SPL & SQ / Fabrication

My db drag partners ride this season 4- AUDIOPULSE 15'S, WALL 8- AMPS STRAPPED, 20,800 WATTS RMS 8- BATTERIES 2- ALTERNATORS= 510 AMPERS AND 300 INCHES OF PORT -Each amp at .5 ohms just like my sundowns (same wiring on the dual amp single woofer strap) -156 legal (156.4 later that night) with three out of 4 of the 15's on -amps have not been matched perfectly yet -woofers have not all broken in -wall still has not been sealed off -no deadening yet -batteries were uncharged

Can anyone make one for me? I'm not very good with sketchup or the cutlist plugin.

Hey guys, I have been into car audio for about 5 years now and I believe I am fully ready to to do what I would consider a high end setup. I currently have a 2002 Hyundai XG350L with my 2 mtx 4500's, alpine amp, and rockford fosgate p1 components and 2 ways in the rear deck, with a P300.2 powering them. I am getting ready to move into my parents new house within the next month and will have a full size garage to work in. This will give me the place to let my mind expand and come up with ideas. I have been looking around at some new subs, I Have a couple of ideas in mind but am open to any suggestions as I havn't heard any system bigger then 2 cvx's on a JL 1000. I a…

due to the complexity of the sides of my box, its going to be kind of hard to build a slot port on the top of the box. i was thinking, instead of a slot port, should i do like 4 6" aero's? (or whatever i need to get the right amount of port area) which leads me to my questions. -if you have 200 (example) sq in of port area, with a slot port, if you switch to aeros, do you still need a ton of aero's to get 200 sq in? or does less aeros equal out to the larger port area of a slot port? -aero ports in a wall. how will this work? i know one con is i dont get the natural bracing a slot port would provide, but ill deal with that, and add some extra bracing. -difference in sound…

Where I work we have this non-flexible polymer composite called synthane and it comes in 4X8X3/4 sheets. Now I was wondering if this woould work for a box? I mean in theory it should, its dense and non flexible. I was just wondering if anyone has ever head of this material. I highly doubt its ever been used as in a box, I would imagine its very expensive.

subs: 3 12" hx2 do i need 4" or 6" ports? tuning suggestions also welcome...i was thinking 6 ft^3 @ 34 hz

Like the topic says. Does anyone know how accurate the numbers are? Port Length Calculator Thanks

I have plenty of room for my overall volume, but fitting 3 10's and a port on the face is my challenge. I am going to have a box of around 3.25-3.75 ft^3 tuned to around 35. I was going for around 60 in^2 port area, my inside dimension is going to be 30.5 so that leaves me with a port that is 2" tall by 30.5" wide. Ive already done the math and have the depth on the box to easily fit the port length, but is there any reasons against a port of this shape? I thought about using about 4-5 4 inch round ports, which is either 48 or 60 in^2, but with either route I need to have ports longer than will fit inside the box, and I will not run an exterior port because this is my dai…

i need help in making a ported box for a re xxx 12" v4 for a vauxhall astra sxi 52 plate could any one please help me

So I'm installing a Xcon 12" and was wondering what would be the best placement of the sub and port? Size of the box and tuning? Or if I should so sealed and ported? If ported what type of port? It is going in a 01 eclipce hatchback!

I need help with designing an aero port enclosure. This is my first attempt. I am looking for 2.5 net and tuning 32hz, With corner bracing. I would appreciate all help I can get! Thanks.

I am working on my plans for my box and would it be acceptable to cut a hole for a round port and have the port extrude from the box some distance? The Box is 3.5 cubes or so tuning to i hope 32 Hz for a 15. Could it be outside to get more airspace?

I just bought a 18" FI BTLN2 and was wondering what is the best way to build my box. It is going in the back of a '97 nissan pathfinder. I know you need 3/4" MDF for the box but can you use 1/2"? thanks

Has anyone done a build in a newer camaro?

I just bought a 15" fi btl dual 2 ohm off of craigslist. The box that came with it is obviously way too small and tuned to high. I was wondering if anyone could help me figure out what size of box and all that stuff I need to get what I want out of it. The current box is 19"x18x17" that's about 3 cubes and inside that enclosure is half port and the speaker. Way too small. It lacks lower end very much. Im running it off of a autotek ss1500 at 1 ohm. I want it to be audibly loud and hit as hard as possible. I have built many boxes but just want to really make sure this one comes out really well. Any suggestions would be appreciated. Thanks.

I will not be competing in SPL contests, i just want LOUD bass (doesnt every basshead). The sub i will be getting is a Fi BTL either a 12 or 15, unknown due to money, I think a ported box would be the best, but my buddy told me that bandpass boxes are better. He said a 6th order box would be good, i have no idea what a bandpass or 6th order box is. Are they louder for the daily user? As stated in title, the car i currnetly have is a 2006 Toyota 4Runner, in it, i have mids and highs by pioneer, and they sound good.

does anyone know the t/s parameters for an oz matrix elite 12.2(dual 2 ohm voice coils) since i can't find the bl or sd measurements anywhere? and from your past experiences what enclosure size,port and tuning is best recommended for maximum street bass?

I have a 4 cubic foot box that i would like to install two 4" pvc ports in... How do i go about figuring it out?

Hi my name is Bosco Ruiz....and i bought 2 TEAM RF 12"...nowadays i dont have a box for those subs.....i need ur help I have a RAV4 2006 and the dimensions inside are. High 38" depth 32" width 34" do u have a picture of box for those subs?? what dimensions would be for my subs??

Alright, so on my quest to get louder out of my trunk, I'm trying to really understand enclosure designs, and how different enclosure sizes effect response, output and other factors. Now I know the general basics, larger enclosures will be more efficient, smaller enclosures less efficient. But I guess I'm looking for some more in-depth information.

I recently bought 2 RE AUDIO SXX 12" woofers and plan to build the enclosure (vented) by myself (first time in my life). Since the manufactorer's web site only provides a box calculator for one woofer, can somebody kindly give me some advice on dual woofer enclosure and port measurement? In order for the box to fit in the trunck, the size constraints are: Length < 35", Height < 16.5". I prefer SQ over SPL and hope the bass hit as hard as they can. Thanks so much! The T/S parameters are listed below and more info. can be found on http://www.reaudio.com/woofers.php#goto_sxx Qes: 0.32 (Electrical Q value) Qms: 4.4 (Mechanical Q value) Qts: 0.30 (Total Speaker Q value)…

I just finished my box for my fi btl and now I'm looking for something to cover it but not sure what yet. I've looked at CF and Carpet together (having the entire box black carpet with the fi bomb sticker as a cutout with CF over top) and thought about bed liner but I've never tired either and I'm not sue what would be the best look and if there are any more ideas out there throw them at me in open to anything.

Okay I am looking for some help in this forum because I am loosing hair over this. I currently have a system in my ride and it is progress though. Eclipse CD 5030 ARC AUDIO KS 300.2 MOREL DOTECH OVATION 6 ARC AUDIO KS 500.1 MINI DIAMOND AUDIO D3 15 Now first things first the KS 300.2 is powering the components at 180 x 2 @ 4 ohms The KS 500.1 Mini [500 x 1 @ 2 ohm] is powering the Diamond Audio D3 15 [1.75 sealed enclosure]. Anyways looking to swap out the Diamond Audio D3 for a Fi Audio sub most likely the SSD 15. I was told to get a single dual 1 ohm sub and wire it in series to make it a 2 ohm sub. Anyways I have a pair of Selenium 6 Midwoofers that are 8 ohm and mo…

first off i am not mister know it all so please bare with i do know a lot but will see . but any ways what is it with resonant tuning frequency? would it be better to tune low as possible for like a t line and get a higher score? unless your talking frequency length. the lower in the octave you got the hard the bass hits right ??? with in reason of course like the sub dropping off and just can't play well at 18 hz were it plays better at 47 Hz etc etc ... because the music energy is reaching the mic at it full potential of 47Hz if you tune to high the spl drops off again so you lose power in the spl right??? so why would you look for a resonant frequency like 18 hert…

I started my base mold about a week ago, and popped it out after the second layer. Right now im on my fourth layer for the base, and it seems to be getting really stiff. Probably going to end up doing 2 more layers. I have a question though, does fiberglassing polyiester rope to the inside of the box help stiffen it up? i thought I read about that on here but im not sure.
