SPL & SQ / Fabrication

Final thoughts before I start building this for my sealed trunk wall? I am going to be putting in a Zv4 15" running on a BE.2500. Will it be alright for the total port area to be 12 in^2 more than the recommended? Thank you.

well i am starting the build for 1 zcon 15 tomorrow and i have a few final questions id like to get out the way to make sure this is done right the first time..... 1: should i put 45degree angles in all the corners for better airflow??? here is the link to all the dimensions and everything im doing (thanks Alton!!) Post #11 this is my daily set-up so im not going all out for spl.... i had another question but i cant think of it at the moment... haha im sure ill think of it here shortly so ill post as soon as i do haha thanks guys!!

I have a sundown sae 1200d, which can handle 1500 at 1ohm..... I also have a 12 inch fi bl fully loaded. Would i have to get an extra battery or do the big 3. Will i be fine if i just do the big 3 upgrade? I have a zero gauge amp kit.

Im about to do a build for someone and wanting help with the enclosure design. They are wanting a c pillar wall with port across the top. Its for one 21" warden on a sundown 4500. High output alt. I think 4 100 ah batts. Big 3 . Needing help with how much cubic feet and port area Ill start a build log once the enclosure starts Vehicle : 2000 Tahoe Location in the vehicle: c pillar wall Space available (Length x Width x Height): 24 deep 32 wide 36 high . . Going to at least double layer 3/4 in. wood all around Subwoofer make and model: ia warden Subwoofer Size: Number of Subwoofers: 1 21" Type of Port (Kerfed, Slot, Aero, etc.): slot along top of wall.

I want to built a box for four 10" Dcons max demissions are 37"W x 15"H x 22"D but can stretch the depth a little. . Im using a rockford T1000 at 1ohm. What is suggestions out there thanks in advance

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.…

Just made a new box for my 21" dp (the amp I will be running is a sundown 3500, I have (2) 1750 strapped right now about 3000 watts) in a 2000 Ford Taurus. (8.3 cu ft/32hertz) The sub is facing up, with a top on it to direct wave more in the car and stop trunk rattle. The port is firing in the car. (I guess its sort of a 4th order/ported box combo) During the build I wanted to make sure since the port would be firing in the car and the sub facing up with a top on it, to completely seal the front wave from the rear trunk. After the installation, it was loud but noticeably louder with the trunk open. Ok I must have missed sealing something..... I noticed I missed a few spot…

ok, i did a 143.9 w/ my 2 15's. and i'm wanting to redo the box to try for louder. i'm putting about 750-800 to them a piece. do you think i could get 1 15 w/ 1600w louder than the 2? or would i be better off sticking w/ the 2?

I have an audiopulse axis 15 and a saz3000. I finally got my non-blown sub in the box and in the car. I was tunin it all and saw my hair movin it the window, so i got my gf to come over for a try at a hair trick. enjoy

How much port area you think would be best for 2 18" zcons. . Will be in around 16 cubes in a b pillar flat wall on about 5-6k rms

Just to start off, I'm building this for the heck of it and recently picked up an inexpensive Memphis audio 15-ms84 to build a box around. This box might be placed in a car just to see what it will do but will stay mostly in the office. The pictures should give you an idea what I'm trying to do, and should show most of the specs of the box. Basically using an 8.25" x 1" slot port that is 23" in length with a tuning around 38 hz. The box volume is .59 f^3. The response curve seemed to have an nice flat-ish shape that hopefully will make it sound 'full' to the Fs. If I'm doing something completely wrong, please let me know - Gently please. Thanks John

Please contact Josh at http://www.facebook.com/#!/josh.w.hart or http://www.facebook.com/#!/groups/449888281732464/ and PLEASE tell him I sent you! He is truely a great guy to deal with. I was sent to him from Duran. He responds very fast, and is easy to deal with. He has just finished up my design for my 18" SSA Evil and really went above and beyond my expectiations. This is not just any ordinary designer who build an enclosure around your limited space. He actually aims for your goals and utilizes your intended goals into every aspect of the enclosure. When you message him, I would suggest to include any additional information that you may think that could help the desi…

Hey guys I made this box for 2 audioque 12 hdc3 subs and i want to know if this is an optimal design and if you guys have better ideas give me dimensions i want 36-37 hz thanks guys heres my design the slot port is going to be the bottom so the height is actually the width

I came up with this design for my subs, but I am having trouble figuring out what size the enclosure will be since it's an odd shape. Just wondering how much space each sub will have with these dimensions.

I have four massive p3000 amp. ( rated. 2660 @ 4ohms) I what to istall 4 btl 18s. Need the opt. Enclosue size.(ported ) sq is important. Spl would be nice. I would like to use 5 cube. Per,but have 10 cubes per.

I am thinking about picking up a new ride to play with and probably compete in. i know CRXs are concidered "loud" but what about a camaro. Similar shape. much bigger ballz! anyway i was wondering if anyone has seen any loud camaros at the shows.

Hi all. Just wanna show you vids of my new daily system. As shown in title we have 12" Fi BTL N3 and MB Quart Discus 2000.1. Sub connected 0,7 ohm. Box about 2.2 cuft tuned 36-39 Hz. Battery 65 Ah noname . They do more than i expect . Feel free to comment ! Watch until the end and use HD.

Bass race death match was awesome to, I'll get the video later. Anyway, I built for this thing and I won, it ended up with a 146.1 for a 5min average. It could have been higher but there was no need to turn it up (as you'll see i started at a 148 and backed it down) This was taken this past weekend in Augusta, GA at one of the db drag events. Car off, 5minutes, four loudest street cars at once! I started high, and then turned it down just above the guy next to me. The guy with crx got a late start, so he only did a 138(burps a 151), the guy in the red truck had 2 L510's and a Orion 1200D and held a 138 for the 5min. Not bad! It was a looong five minutes sitting inside …

There used to be a few threads about things people were doing for SQ competition and some of the things each organization makes you have for max points in each category. I have a few questions about some of those things. I will be building based off of Usaci rules mainly because besides SBN (which offers Iasca as well) they have the most SQ comps in logical distances from me. My first question is about Processors, crossovers and EQ's. Do I need any of those three for max points or if I buy a HU that has all of those things built in will that count? If need be I will buy a cheaper HU and add something like the PPI-DCX730 as opposed to something like the Pioneer 880 or the…

Attempting to fit two 18" drivers (fi bl) in 34" width. Each driver would be mounted to an angled piece of double baffle mdf. I made a simple rendering to give a visual: Width is 34", each angled piece would be 20"x20" and angled at 45degree angle. The distance from edge of box to where the angled pieces meet would be approx 10". enclosure will be ported, most likely with aero ports for the sake of being easy. Has anyone had any experience with a enclosure like this? output wise vs conventional ported enclosures? Does the fact of the drivers being angled towards each other cause any problems, cancellation, etc. any other input? thank you

I'm working on a home theater sub. It'll be an aa avalanche 18 in an 21 cu ft llt tuned to 15 hz. I'm trying to figure out how to cut the complicated bracing in this box design. So I was thinking if I got someone to CNC the bracing I can cut the rest of the boards and will have a much easier build. Any suggestions are appreciated. Here is a link. And some pics of the design. I have the google sketchup file, and was wondering if it would be able to make templates of each piece and print them on a plotter. Then I'd cut them to size with a table saw and cut them out with a jig saw. Link to build post

i hope this is the right section butt.... Im still a nexb to box building and I want to make a ported box. It will house two sound splinter Rl-p 12s. I still need to find an amp so i dunno the exact wattage ill be giving them, but i want to give them like 600-800 a piece so thatd be 1200-1600 total. I want kind of an LSQ tuning so would 34hz be alright? (thats what the site suggests) If not then just tell me what you guys would think the best LSQ tuning would be. Then how do I figure out the dims of the slot port once i kno what hz i want??

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.

Subs:2, Sundown Audio E-12 v1, 400rms Amp: Hifonics 1700.1 wired to 1 ohm (so 850rms per sub) Box. Custom mustang vert box, .9 cubes per sub sealed. Right now the E-12s are reversed mounted to get the most usable airspace. Is there a subwoofer that would better handle the power such as the soundqubed HDS 200 or 300. Also, should I stuff the box with polyfill or something? I can't turn my volume up to even half on some songs before the subs start to distort or bottom out. So what can I do to improve my setup?

For those with hatchbacks and/or hatchback experience. Folding rear seats, so large enclosures will work. What enclosure has worked best for you? CRX style? Sub up, back, forward, or angled towards glass? Port up, back, forwatd, or angled towards glass? Daily driver. I'm tempted to try something in the Mazda for the uberwoofer. Can be pretty large, so uncommon enclosures can work as well. It'll boil down to having the sub and port firing forward between the seats or any of the above ways.
