, you would keep the same internal box volume as the equivalent ported enclosure, correct?

Im needing help i only have a phone no computer and I'm wanting a box built for my new soundquebd hds3 12's i got two subs and my dimensions are 30" deep 35"widr and 18"tall wanting it tuned low around 31-30hz I'm also wanting subs on top facing the roof and port facing the back hatch I'm using a 1200.1 super d class mono Zeus amp with big 3 upgrade and 0 gauge wires but I'm unable to access these sketch up things and box calculators so can someone please help a fellow bass head out and please send me a blueprint of this and a cut list of sides and port and everything pretty please b greatly appreciated

I've been reading the Loudspeaker Design Cookbook and found the effects of lobing due to driver placement on the baffle, but am still left wondering two things. Use the picture below as a reference to how the placement would differ. Assume same port length and volume for each. #1: The port ends in a different location inside the box, does this have different loading effects on the sub? From appearance, it would seem that the air flow in each would be somewhat different and affect the subwoofer? #2: What happens to the subwoofer and response as you move it closer or farther away from the port? Is it best to have it centered or off to a particular side?

I was wondering if anyone could help on a the best way to approach walling my truck off I have 2 18" zcons facing forward and the port forward and I want to wall it off I was thinking getting cardboard and getting the outline of the rest of the space that I need sealed off and putting it on some mdf and cutting it out but I can't think of how I would attach that piece to my box without wood gluing it so if anyone could help ibwould appreciate it

I have been messing around with SketchUp to design a box for my 15 Xcon, I have only built a few boxes all of which I used the re box calculator so this is new for me. I'm looking for any suggestions or recommended changes to what i have so far, as far as port area and tuning frequency. This is based off an estimated max size 34"w 17" h 18" d. (I'm going to make a test cardboard box to see the largest size that can fit through the opening)

I am new to this and replacing my RE SXX 15 worried after a year it sounded cool, but the thing on E40 etc. to long might have to be turned down got a little smell. I have looked at Xcon wanting something lower and only way I could fit an 18" would be in a sealed box, upgrading to try and get more low end, handle Hifonics Brutus 2400 better, and hit all day. It will be one speaker guess everyone seems to call Xcon SQ sub more than Zcon, 15 would bolt in box net slightly over 3.55 aero port 6" might upsize box and run 4-5 4" tune it lower even in current setup probably tune it lower then RE was. I looked at the Zcon 15 because of the better coil and actually sensitivit…

I found measurements for an enclosure for my 2 12 inch pioneer champ pros tsw3002d4. The box is tuned to 33 hz. I was just curious as to whether that would be good for my subs or too low? The amp I am using is a hifionics zeus 3000 watt zrx3000.1d. This will be my first box build so I want to be as clear as possible. I used RE audio calculator if that is any good.

I'm just looking for some pointers on where I could look for reputable information on designing 2 way passive, 2 way active and (after some practice) eventually 3 way active front stages. Just stuff like, what to keep in mind as far as driver selection, particular features to look for when choosing a certain driver, and how to design passive crossovers. I was daydreaming and hit a roadblock when I realized, what the hell do I even know about a quality front stage? I can't say much at all, other than, deaden, and airseal the speakers. So I feel like it's time to start learning, might even have some applicable tips on hand for when the new truck is ready I'm plannin…

I am looking at some new midbass drivers and it looks that they should be ported. So if and when I build this enclosure in/on my door is there a recommendation on where to point the port in this application? thanks in advance.

Hello All, I am currently in search for a really good Mid-Bass Driver. My budget is around 200$ per, it "could" be stretched a little higher if needed. I currently am a competitor for the SPL side of things, but for this upcoming season, I am also wanting to compete in SQ. I am not wanting to become a world champion per-say, but I would like to earn a respectable score. Yes I do understand how judgmental SQ can be, as it's all person preference, as well as a judge to judge scoring. For this portion of my audio system, I would like to ignore my SPL installation, and to strictly concentrate on the SQ aspect. I am currently and will like to continually run an 2 way acti…

I am using a audiocontrol 3055 to tune my system once its parts arrive. I like the kicker KQ30 but it has 1 in and 1 out for RCA. this would make me think i need to have amps with pass through. if i am outputting a 0.2V signal from my HU to my KQ30 and a 8V out of the KQ to amp 1, 2, 3, 4, and 5 would amp 5 have a 2V signal or a 8V signal? how many amps can i daisy chain in this manor before i run into issues. secondly i have a KX3 that i do not believe i will need but if i end up using it would i run into a SQ issue having HU > EQ > Xover > amp? would that added processor cause issues with sound quality? a third question is if i am to have all my amps/proces…

I'm thinking about building a new box for my 15" DC level 3. My current box is slot ported to the back with the sub firing up towards the trunk lid, 3.3^ft tuned to 32 hz. I was thinking about building a box firing into the cab (BMW 330CI). Im not too experienced with building boxes but think i can manage this. Has anyone here done this kind of box before and can give me any pointers?

Long story short my friend built my box and it turned out horrible it wasent his fault he did not have enough tools or supplies but I'm getting a shop to build me a new one and I have an original design but its to wide but I can add to the height my dimensions are 22 deep 33 high 55 wide the box design is 27 high 27 deep and 54 wide wouldn't the volume even out if I went 32 high and 22 deep?

So I am designing a new enclosure and this one will have a center port. I have concerns with my port width when it reaches the rear of the enclosure. This is for 2-Zcon 12's,SAZ3500 power,currently box will be at a net volume roughly 7.8 cubes tuned at 32 the distance from the port wall to the flare is 4.33 inches if you cant read the photo Since it is in the center do I need to maintain the same width(in my case 6.5inches)? Is there a rule of thumb for this? Here is a pic of what I currently have designed.

Looking for someone to help me design an enclosure with a kerfed port. I have been trying out doing it on scrap wood in my garage for a while and wanting to try it out on one of my enclosures. I have someone wanting an enclosure built right now and figured it would be a good one to start with. Its for 2 sundown sa8v2's in a trunk . I was told there Going to be on 1-1500 rms. . .Max dimensions - 30 wide 10 tall and 16 deep. (Ill ask if any of the dimensions can get bigger) Wanting it subs facing up and port back. Tuned in the low 30s. 30-34. . . . . Listens to mostly rap music.

Does anyone know what the tuning is of the dual X15 box sundown recomends? And how many cubic ft it is?

Have a 12" icon showing up soon and would like to get an enclosure ready for it. I've been using the bitpusher site to help me calculate the box. This is what I have so far Now I prefer to use a Single 4" precision port. I'm unsure how to calculate the entire port area I have with this setup. Reading through past threads and SSA's recommended 2.25 cu ft tuned in the low 30s. Also saw in a thread that for that size box I should aim for around 35 sq in of port. Pi * r * r doesn't calculate the length? Missing something somewhere maybe someone can help. Is a single 4" aero going to give me enough port area? Anything you see wrong here? One other thing. Going off the picture…

I have been messing around with WINISD for the past day or so. Trying to model my 12" Zcons and follow what these graphs are telling me. 1. When I enter the parameters using the autofill for some of them my graph peaks at around 100hz even though my box tuning is much lower. Why is this?Can someone help this NEWB to understand what I have done in error. 2. Also if I enter the paramters of the web site it gives me error messages saying they are incorrect. If I let it autofill some of them then it will graph. Any explanantion why this is? Thanks in advance.

So I've modeled my Crystal cmpx2 12" and it is completely flat from 30Hz + in a 2.1 cubic foot box tuned to 22.8 Hz. That's perfect but I'm having a hell of a time putting it together. I have my max dimensions but I'm stuck. It's a slanted box in the back. Can someone put something together so that I can get this built asap? Height can definitely go down, and width can definitely be made smaller, but I'd rather it be wide over tall just to look symmetrical. I dunno why but I'm insanely anal about symmetry. 40"w x 18" tall x (9 1/4" d1 /// 14" d2)

I built a sealed box for my 12" ICON to proper size for my mustang, but I've recently sold that car and picked up a small hatchback. I want to stick with the sealed enclosure design for this car to minimize the amount of space. Whats the smallest I could go enclosure-wise for the ICON? Would it be possible to go smaller than the .9-1.25cu ft size thats recommended if the difference way made up with polyfill? Ideally i want as small as box as possible but I still want the sub to sound great.

i have a 96 sonoma king cab i need help designing a ported box tuned in the 30s to kill lows if some one could help i just need a blue print to biuld off of

Hey all. I've been riding with the ICON sealed for some time and want to put it in a ported box. Really not sure how to make sure the design is correct or even how to work WinISD but below is what I've gathered. I was posting on diymobile and got some help and was suggested a ported box, 2.0ft^3 @ 30hz will give the flattest response. Below is a copy paste from the sticky of "making a correct box design thread" Vehicle : 08 Acura TL Location in the vehicle: Trunk Space available (Length x Width x Height): 23x19x14 (Can be wider and deeper than height) Subwoofer make and model: SSA ICON Subwoofer Size: 12" Number of Subwoofers: 1 Type of Port (Kerfed, Slot, Aero, etc.…

As I begin my adventure in the SQ lanes, I have been doing a lot of research and studying. My general synopsis is, for SPL, in a vehicle, we want the most reflective material possible, such a concrete, or marble, so that there is no loss in energy. Obviously this is not practical, but in this example, it will work. Ok, and for SQ, we want the total opposite, we want complete absorption so that none of the higher frequencies reflect, which can cause interference, overlap, and many other issues. From what I've seen, things such as egg carts, foam, or MLV would be the fix. So what I am asking, what would be the best and most particle material to use in the vehicle for sou…

My 12" ICON is coming in the mail today so I want to finalize a design before before having my buddy build it for me. What I want to know is if I have calculated everything correctly and will in fact end up with 2.3ft^3 at 32.5hz. Here's how I measured the port length. 19.2140 + 14.8723 + 1.375 = 35.312 The the12volt calculator says that this length gives me about 32.5hz. Did I design this correctly? Also, I just used the displacement listed on the product page which is .16. Does doing a double baffle affect this? Click here if you want to download my SketchUp design
