SPL & SQ / Fabrication

im building a box for a Pioneer TS-W1207D4: 1.65 cu ft 3"x5.5'' port displacement: 0.076 the box ive built is about 1.9ft^3 without any displacements. i'm assuming the 3"x5.5" is the port area and i just need to calculate the length? if so, how long do i need the port for ~35-38hz?

Need suggestions on bracing for this box. Would a single 4x4 in the center of this box be enough bracing for top to bottom. I haven't added bracing from side to side or front to back yet. Total top width is just over 52 and bottom is just over 41 wide 38 deep and 18 tall designed for 4 12's

i switched to the Pap Moabs 2-15" and switched to a set of batterys 8v & 6v tied in sieres do a 14.97v and im not sure if it was the batterys or the subs that made the differance so im going to put the 2-15" SoundStream back in the boxx and see if that is the cause of the 2db drop or the batterys ? i need a bigg@ss battery charger...too cook the batterys to 20v and try agine !!! any input is welcome the guy grinning to the left in the background is my friend BEN we put his 2-15" Mtx 9500 subs in my old boxx & he beat be with my own boxx by 1.6db / 150.6db the boxx was built for street beat @ 35Hz his peek was 46Hz

i have a box with 4.4 cubes after sub. it has 2 4"x12" ports can some one tell me what it is tuned to please

I ordered two 12" D1 Icons and want to build a box for them before they get here, but I have only built one box before and have had three pre-fab box's before. In all of my sub setups (total of 4) it seemed that my very first enclosure "folded horn" box which is what the salesman told me it was. . Was it actually a folded horn box, I have no idea, BUT according to everyone else apparently you could hear me about 5 blocks away with two 10" memphis subs 250rms each. That box seemed the cleanest i've ever had and it had the port in the middle of the box with a wall in the middle of the port running parallel with it, so basically each subwoofer had its own chamber. My questi…

Hello all, I have discovered I am going to have to build a new enclosure for my subwoofer to fit in the current vehicle I drive to work. The car is an early 80's sedan with a large but shallow(height) trunk and I do not really care if I have much space left over. I am pretty good at building things and have no problems making a pretty elaborate box, so my question is: In the trunk of a car like this what is the best enclosure to build without walling off the backseat? Any suggestions would be greatly appreciated! Thanks in advance, Mr_Jones

I talked to Nick at Incriminator Audio (Subwoofer Maker) I believe, he said go with 2.5 Cubic Ft per sub and a 70 inchs port in a 6 Cubic ft Box. 2x Incriminator Audio Lethal Injection 12 Inch Subwoofers. I did some further refinements. This is what I came up with Subwoofer Volume - 2.5 Cubic Ft Port Hz - 32 Box Specs: Width - 36" Depth - 26" Height - 14" Net Volume - 6.36 Gross Volume - 5.08 Cubic Ft Volume Per Woofer - 2.54 Cubic Ft Volume Displacement: 0.22 Cubic ft - Woofers .056 Cubic ft - Bracing 4x 45 Degree Corner Braces 1 Cubic ft - Port Volume Port Specs: Port Volume - 1 Cubic ft Port Area - 91.05" Squared Port Diameter - 10.77" Port Width 2" Port Height 12.5" P…

i had an idea similar to these enclosures for my next project and i was wondering is there any downside to having one built like this?

Vehicle : 2014 Toyota Corolla LE eco Location in the vehicle: trunk Space available (Length x Width x Height): 20 x 38 x 16 Subwoofer make and model: American bass xfl 1244 Subwoofer Size: 12 Number of Subwoofers: 2 Type of Port (Kerfed, Slot, Aero, etc.): Slot What type of music do you like?: Rap hip hop deep bass Is your goal SPL or Everyday Music?: Everyday driver Tuning Freq (Hz): not sure Volume : not sure Questions: I'm gonna need a cut list and hopefully it can be a simple design because its my first build attempt

im makeing this post for ppl trying to use fiberglass on there install's. this will help you understand how and what to use to make the job easyer. i will have more later and hopefully have a step by step so you can see it at work.... so here we go... the material's you might see is fiberglass this came's in many form's such as chop mat, cloth, fleece, speaker grill cloth and speaker carpet. next is the resin again came's in many form's, polyester and epoxy. these are the most used in the car audio world. other thing's you'll see is PVA, mold wax, MDF, bondo ect ect.... (and a few time's steel mesh, but i never used it.) ok now im goin to talk about resin. the resin we mo…

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.

If you run the port externally, does it take up space or add to space inside the enclosure. Same idea as inverting your subs, they still take up space inside the enclosure, correct? Thanks

i have a 2005 tahoe with two orion hcca 15.2 and want to build a box like the one steve meade has for is 4 18's here a couple of links...sorry dont know how to put picks up https://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&docid=x6V8eu8o53qyjM&tbnid=EQYYPTVbyxj2eM:&ved=0CAUQjRw&url=http%3A%2F%2Fstevemeadedesigns.com%2Fhome%2Fmemberbuilds_5.php&ei=Js_tUumTLOqe2QXA8oHYDg&bvm=bv.60444564,d.b2I&psig=AFQjCNEvJXWf_OhHZbJlaEYPPEtNZET1bA&ust=1391403157918733 http://cs12828.vk.me/u109393749/video/l_a71dab0b.jpg

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…

Enclosure for 12 FI BL Just wanted to see if anyone has any opinions on this box setup. 2.2 Cubic feet H x D x W 17" 13.092" 30" It would be 33 hz tuning. With port area of 30.8" . I am using 14 square inches per cubic foot Does this sound about right with my calculations or am I way off? I have the cut sheets written down but not sure if its needed in this post.

Okay. So I've got very limited trunk space. And a small-ish. Budget. I'm hoping for someone to help me with some sort of box design for an FI Q 10, in a ported box. Max dimensions being 30" Wide, 14" High, and 17" Deep. Already have an Amp picked out too that i'm gonna buy from a buddy for good.

Ok i'll prolly do this some time this week or next week. But basicly to put that port in the deck like you guys where saying i would just have to find the total Cu. ft of the whole box. And plug my information into this handy dandy online calculator. http://www.carstereo.com/help/Articles.cfm?id=31 and i should be fine right? not tuning this thing is gonna be hard as hell.lol I already know the length is gonna be like 40in long. but i can make it smaller if need be. And i'm gonna guess and say about 17cu ft. only thing is since its a daily driver and i want to use it for comps, how can i tune it? I mean 45 sounds like a good start, but for daily i dont want it that high, …

I am in the process of building my car and I am wanting to do something different. I started out with 3 solox 12's but traded them for 2 solox 18's. I have 4 crunch Gp3000d's to use but I only have 18 cubes total to use. So i thought of using only one solox 18 with 2 GP's in a 4th or 6th order bandpass enclosure. This is for daily and maybe a once in a while bass race/street beat run. Would it be better to run 2 18's ported or one in a bandpass? If a bandpass how big sealed and ported.

Hey guys I have a couple questions. I did a build on 2- SA-12" V.2 Nightshade and I had a custom box built that is 3.0 cf box w/ a port face that is 40x1.2" and is 23" long (specs I got from SA). The subs are firing up and the port is firing back at the bottom of the box. This roughly give me 48 inches of port tuned at 36 hrz, I heard from SA tech that I needed 15 inches of port for each SQ FT. It sounds great, the only problem is it doesn't sound as loud as my ProBox super bass box did. Any suggestions? I talked with SA tech again and they said raise the tuning frequency by cutting off a little off of the port. I checked with ProBox and the Super Bass Boxes are tuned at …

what would you guys prefer to use to smooth out the corners inside a box, putty or bondo, (and which brand) I might grab some resin and hardener for my RL-p box, I want it perfect before the RL-p goes in, I shold probably do some more internal bracing to make it as stiff as possible to preserve as mush SQ as possible

hello hello. ive just built box for (2) Nightshade 15's, its tuned at 33 hz and really gets down.. im trying to brace my box and dont wanna take a chance of screwing up my tuning and overall eclosure. my box measures 49x24x20. with a port opening of 18.5hx8.5t. i guess im seeking advice on placement and what exatly would be the best to use. my face is doubled and my overall box is 1.25 thick.

Hello, I am looking for some help on whether I should do a sealed box, ported or slotted enclosure for my SA-8 V.2 SPL Dual 2OHM. For now, I'm putting a Sony Xplod XM-GTR2022 amp on it. Which runs 500RMS when bridged. I want to build the box slotted preferably, unless you guys give me enough reason to just do a sealed box if its going to be a better setup. If anyone out there already has some plans for a box they have built for their SA-8 V2, shoot them over to me! I'm open to pretty much anything right now. Im putting this sub in a Kia Forte Koup. Working with 19"Hx32"Wx13"D Thanks SSA!

Hi everyone, My name is Paul Mocan, and i am from Cluj-Napoca, Romania. Adrian_D is a good friend of mine, and one day we decided to transform my 20 year old Volvo 340, in a SPL car... here is what happend. We started with adding a second battery behind the passanger seet, and complettly removed the rear seats. We made a box design with 2 ports, one for SPL and one for music. My car was a wreck. I had oil and watter dripping out of it, but it was a crowd gatherer. I'll come back with some pictures...

I have a Fibl 15" firing upwards with a port on the side of my box. I was wondering what would make it louder in the cabin of my car? Port facing me or the rear? Don't know if this will help any but I have a 2010 malibu

07 toyota tacoma doublecab RE SL 10 Pioneer avic f700bt HU JL 6.5 components up fron and JL 6.5 coax in back Preferd matrial is mdf i've got a ton of it. But I am no strager to working with glass and dont mind it if will yield the best results. Im going for SQ im over the bckseat box thing. My goal is a very responsive package that will hit a wide variety of HZ. with ought ruining the sub or the amp. Have not purchased the amp yet but I am looking at Rockford Fosgate Punch P325.1 mono The space we're working with is tight Do I attempt to make an enclosure that will fit the exixting cavity in the starage area or do we pull it out and go for somthing bigger?
