SPL & SQ / Fabrication

Just spent the past hour trying to understand the entire deal with box specs and this is what I got Didn't really do any displacement math which is why I put in the Tuning Freq. at 26 Figured after all displacements highest it'd be would be at highest around 35 Hz Anyone see any design flaws with this? The Box is going in a 2002 Jeep Grand Cherokee Laredo and I listen to Rock/Rap but more so Rap music.

I will be building some custom tweeter pods for my new Morel tweeters that are coming, I was wondering if someone with a lot of experience can tell me some of the better directions to aim them. I'm looking for good staging, and good response. Any help will be much appreciated.

Hello all. I was hoping to get some advice from the SSA community. I have a 2009 Sierra Ext Cab. Currently for substage i am running a 18" Zcon and AQ2200d. The box is 6.6cu ft. net @ 28hz. with 112sq in port area. Sub is firing forward behind drivers seat, port is up. The whole truck has been deadened other than the roof (not too much flex). Pics can be seen im my build thread. Since the pics i have added the AQ2200d and changed the tuning from 34hz to 28hz with a port extension. (the port now fires up from the top front instead of the top back) Changing the tuning really helped with my lows but its still not quite where i want it to be volume wise. Some songs that slamm…

I have a 2004 Cadillac SLS and am looking to fab a 4th order enclosure for 2 SA-8 V.2's on a SAZ 1500 V.3. The reason for the smaller sub is to help save room in the trunk and to still have high output. The reason for the 4th order is the infamous Cadillac trunk bass trap, so I would like to port the enclosure through the stock sub location in my rear deck. I am not too familiar with hertz levels or anything, but I can tell you that I listen to every thing from Hip Hop, R&B, Jazz, and Alternative. New to the forum here and just looking for some experienced suggestions. If you would like more detail please let me know. Would like a little seasoned input before I spend …

I have a 95 Cadillac deville with trunk measurements of 47x23x17.5 I trying to figure out the best box for 4 dual 1 aa mayhems if anybody has any good feedback would help out a lot

Would this be a good box for 2 xcon 12s running a crescendo bc 2000d I'm planning on running it at 2 ohms because I'm hoping to run stock alt with an extra batt. in the rear for now. I was hoping to run sub and port forward sealed from the trunk so my max height is 18 and width is 32 and that's real tight. If someone else has done this I would love to see pics for reference. http://i1257.photobucket.com/albums/ii511/trpkkd/accordbox.png

I need some tips on doing a bed cut. This guy has 3 digital design 1500 12s. I cant remember the year or model but its a dodge single cab. The diminsions i got were 15" tall, 40" wide, and around 40" deep. He has them on a kicker zx 1000.1. I just need some tips on how i should go about doing this, since i have never done one before.

I am working on an intrepid. I am building a new box from the ground up to compliment the rear deck that i am fabricating with fiber. I would like to build a box to be able to port up through the deck and blow into the car. I will be using 2 12" ICONS. I have never designed a complex box before, so this is what I ask. What would be the best way to fire the subs, what should i do with the inside of this box, and HOW should i fire it up into the car? Any help would be appreciated, keep in mind that I am a box newbie. Patrick

A buddy of mine wants me to build him a subwoofer box for two 12's in his Ford Ranger Edge. Now he is taking out all of his rear seats which gives me a good chunk of space to work with. I know how to build and design an enclosure, all i really need to know is subwoofer/port orientation. Havent made an enclosure for a truck like this and I dont have the time to build multiple enclosures and test them all out so I was hoping this could save me some time. -Mike

Ok, I tried to do some research about tuning and port area, so I didn't have to make a thread. I read a thread on smd and they were saying 10sqin per cube was better for low tuning and then others were saying other things like more the better so I don't know which is right. A lot of misleading information out there!! Much rather ask here and know I'm getting the right answer lol I'm most likely going to be ask pro-rabbit for a design once I am sure of my measurements,It'd be nice to know exactly what it should be, so I can expand my knowledge. I would like to know for my system specifically, but also in general. EQUIPMENT: Subs: 2 SSA Zcon 12s Amp: 2 Crescendo BC2000s(won…

i have a dcon 12 in a sealed box Internal box volume: 1.2 cubic ft Box Dimensions: 14-1/4"L x 14-1/4"D x 14-1/4" H Its amp is an mbquart 400w rms in a chevy 1994 blazer. it goes pretty hard but from what iv heard, it can go louder with a bigger box and a ported box. its facing the back of my car. Could i get some help on how big to build it / all of that kind of stuff? like dimensions, volume, ported size. i might take it to a local audio shop and have them build one but i don't know what sizes and stuff.

2 SA12s, ported to about 30-33hz, whatever you think is best. I would like two seperate optimal boxes to go in the back of a Dodge Charger, with 1200rms. Im looking for decent SQ (at least at low volumes) but mainly SPL

Im in need for ideas for I my 1975 El co. I just purchase a 12" Zcon was planning on putting it behind my seat. i would like it tuned about 32hrtz with a kerfed port. My spacing is 18Dx7.5(small side for drive shaft.)15Hx30W. im going to cut out the the metal to get my depth and with if needed. Im gonna be using nendo bc2200. I will b using the car as a cruiser but if i need to turn it up and put the kids to sleep at car shows i want that loud and low sounds. I listen to new and old school rap but mainly R&B hip hop is my style. I want the sopund that people in my area are saying impossible for my ride. Please Advise.

Has anyone put a xcon in a 4th order? If so how did it sound will the sq be just ass good?

I want to go with a 4" aero for this temporary build. I am going to go 24x13x13 with 4" aero at 14.5/8ths long. Tuning will be around 35hz? Volume should be 1.5ish after displacement?

i wanna use a 6 inch port tube going up in my car from top of box and sub facing back cup holder whole in seat.I no wat size is optimal for the 10 xcon. But how long would the port have to be. I want to tune around 30. My space to use up (32L) (14H) (14D)

Hi, just wanted to ask which box would be best for my space and will do the Best Output, I want a box it with a maximum of 4 cubic int. feet. I am going to buy 2 12'' SSA Xcon and I will like to know which type of box (Ported or Sealed) is best recommended for my space and my needs... Thank you.

Ported SA does this make sense? Hey guys iv been searching back and forth between forums to calculate my box as close as possible. Before I spend more time and most importantly money on my design I'd like to know if I'm on the right track. Any help would be greatly appreciated Box width - 24 Box height -11 Depth 1- 8 Depth 2- 8.5 Total Net - .835 Port measurements Height - 3 Width- 3.5 Length - 29.64 Now when i put that port in the calculator it says my total net will be .653 the sa 8 calls for .5-.75 ported so I guess I'm right in the middle the other forum I used says that port will have the boxs original net volume of .641 ft3 tuned to 36 hertz Does this seem to be co…

do yall think 2 cf sealed and about 4.5 cf ported befor sub and port displacement,15" zcon, and how to i figure out how long to make the port, port is probley going to be 6" by 9"

So I decided to go with 2 12" Zcons D2s and I just wanted to see how well I did my box. I'm trying to learn how to design boxes better and wanted you guys to check it out. I want to have it in a ported box with port and subs front firing sealed off from the trunk of my 2012 Fusion. It will also have internal bracing with 45s. I have 2 Crescendo Bc2k and will have a H/O alt with a xs d3100 in the back. I want to have the port in the middle but I'm stuck with either doing a slot or aero port. The slot doesnt allow me to get as much room as the aero does obviously and also the aero allows me to tune lower. I would like to tune around 32 hz. Does that sound good for the zcon?…

Cabin volume vs box volume. when building a wall do think the box should have more volume than the cabin? Spl should be louder in the smaller of the 2 right.

guess i am looking to do a 1.5 tuned to 34 hz with the sub pointing up. I have a 4" aero port that i would like to use. i would like to keep the depth at about 15" if possible. any help would be great.

Im trying to make a box for a single 12" dcon can you guys give me your feedback and let me know what you think please? im new in building boxes this is my first and looking for it to be tuned at 32hz demensions for the box are as seen in the calculator( long story on why i chose those measurements and dont want to even explain why) let me know what you guys think please and also for my port according to this what would be the sizes of the 2 pieces of wood i would cut for it? thats only thing im confused about at this point.

I have a DC XL m1 18 that i am wanting to put in my truck (02 Silverado 1500HD). I am thinking about taking the 60 part of my 60/40 back seat and making a box above my amp rack. I am wanting to tune to 30 hz or lower and would like to possibly do a hairtrick. Is it possible to do in my truck with a single 18? Here is what I have right now: 1 DC XL m1 18 D2 1 Crescendo BC2000D 1 Mechman 270 amp alternator 1 Stinger SPP1500D battery under the hood All 1/0 for big 3 and running to amp This is a box I come up with Would I need more port? Should I change anything else? And where should I place the port? the sub will either be facing up or forward. Should the port face forward…
