SPL & SQ / Fabrication

I have designed a box for a friend of mine. He also has an 86 F150. He heard my system and wants to use my type of subs. The pioneer TS-SW3041D. I have designed a box for him and just wondering if it will be optimum for the speakers. Heres a quick drawing i did in paint: Can someone here that has a proper box building program plug the specs in and tell me if this box would be good to use, or that i should start back over. Any and all help with be greatly appriciated. Thanks in advance, Scott

I know those precision sound ports from parts express are pretty popular so i am thinking someone might have an answer for me when using the psp flared port length calculator (http://www.psp-inc.com/tools.html) is the "flare length port required" from the ends of the flared portion of the port? or is it the straight length portion that the flared ends connect to? thanks in advance

Hello world, after much research and consideration I have finally decided to become an SSA consumer, I plan on buying a DCON series 15in to run with an Alpine MRP-M650. I plan on designing and building a custom ported enclosure for the sub, and this yields the question, what is the recommended volume for said enclosure? I know the SSA Store gives recommended box dimensions, and I have seen them for the DCON 12, but the fields are empty for the 15 D: Any help is appreciated. My guess would be somewhere around 3-4 cubes? But it's my first build so I feel like I need some reassurance. Thanks

I have 4 15's I need to fit in my Altima! Kinda a wierd lineup but I got screamin deals so oh well! I need some advice on how to run everything! I have 2 Phoenix Golds XS2500's and a PPI PC2150. Heres my subs 2 15 inch JL Audio W-6's and 1 15-inchPBX PowerBass XSDv.2 and 1 Power Acoustik 15-inch FUBAR 15W(1000w RMS ones) This is how I was gonna set it up but need help! I was gonna run an XS2500 bridged to 2Ohm to the PBX and FUBAR!(1 to each bridged) than run the PPI to the 2 JL's.... What do you think? I have a cap too a phoenix Gold XSC1o at 1.0 farad but I know I'll have to either get another alternator put in or a Optima Battery! Which should I do? I havent hooked it …

I'm thinking about getting a professional shop to design and install a setup of 2 10" Icon's for me. Reason being is that it's going into a trunk (not a show car) and I want it to be practical (able to put THINGS in the trunk again) rather than having a simple carpeted box ... I want it to look good! I'm thinking about firing in (seats can fold down), sealed off, all carpet ... They talked about covering the amplifiers ... covering my battery in the trunk ... But if I'm paying a shop, what are some options that I should inquire about? Removable plates ... Plexiglass ... Company Logos on the inside deck lid ... stealth on both sides of the trunk ... lighting ... I don't w…

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!

I will be building 2 of these boxes sometime in the next week. There are matched to fit my tiny trunk (00 Mustang Vert)Each is 0.86896 cubic feet, tuned to 32 or 33hz. Each will house a CompVR 10 inch sub, Seeing around 400rms each. The boxes are from a friend so they will be free. There replacing prefab sealed boxes about .8 cubes I would like to know if theres anything wrong with my design. The port is 12.5 inches wide, by half an inch tall. It extends all the way until it is half an inch from the back wall.

I'm going to build a box just want to know were to buy mdf

Here is a link from CDT that has basic knowedge on staging, also includes many install guides and specs for their products. http://www.cdtaudio.com/downloads.htm

well guys i am confused here and i can't figure it out does five 3 inch ports equal to one 15 inch as far as port area????? i know it is simple but i need to make sure for my design.....or also does two 6 inch ports equal one 12 inch port?????? well guy some feedback would help me out a lot.

Height = 13Inches Width = 48 Inches split in half for two seperate compartments one for each sub. Depth1 = 6.5 Inches top Depth2 = 12 Inches bottem Now I donw know much about porting or tuneing. Im running two CVX's dual 2ohm VC wired @ 2ohm load off a 1500.1 zx This long skinny box fits behind my two seats in my pickup truck with one sub behind each seat. When my cousin made the box for me he put a board in the center to seperate the two subs so they both have different compartments. I wanted to maybe port the box to get a deeper boom. But i have no clue how big to cut a port hole... VentedCompact (MinimumEnclosureVolume from the manual CVX12 1.7…

2 BTL 12's. The outside dims of the box are 17" tall x 24.75" deep x 33.5 wide. I am going to use a 8"pvc pipe and make my own flares but need help on length for 33htz tuning. Also with it being an 8 inch pipe do I have to have 8 inches from the back of the box to the end of the pipe? Also how long should the pipe be to be 33htz? Please help me with this.

I have always been a sealed box guy,so I have NO idea how to tune a box. That being said,how much port do I need in a 1.25ft box with DCON 10????? Will be for daily use playing mostly rock/metal. I was thinking 40-45hz maybe? Please correct me if I'm thinking wrong.

I have a Hummer H3 with dual Sundown sa-12D4's running off a Hifonics BRZ1700.1 with 145 amp alt, big 3, 0 gauge, 8 gauge power wire for the speaker wire. I have them in a box with dimensions 38x21.25x14; .75 mdf. The port is 12.5x4.5x31.5 long. I have made the port longer and shorter and can't seem to get it to peak around 34hz. It sounds like it is peaking around 38 or so to me. I have built many single sub boxes, and all of them end up being just about perfect, but I can't seem to get this dual box to sound correctly. I have made 3 different boxes trying to get my box hitting the lows well, but can't seem to do it. Could somebody please help me to get the right …

Does anyone have pics of there enclosure design/system used for new USACI Trunk Class? Or possibly a trunk system that does really well on the term lab?? Here's a link for the rules in USACI.. http://www.soundoff.org/rules.htm

So I'm taking my setup to a 1x event in timmonsville sc. I'll finally be getting metered on a t/l, but I'm wondering what I should bring with me, and if anyone has any tips. There are 2 classes they said I could compete in, truck/suv or something else like extreme personal or something like that. I don't know what would be better, or if it makes much of a difference because like I said, it's my first competition. I've already been told not to do anything to drain the batteries before getting metered, don't know how sound that is or not... Just wondering if there's anything I should know before driving 70+ miles away tomarrow moring. ;D Thanks.

SO I am finally looking to replace my factory starting battery and I am looking at a couple different options. THe Powermaster 2400 or 2700 Kinetik HC2000 Tsunami/Yellowtop (not really looking at this option just put it here) NSB 90 Stinger 1000 (their newer line) Just looking for suggestions. My budget for battery would like to be less than 200 if used or 250 or less new.

I need some advice on whether to go with 2 btl 15s or 2 btl 18s. I have about 16 cubic ft of space to put a box in my car. I will post pics of the car asap. I am just looking a system that hits hard hopefully around 148 to 150 dbs.

So I just got my SAZ-1200D and Diamond Audio TDX 10D4s wired up. The box I built is 2.5 ft^3 (after displacement), tuned to 33hz. Now the question is: If I build a larger box but keep the tuning freq the same, would the subs sound the same? Hit lower? This setup bangs for 2 10's in the 30-40 range, but doesn't quite hit the super lows that great.

Shizzzon as always if anyone would llike to chime in feel free. Shizzzon has been such a big help to me I wanted to ask him in particular about something I know I have faith in him for. My Port Love everyones ideas though so again chime away! 4 Shizzzzle I've been trying to send you a message w/ my phone #s and invite to for you and whomever to stay at mine and Kelly's home. For some reason I'm not able to send. In the attempted PM i got carried away w/ the following so I'm just making it a topic so I don't lose it. (computer has been acting up maybe on last leg) This would be the help I need from you for my "big boy" system! My previous favorite enclosure was…

okay new here and was told that you guys could definitely put me in at least a general direction. here goes I have a customer who had three 12" L7's powered by 3 hifonics bx11200's in the trunk of his 96 J30. the box it self was a sealed, non-separated, box that was just big enough to wrap around the woofers and fire at the rear with the box jutted up against the gas tank that resides there. he is asking if there is any way to build a box that would be noticeably louder yet still retain the punch of such a constrained box. he doesn't mind the loss of his trunk so but the real challenge is figuring out how to get the sound to penetrate through the obstacles within the trun…

If I were using the RE enclosure calculator, do I need to take into account the speakers displacement for the tuning? Should I tune about 1-2 hz below my desired tune hz? Any input would be greatly appreciated. Also does anyone know what a Kicker L7 would like the box tuned to? Thanks!

I cannot decide on what to do. 4 SA-15"s in a standard ported wall, or 4 SA-15"s in a 4th order bandpass. What are the positives and negatives of both? I've helped build a 4 15"s wall in the 60's and an 8 12"s 4th in 60's. I like them both, both sound good, both played well. I just cannot decide on what type of enclosure to build.

I'd appreciate any help you guys can give me on this.... I have a 12'' Nightshade on the way and need some help with the enclosure. I currently have a 10'' Fi BL in 1.6 cubes tuned to 35 hz in my reg cab Ranger. I know it isn't the prettiest thing in the world, but it's the optimum size for the 12'' Nightshade and I'd like to re-use it. My first problem is the mounting depth.....I'm going to have to add some spacer rings to allow the Nightshade to fit depth wise and obviously I'm going to have to increase the cutout to allow a 12'' 12 spoke basket to fit. I wanted to ask you guys what would be the best way to go about this? Should I make a few circular spacers around the…

I was wondering if i could run two rl-p 18's in only 7.6 cubes sealed after the sub displacement. Sounsplinter suggests 4 cubes for each 18, so would running them in a smaller box not be a good idea?
