SPL & SQ / Fabrication

okay these dimenions that i have for this sub box say the front and the top are the same okay thats where i get confused with it because i thought the top was the top of the sub box and the front where the ports at is the front not the other way around. 2cubes35hz2925sqin6tn.png i hope that the picture worked because i do not know how to put them on here if it doesn't work just tell me. because this is really confusing me really really bad.....

ok ill give a quick run down of what i would like to do.. i would like to build an upside down L box.. with the slot port going into my cabin.. and my subs on the long part of the L inverted. to save space and show off motor... here is a pic of my trunk. the top part is is 10 tall... 19 deep and 41 wide. from the floor to the step level is 14 and from the floor to the top lip is 26 and i want to port thru the rear deck ill cut this all away i know its kinda hard to picture what im talkin about... ill come up with some sketches of what i would like.. but im wondering WILL IT WORK!!> i need some where around 3 cubes and tuned to 30htz thanks guys, ps. not…

We will be finishing up on my son's car soon and I have been wanting to wall-up my ride for a while now. I have a '93 T-Bird and I really have no need for the back seat. I have thought about a newer vehicle, but the old bird runs and drives great and I work very close to home. I allready have a pair of Saz-2000 amps and 150' of 1/0 welding cable. I am deciding as I write this about the SA-15 Presale. My thoughts about the wall are as follows: From a rough measurement I have 31-31.5" height 42" width 22-23" depth These measurements should give around 14.75cu' gross I would like a slot port centered with a measurement of about 29.5" high and a width of 6" thats 177" at alm…

Whats up guys, I'm kinda a noob here but I've been lurking around these forums for awhile trying to learn as much as I can before I start this project. I'm mainly here right now to talk about the box. I'm planning on building one myself and the specs are going to be 3.8cu ft tuned to 31Hz. I used a box calculator from a site called KlausAudio.com and I was going to see what you guys thought, because I've heard these online calculators can be off sometimes. Here is a list of the dimensions of the panels needed. The sub will obviously be a Fi Q15(Dual 2 ohm) and I'm planning on running it on a AQ1200D amp. And my car is a 2002 Camry. Just wanted to get some input from gu…

I'm looking into getting a new 10" sub, I have had a fiaudio btl and after that experience everything in my truck is loose. I am looking for the best bang for my buck in a sound quality sub, I have considered a fi Q, I have heard good things about sundown audio. Any suggestions?

Hi, I am getting ready to switch my system from my firebird to my truck, so I can sell the car.. It's going in a 99 s10 ext. cab xtreme.. I have 1 12" pioneer premier 3002d4, It's in a sealed box now, but I want to build a ported one for it. I will be using a precision power 1500 amp at 2 ohms, so roughly 1000 watts to it. I know how to do the wood work, but I am not near as good with calculations.lol. A good slot port box design wood help a lot, if anyone has the time. I would like it to be tuned to 34hz, with 1.7 cu without the sub. For room in the back of the truck I have 14 1/2"x18 1/2"x50".. I know thats more than enough, but thats the total space I have. Also, wh…

I have 2 Orion H2 12.2's to be powered by 2 Orion 2500d's and want to build an enclosure for them,the only problem is i'm not sure of the air space to run.I want to shoot for max spl,i was told 4 cubes per sub tuned @34 hz is prime but i'm not buying it.Any help would be appreciated,thanx!

Uh its me again this time instead of an extreme i need a box for a kicker comp 12inch 4 ohm sub that will be going in the back of my explorer i have tried my best with the messurements but i am new to this it is 38'' inches tall, 42'' inches wide, and 38 inches long it's not the best sub in the world so the demenions do not have to be perfect just a simple design would work for me........ just send me a message on here....... if you can.......

ive never done it before is it hard ive seen pics of people doing it but i dont really know what to do i think i need a video or tutorial i couldnt really find a good one most were for boxes i dont want to make a box and i need to know all what to buy the speakers are already mounted in my door i just want to cover up the ugly hole around it so just the speakers show

im looking to buy a single 15" sub. im upgrading from 2 12" sony xplod sub so im sure whatever i pick is going to be a helluva upgrade but i still want to get the best bang for my buck and SQ. I looking at the Icon X and Fi Q and i wanted to know which would be louder and have better SQ. Also what box should i use sealed or ported Vehicle: 2008 Trailblazer LT with bose all the way around with a pioneer 3200 DVD indash headunit. THanks for all your feedback

Ok i need some help.....i am doing a business and marketing plan(IMC) for a car audio company(mostly enclosures) and when i went to a nameless place(audio store here) i asked the guy what the difference is between ported and sealed box He said nothing....now i know there is a difference i just not sure the reasons...i need to be able to explain it in my presentation in november.. if you use acrynoms or intials(spl or rms) please tell me what they mean so i can use them. i am expected to know all about whatever i present.

I'm starting my first system with 4 of the rl-i8's and need a lil help on my box. it's not gonna be just one big box but 4 seperate ported boxes. each one will be about (acording to the program im using) 10" wide, 15" tall, and 9" deep. im having problems with the port though. the program said it should be 1/2" by 2" by 2" deep for a 35 hz. this sounds way small to me. is it? and does this idea seem good or is it too "over the top."

I'm running an Fi BL 15 on a sundown sae-1200d in a scion tc. Bought a prefab box for it a couple of months ago but im looking to get my system as loud as possible (currently upgrading electrical as well). The box seems to be tuned around maybe 50hz or so, as in Young jeezy's song "white girl" (i believe it has a 30hz note and a 50hz note) and the 50hz one hits way harder than the 30. If i built a new box, and tuned it to around 33hz, in that song it would be the other way around having the 30hz note be the louder one correct? Heres the box that I have now: http://img841.imageshack.us/img841/1833/img2746u.jpg How much would it cost roughly to build a new box like this (s…

hey guys, im purchasing 2 12" Fi ssd Im looking at a ported box, I was just wondering if i need the divider in the middle of the box giving them their own little chamber? or can i just make one bigger port rather than 2 smaller ones ? also aeroport? Is it worth the try ?

Hey all.I REALLY want to build my own box but im worried that it would be to hard to do.I would like a simple dual 15" ported box for my type r 15's.I just don't know if its something I can tackle or not.So my question is in your guys eyes on a scale of 1-10 1 being easy as pie 10 being hard as can be,how tough is it to build a ported box?Also is there like a site or something that can help me with a design and other stuff like that?Thanks

I know it may take some time specially being designed in mm (As I live in Aus) but can someone or as many people as possible confirm roughly these figures??? Also, feel free to use this design and enjoy!!! BOX HEIGHT IS 260mm, 224mm are Internal Dimensions as all pieces join to TOP/BOTTOM ------------ --------- Also I designed this for a 8" Rockford Fosgate P2D28 sub w/ a bit of extra port area for sub upgrades that may have up to 13mm in XMAX such as say a DD sub (P2D28 has 9.5mm)

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

I haven't had much experience with the science behind port tuning/building, but I've been doing a little research and some calculations and have a question concerning port "size". Let's say I have a 1 cu.ft box, and I want to put a aero port in it with a tuning of about 33hz. I used a calculator and I came up with a 2" diameter port with a length of 6.3 inches.. or a 3" port with a length of 15+ inches.. My question is, what's the difference in having the 2" short port as opposed to the 3" long port and achieving the same tuning? To me it would just seem logical to go with the small and short port to save space and material, and just be an overall convenience.. but this i…

I wanna know if I could build a 4th order bandpass box for 4 12" subs in the trunk of my cavalier? I have a Soundstream Rubicon 2500D amp and a Kinetic1200 under the hood and a 2400 in the trunk. Thought about something sort of like this but, not too sure it would work with being such a small trunk...Just need some help tryin to figure out if I should do it or not. http://sketchup.google.com/3dwarehouse/details?mid=5362d8048075cdd16b752e7529d36aed[/media]

Hey, this is what i got: 1x pioneer sub ts-w3002d4 @2ohms=1000rms QCA3500D amp; 2ohm=1750watts rms enclosure: 20"x16"x13" port size: 2"x11.5" everything on my car is stock and i think my amp is putting out a little less than what is rated performance wise, i dont think that my sub is performing like it should, my excursion is nothing compared to what I see on you tube and im not sure if it is because of my enclosure. I know that I can get better power if i upgrade wiring but I think I should be getting more out of what I already have. I want to try a different box, does anyone have any suggestions on sizez and I dont know much about tuning but im not getting high end …

what type box would you suggest for a sq setup i know the norm is sealed but i've heard a few ported boxes and they sound pretty nice give me some of the pros and cons of both btw subs being looked at are idqv2 12" IA LI 12" and SA-12 thanks for any heip provided

1 18" DC Level 5. Still waiting for some other bits to come in (amp/battery). But in the mean time, we want to go ahead and start on the box. We were thinking of these two options. 1) Sub up/ports up. Have sub in middle, with a port on each side of sub instead of a single port. Does anyone see any negatives to this besides using up more wood/cost more? etc... Basically would like to do it this way because OCD side is taking over, and we would like to keep it symmetrical. 2) Sub up/port back. This would just be sub up, with a single port along the bottom of the back of the enclosure. Pretty straight forward. Basically, just looking for yall's opinions. Which do you t…

they had it locked on to show just the highest db hit, so idk what i made on tones. my sweet spot is somewhere between 40-45hz but i hit 135.7 with my single 12" FI Q w/ BP Option, powered by SAE 1000D my first box, tuned to 31hz playing the opening of Tortilla Chips by T.Bizzy. mic on driver side dash, passenger door half down. in a 2001 Jeep Grand Cherokee. sub and port facing back hatch nothing fancy in here. i know when i bought it i was curious of some numbers, i know it's not made for SPL but i was somewhat impressed with what it did.
