SPL & SQ / Fabrication

I am looking for someone in the Portland area to build a box for me. I am very capable but don't have the tools at the moment. I have the design. It a pwk. For 2 12's with a 6" aero. I don't trust the dealers out here, plus they'd want too much $$$.

I am ready to build a sealed box for my single ss rl-p 18, but im not sure which way to face the sub. i have plenty of room on all side. My car is a lincoln towncar if that helps. Also, should i go with the recomended box size of 4 cubes? And one more question, should i only double baffle the front, or should i double baffle everything? Thanks

any inputs and comments for my box design it will be for 2 10" Chaos it is aproximately 3.23cubic feet gross volume, 2.5 net volume will be tuned at aproximately 33hz will be going into a single cab was done on google sketchup the one on the left is with all the pieces seprate, and the right one is the final product thank you

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…

Hey quick question: if im looking for say 33hz from an areo port in a box 3 cubes how do i calculate it if i need two ports? heres the situation, i have box 3 cubes, want to run 4 inch ports. if i make one port its 7.4 inches long but i need more area than that.

I have a buddy that got a got a box from another friend for free and we noticed the port area after the turn at the back of the box isn't as wide as the port at the front. The first length of port is 2.5" wide, and the second length is 2". Will this cause any major difference in sound? I'm guessing it will slightly tune it less at 2" than if it was 2.5" in the 2nd length. Example:

I've looked around for different test tones, i still dont know how to make my own, but i found a site that offers free test tones 10 seconds long. there is a place at the bottom to download a zipped version of all the songs. Stereo, 16 bit, 44,100 KHz 0 db http://www.ronelmm.com/tones/

Hi all Just wondering if someone could help me design a 4th order bandpass box for my AA chaos 12" ive decided i want this for two reasons. 1 i own a sedan with a sealed off boot and this is meant to be one of the best boxes for this application. secondly these subs are meant to be awesome in 4th order. i plan to port the box through the speaker holes in the parcel tray. ohh the car is a toyota jzx100. ohh i also plan to use this as my daily box. thanks heaps.

So, Ive been roaming around this forum to find some ideas on some box ideas for my 2 18" Fi Qs going in a 2000 Chevy Blazer. I listen to mostly rap that go into the low 30hz range and higher so yess this is my daily driver, so Ive designed some boxes of my own to see what you guys think about them. Hereeeee we go... Box Design 1: Separate chambers, 7.25 cu. ft. each after displacements @ 28hz - Subs forward, port forward Box Design 2: Separate chambers, 6.75 cu. ft. each after displacements @ 32hz (I knowww its kinda wicked design but oh well..) - Subs back, port forward Let me know what you guys think!! Thanks for looking :)

I built this for a friend of mine. Its about 2.52 cuft per sub with 40 square inches of port per sub tuned to 36 Hz. The objective was to build a box that filled up the back of his truck. But that was too much air space overall, so we pretty much built a box inside of a box.. The pic of the inside looks pretty sick.

I would like to get a few different tones on a CD or something to play around with, where can I find some? Thanks, Mike B.

Knuconceptz 'Knucar' This guy might have an ssa membership, idk, but has anyone seen this? Everyone says 45 degree angles help airflow, so what would a perfectly round one do? It'd be near impossible to tune if you wanted to port, but if you could, would it actually work? Trust me, i'm not thinking of doing this because i can't make a sphere out of play-dough, just curiousity here.

I need help with a box design for a 15" Mach5Audio MAW sub. The recommended sealed box size for this sub is 62 litres (2.2 cu.ft.) 30hz tuning. I would like an enclosure designed exactly to these specs if possible. Thanks in advance!

I am looking to build another box but want something unique yet efficent. I'll pay for the design. Some specs on the trunk: Cannot be over 14" tall x 20"wide x doesnt matter too much over 40" deep. The box will be for a 12" btl loaded off 2 aq2200s. I would prefer tuning no higher than 32hz. Lets see what someone can do.

Well, I thought this guy was going to help me out with coming up with the specs to build a box, but he barely replies to my emails. So now I am trying to figure out the specs for a box. I would rather build it due to cost, and have looked at the box builders further down on the site, but they are a little expensive. It will be for an 18" Fi btl, as I'm sure many other people have already asked for help on this. I don't have a limitation really for room for the recommended sizes because I have an SUV. Width about 41" from side to side, and I'll have to go measure the height and depth. I listen to rap. I'd rather have it be sub up, port back, but not a side port unless it…

Hey guys I just recently got two SA 8s and I am getting ready for a custom enclosure. I have been thinking about maybe upfiring them into the rear deck of my new Infiniti M35x and cutting holes for the port and woofers. The only issue is that I did this with some Image Dynamic 8s and wasn't thrilled about the how they sounded. Certain people say that give you a cleaner sound any input? I was also thinking about doing something funky like firing port backwards and subs up like you would in an SUV to see if that made a difference in the trunk. Should I just stick with the conventional trunk box? I was also wondering what people were running for box size (i heard .6 per sub …

ive been told that puttin carpet on the inside of a box will make the sub think the box is bigger there for sound better or louder. but i personaly like fiberglassing the inside to gurantee its super sealed and not falling apart ported or selad enclosure which would be the better idea or maybe carpet over fiberglass

3.7 cubes after port displacement with 48 square inches of port vs 3.2 cubes after port displacement with 56 square inches of port. Fi SSD 15" I know it probably wouldn't be a huge difference but which would get louder? In one you sacrifice air space but gain port space and the other you gain air space but sacrifice port space. So what I'm trying to say is which is more important when figuring loudness?

Just starting my build but I need to know about the box. Ive seen sub up port back sub forward port forward, sub up port up. I assume any combo will work but I want to verify. I want to do sub forward port up. IT would be the same as port forward but the port opening would be up instead of forward. So I guess it would sort of be like an L. Thats the best way I can explain. I need the port firing where the rear deck would be and the sub facing forward. The back of the back seat is being removed and replaced with the box. The sub will face forward in the middle, and on both sides the MDF will be foamed and clothed so two (though small) people can fit in the back seat! I don…

I am trying to plan how I am going to build a box to go in the ex cab of my toyota truck. I am putting 2 Fi Q15's in it. The space I have to work with is 53'' wide 17'' depth and 22'' tall. I was told to use 1 layer of 3/4'' MDF then after the box is done add a 2nd layer of 3/4'' MDF to the outside of the box to help reinforce it, is this right? This is the first box I have build so I just wanna make sure I get it right. But this is what I have come up with so far, how does is this right, the subs call for about 4 cub feet each tuned to around 33.

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"

Ok people, I decided that if I can go with around 3.5^ for each enclosure for the HD 15's, then i'm going with that. I know that isn't the optimal size for this sub, but it's just for a daily driver and not doing any competitions; basically trying to bump somebody out on a street situation. If this would be too small for the subs to actually put out at their full potential, then I would have to go with 2 of the HDC312's. I was thinking to take out the rear deck and have the subs/ports firing through there with having the space b/t the box and metal sealed. What's the input on this one?

Hey everyone. I'm starting my first build today and the dimensions of my box are going to be around 34w x 18h x 16deep. I wanted to have subs up and port along the bottom of the box facing the trunk (its a hatchback) and doing that would tune it to high. Am I able to put the port in the middle of the bottom or does the port have to be along the whole edge it is on? If it has to be along the whole edge I will probly put in vertically on the back side on either the left or right edge. Please help, this is urgent. I'm going to be starting it in a couple hours. Thanks, Ted

I saw this done with on RL-p by some one on here. Basically my only motivation to even think of doing this is because I have a Rear Strut-tower Bar that kind of divides the trunk (99 civic cp). So any box I put in is going to either be really small or really convoluted.. and I don't want to do that.. unless I have too. So what are your thoughts? Another idea is to attach it to the seat back and then build a 1.0-1.7cf sealed box around it.

Im BACK! After being gone for a while traveling the world I have come back to my fellow members / friends / people / dudes / dudettes and folks on the good 'ol ssa forums (good job Mark). I am starting a rebuild once again. I literally blew my old box apart so its time to go bigger, badder and more bracing! I noticed a huge improvement from my 3.5cuFt box to my 4.25cuFt box. I hope to do the same when I hit a 4.75 ish box. I am installing into this box a single DC 15" woofer being powered by a 3500D. Here is what my plan is: BOX: Height: 17.5in Width: 38in Depth: 18.5 CuFt: 5.083 Square Port Volume Internal: 1134 Square Port Volume Displacement: 1144.125 Tuning Freque…
