SPL & SQ / Fabrication

I have talked with rob and rusty from dc on everything to do with my upcoming design for summer 2012. I am going to go with 2 xl 12s on two SAZ-3500Ds, backed up with juicebox batteries and a 220amp excessive amperage alt. The box will be a little smaller than recommended seeing as DCs love smaller boxes when they are overpowered. Now my question for everybody that I cant seem to get a hold of is port area, would I be better off giving it a little more (Kerf port btw) space (say 18-20sqin per cuft) or the "normal" range of 15-18sqiin per cuft? My goal is to get decent numbers in the low 30s. I do not have the depth either for aeroports. A 5" aero though would be 21 sqin p…

Just a for instance: Say you have an enclosure 40" wide x 32" long x 30" high, The port is 38.5" wide (facing forward), 6.5" in height, and 24.5" in length - tuned to approximately 34Hz (I'm assuming a driver XMax of 20mm.) The Net enclosure volume is 14.40 cubes, less driver displacement. You have the option of placing (4) 15" subs on the top baffle, or (9) 10" subs. Which do YOU choose, and why? What subs would YOU do? Roughly 1.5 cubes each for the 10's, or 3.37 for the 15's. Either way, it would be possible to run whatever amp at 1 ohm Mono - Strapped SAZ3500's, anyone? I'd be VERY interested to see/hear/speculate what the XCONS would do......

I was wondering if I could use metal L brackets in the inside or outside the sub box the reduce the vibration or flex? I saw the wood ones, but those take space inside the box and my box is quite small and I don't wanted any more smaller.

if your going see you there,,,cars still not ready but im taking it out anyway

Stupidly I bought an 18 Fi BL and didn't realize I couldn't fit the recommended box inside my trunk...its anywhere between 4-4.5 cubic ft..Is there anyway I can build a new box similar in size that will increase the current SPL levels and help not suffocate the sub-woofer so much?

Ok so i have decided to build a box with aero port but im a little lost with the tuning the box will be 6.5 cubes with a fi btl 18 in it if i use two 6" aeros how long do they need to be to get too 33 hz ? thanks for the help guys =)

Ok I owed a freind of mine some money so he asked for a box and retarded me i said ya lol so here we go. It will be a bit different decieded for free i might as well do something different try something new. 1 cvr 10 1.8cubes tunned to 36hrz with an external port 28sqin.. design will be up in a bit and box will be bedlined

Next weekend I will be starting a new box build and was hoping to get some help from yall on an enclosure design. I could probably do what I did last time, just use RE calc and Google Sketch to design. However, I hear too often that the RE calc is not very accurate and tuning can be very off. I want to build this box to last me a while, so I'd like to do it right the first time. - Subwoofers being used are 2 AudioQue SDC2.5 15" - Power will provided from a SAE-1200Dv2 @ 1ohm - I'm not the best wood worker, but i can get a simple box built. I've done one already. I have a Jigsaw to do the cutting. Not the best, but it works. - I will buy MDF from Lowes. - Build will be for…

Finally designed my first enclosure. It is for a 12" GCON. ~2.5 ft^3 tuned to ~33hz. Does my math/design look correct? Does this look like a design that will translate into the real world effectively? It will be going in the trunk of a 1996 Honda Accord sedan powered by an AQ1200. This is what I came up with to fit my trunk space needs. Any critiques and opinions are welcome and greatly appreciated.

I am looking for a good place to go to learn about building crossovers. Not only how but what components to look for, theory on how different setups affect sound, anythng and everythng.

I am trying to find out how many cubic feet i would need for 6 SA-15s in a ported wall It will be ran by 2 2600w soundstream amps and I willl be playing rap and bass tracks.

I need help with an enclosure I'm building my enclosure is 2.51 cuft after displacement it will hold one fi Bl 12 ran off a T1000 amp I would like to tune it to 32 HRZ with what info I have come up with in order to tune it to 32 HRZ if I go with a 4"port 10.3" long it should be around 32HRz does this sound right my enclosure is 16" deep 54" long 9.5" tall in the front and 7.25" tall in the back it will be up fire and I would like to run the port off the front witch is the side that is 9.5" I'm working with very little room so I can not change the die mentions of the enclosure much if you have any suggestions on how to do this right please let me no add if …

Hey all.Im going to be getting a different enclosure and im wondering how big it needs/should be.I have 4 10" DC lvl 3 subs with lvl 4 upgrades.Ive been doing some thinking and I think i can move my batteries and have room for a bigger enclosure.The max deminsions I could use would be 32W x 19H x 40D.My goal is to hit 150db and I just cant do that with my current enclosure.I know the deminsion I gave are probaly to big for the 4 10's so thats why I was wondering how big I should make it.I would like the entire enclosure to be double baffled and I would like to use aero ports.I have always liked aero ports but I have never had a enclosure with them.I would like the enclosu…

We are having a meca sponsered show, and should be a blast , there was about 50 cars here last time, and everyone had a blast. if you have any questions feel free to call us at 269-426-0009 ask for kyle here is the link to the flyer for the show. http://www.mecacaraudio.com/flyers/5-20-07MIv2.pdf

i want to wall my lincoln but first i need to make sure i wont get a ticket if i do have a wall. any one who knows about that kind of stuff any help would be good.thanks in advance

I have been searching around now for a good 30 minutes on how to figure out the bass in a song. I know you use some program and play the song through it. You then select a little bit of the audio stream and analyze it somehow and it will show how low the bass gets... (I am trying to figure out the bass line in song. When it drops to the second lowest, I have never heard my car rattle so much nor my woofer get so loud. The first bass "hit" is at 34.5 seconds. And the bass hit at 37.5 seconds I need to filter out. I see the speaker move for it but cant hear anything)

Hi, i have 2 offers for subs one is for 1 mt 15" quad .7 for about 300-325 and the other is for some 10" xsite D4 which i was thinking to get bout 6-8 for 28 ea. so...which should i get?? i want spl btw i dont care much bout sq... edit: i have a SAZ-1500d and planning on getting a 2nd one

So Lowes is having a sale in my area and i noticed that 3/4 MDF 4x8 sheets are on sale for 32$ I was wondering, how many 4x8 sheets would i need to make a 4.0cf ported box After displacements. Any help is appreciated. Oh and theyre having a sale on 1/0 for 1.93$ a ft

hi every have another question my step dad bought me another sa-12 as a late xmas gift and he gonna help me build a new box for my 2nd 12 gets here but the space i have is 39x16x22 1/2 which is w x d x h. now my question is is it possible to build a box for these two subs with this much space ? and how high do you think i could tune the sub's at as well if it's not i can add more height to the box.

Hey guys..I haven't completely started building anything just yet and this will be my first build and was just wondering about the port type and location of it and the subs. I don't have any exact dimensions or anything just yet just need to get a simple idea first. I have 2 T12's (rockford) in a prefab box now and wanted to make an good box for them. Any idea's on port type, sub and port location would be appreciated. And any first time building tips! I've heard a lot about subs up and port back but not sure if anything else would sound better in a hatchback. Thank for the help in advance, Ted

my question is im trying to make a box for 2 18" btls dimentions are 49"L x 24"T x 27"D here are some rough sketches from paint how should i go about bracing it i know that i need to(or do i?) since im planing on running them on 2 SAZ-3000D and i will doublebaffle the top where the speakers will be mounted would simply corner bracing like in this pic be enuff and also placing a small block of mdf on 1 or both sides of the port to support the middle of the box

I just got a 12" Mag from Low-Hz, and currently have it in my old sealed box that housed a JL 12w6(v1). That box has about 0.8 cubic ft. after driver displacement. Anyway, I was planning on building a ported box and got this off the net: http://www.subwoofertools.com/forum/ported...=&Vas=&Fs=&CE=0 I was all set on building it, but decided to read more, and the more I read, the more I get confused and hesitant. So I decided to ask the official SI site for input. I want the best ported box with a maximum width of 30" and max height of 13". It's going into a 95 Ford Mustang, and I would like the box to fit perfectly into the hole when you fold down the seats. …

Its been a while since ive been on here... but i need some help... I'm building an enclosure for my new car (02' focus ZTS) which will house 4 10" woofers firing towards the rear of the car at a slight angle with the deck lid.. (ie 35-45*) question one... is this going to cause a lot of cancelation? question two... i want to build a seperate air chamber to fit the spare tire well... and connect the two chambers to increase my overall air space... will doing that actually do anything for my airspace considering for now... the box is sealed? thanks for any help -AcId-

I want to put 3 batterys in the back end of the car. I have a lot of 1/0 wire. Which is better/correct?
