SPL & SQ / Fabrication

I need some of you guys to make sure my calculations are good and that this box will work out. This is the first box I have designed to be as critical as needed. I am wanting to try a subs back and port into the cabin approach. This should work out to 6.75 Cu Ft after port displacement and after the 15 " BL's it should have 6.39 Cu Ft at about 32 hz. I am wanting to try to make it bigger and get maybe close to 4 cubes per sub. I have about 7 or 8 more inches to work with to make it a little bigger. But I figured I would make sure I am doing this correct before I go and design another one.

hey im thinkin about puttin mirror inside my pox what would be the best way to get it attatched to the mdf with out it fallin off ? any suggestions

i want to make the box fit in my 2000 honda accord and made the measurements on the bigest box i could make 34 inches long 21 inches deep and 16.5 inches high (might be able to go higher) will this be big enough? and how big should the port be to tune it to 32 hertz?

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 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.

i need a box built for a 06 supercrew f-150 any help with be greatly appreciated

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.

Dose any body have contact info for Fi audio I can not find a phone # for them to save my life and my e mails have gone unanswered

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?

I have 2 ReAudio SE 12's. I need a box design ASAP. It's going to sit in the back seats of my 2005 Chevy 4 door 2500HD. So the box can just be square, port center or one side. I want it to hit low ( listen to rap and rock ) but at the same time be ok in comps if I want to go ( for fun but still like to do good. ). The reason I just want it a simple design is so I can remove the box when needed not much room behind the seats so that was not an option. I plan to make this out of 3/4 MDF as well so may need to brace it. I will need a design with all measurements of course. I am just going to have lowes cut the peaces for me. A 3D design would be great so I can see how it all…

Vehicle: 93 Passat Subwoofers: 4 12" DD1500 Series Amplifiers: Unknown, 2000 watts max clamped class Now my initial thought form what ive seeen is a 10 cube box tuned to around 34 for daily and w/e the vehical likes for spl subs clustered up by passenger head rest, port drivers side. other than that im not sure what else to ry when building a wall... So if you have a wall or know of some good pointers please let me know! NOw for a few quesitons: 45° corner pieces or reverse rounds? 2x4"s around the box for supports or just double layer everything? does the location of the baffle matter that much? as in how far away it is from the b-pillar? and how would you find the best…

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 …

Alright, I know how all you guys are happy to help people with set-ups and stuff. So I got one for ya. MY brother was paralyzed sometime around birth. So he is confined to a wheel-chair. He rides around in a big-honkin van. He loves car audio and has always been interested in what other people have. Anyway his birthday is coming up soon and I was wondering if you guys could just put your heads together and help me figure out how and where to put a system in his van. I will have pictures soon. Later Today. It's a '91 Chevy Van with the back seat cut out so he can drive his wheel-chair into it. Anyway I have to go put a water pump in. Thanks in advance for all your help and…

To figure how much air a specific subwoofer should need using the information like, (VCdia: 1-1/4" *Impedance: 4 ohms *Re: 3.6 ohms *Frequency range: 45-1,500 Hz *Fs: 45 Hz *SPL: 82 dB 2.83V/1m *Vas: .24 cu.ft. *Qms: 2.68 *Qes: .61 *Qts: .49 *Xmax 9.25mm) and does any one know a good thing or two about designing t lines.

I checked their forum and it seems to have died off.

I decided to do my blazer in the dark knight them the sub box is going to be the batman symbol the amp racks are going to be the joker playing cards. I need some help in deciding what to do the door panels and battery and distribution like to go with the theme using to svr batteries and and 2 sets of kenwood excelon 6.5 componets in each door.

Hey everyone, been a member here ever since I bought my saz1500D last summer, and I Love it! been running it at 2 ohms to a pair of the older type r 12's in a sealed box since then. Around the time I bought the amp I got 2 of the new R 12's and now its come time to try and build a box for them, this is the first box I'll ever attempt so I dont really know how to get proper dimensions, ive tried the re calculator, but im still unsure if im right....so I figured I'd ask. but anyway vehicle is 98 gmc jimmy so space isnt a huge factor if need be, i can take some measurments of max size subs Type R 12 dual 4's x2 amp sundown saz1500D@ 1 ohm I'd like to have subs firing up slot…

its actally about 5.7 after bracing and displacement, is it too big?

If I can get enough interest I will be doing an IASCA judge training April 11th and 12th in Santa Rosa. I need to get judges up there before I can have a good amount of shows. If any of you are interested in attending a judge training in Santa Rosa please email me at [email protected]. The training is $100 for both days. It includes a full year of membership in IASCA (which is normally $60). Even if you just want to compete the judge training is a great way to get a full understanding of the IASCA rules. When you consider that you get the membership it boils down to $40 for 2 days of SQ instruction. Schedule is: April 11th 9am-5pm -IASCA philosophy -IASCA classes and …
