SPL & SQ / Fabrication

Ok so i have been doing a lot of research for the past 3 months on my plans for a setup. i decided that i am going to go with 4 18"Fi SSD in a blowthrough enclosure designed by peter kulicki (still designing) with a Sundown 3000D (still saving up for it). but my dad told me my subs are going to kill my highs. currently have 4 kicker 6x9s doing the work but i am looking for some suggestions on an extreme setup for some highs in my single cab. by extreme i mean i want way more than a set of comps and tweeters. any help will be appreciated if you wanna check out some pics of my truck you can check it out here!! http://www.cardomain.com/ride/797852

hey guys, im having a hard time deciding on which box to build for my 18" nightshade. i will be using a hifonics brutus bxi1610d amplifier. i have a fairly small trunk but the sub will fit with a correctly sized box. i used the re calculator to come up with 2 different designs. i need your help to choose which would be best. here is the first one http://i903.photobucket.com/albums/ac235/thebiggmann12/2.png and the second one is here http://i903.photobucket.com/albums/ac235/thebiggmann12/Untitled.png the one with the port along the bottom would be port back sup up and the other one would be port up sub up. it will be going in a hatchback focus. if u need any more informati…

i currently built my first box ever...and it came out pretty good...there are some minor gaps...which i believe are due to warped boards because all cuts were made by me on a table saw...but back to the point...i siliconed the crap out of the inside and silicone into the port (around the port pieces and one of the other corners) will that change anything such as tuning? or increase the liklihood of port noise etc?

just wondering how to find out what frequency to tune a box to? do you base it off fs?

Just bought 2 of the old version BTL 12s loaded with the 3rd mag and everything. But Im trying to save space for more room for my batteries and amps. My amps are going to consist of a T40001BD and a T5002. Im going to do a semi blowthrough in the trunk of my Thunderbird in which the back seats do not fold down but Im going to cut out the rear armrest and use it to help let bass escape into the cabin. I wanted my enclosure to be subs and ports forward sealed off from the trunk. I'll have about 8" between the back of the seat and the front of the enclosure. My deminsions will be (double baffled) 15"H x 38.25"W x 23"D. After sub displacement,bracing, and 45 degree corners (r…

Hi I recently had a box built by someone and I want to make sure the tuning is right The ports should be tuned to 33hz The box is for (2) digital designs 2500 12" It is a dual 12 box, sub + port firing foward 34W X 14H X 24D outer dimensions 2 ports come together in the middle and are fully seperated til an inch from the front the 2 chambers are completely seperated down the middle an outer dimension: the port walls on both sides are 18 inches long into the box inner dimensions the port height 12.5 port width: 1.75-2inches (starts at 1.75 at top, slanted to 2inches by the bottom) I hope this isnt too confusing I can try 2 take pics if needed but id have 2 fi…

After i told him my system he txted me two days later telling me he got a new system he said he got four dual 2 ohm 12s running off a 1400 watt rms amp and he says the box he has is 1.4 cubic feet per sub sealed but he said its tuned to 40 hertz. You cant tune a sealed box cam you? and anothr reason i dont believe him is he drives a pt cruiser and when i asked he said he still has his back seat in. Could u even fit an almost 6 cube box in that timy a** storage compartment? Thanks for all replies

Here is the quick rundown: 4 Soundqubed HDS300 FS 33.65 hz QMS 6.912 QES .769 QTS .692 VAS .782 Ft3 Outside dimmensions of box: 16.3"x41"x27" = 10.44 all setup in a common chamber Port size: 8"x40"x65.88" @ 30 hz I believe this is all correct but what a double check before I build this box. Thanks

I know you have to put slits in the wood, but how do you know how deep and so on, is there some type of formula? I know i read it on here some where, but i just cant find it.... Thanks,

Wassup y'all, I'm about to start a box for a 21 in death penalty. I'm going for 9 cubes at 30hz with 3 8in aero ports which equals 150in of port area. Is that too much? I've heard the sub will not handle much power? Someone help me out haha

Im going to be building a sealed trunk enclosure. I have a Zv4 15 that will be firing forwards. The amp will be a BE.2500. I need some advice on how big the box should be. My max dimensions are 15.5 tall 42 wide and 36 deep. I would like to use an aero port instead of a slot port. How wide and long should the aero port be if i wanted the tuning frequency to be at 30 hz? Also, if im going with an aero port, does that mean the box size doesnt have to be as big to accommodate the slot port? To get the 68 in^2 port area would i need to have two aero's or could i get away with just one? Any help is appreciated.

I've decided to build a box for my 15" SSD that will fit in my trunk. I was wondering if these numbers sound right or what it really should be. Lol Box will be 28" wide, 17" tall, and 22" deep. Port is 3.5" wide and 21 inches long. Looking to be around 4cuft tuned around 31- 33hz Does this sound right?? If not help is very appreciated!

Is there anything I should look at when deciding where to put the port? Middle port, top port, driver side port or whatever. . . It is a b-pillar flat wall with 2 zcon 18s on 5k plus at first

in a hatchback, anybody personally experienced a setup where the subs were within 3.5" from the glass producing over 2,000w of power? Is there any danger or am i worrying too much?

well i competed today w/ my new amps. 2 rockford bd 1500's on my 2 kicker L7's in a new CRX and just thrown, finished at 3:30am we did a 147.7 on the new termlab. good thing is we didnt blow an amp so now we can progress instead of blowing an amp everyshow. now to play and get loud :boink:

i have been killin myself trying to figure out a box design for my ranger and have gotten nowhere with it. i got a couple reply's on other forums but nothing set in stone. the sub is a 15"btl and my dem are 50" wide x 16 tall x 16 deep, 5.9cf before sub displacement and port displacement. i need it to have ports on both sides of the sub cause i want the sub in the center of the box (its that way to even out the weight in the truck). i would like it tuned to around 33-34hz.. any help on figuring my port length would be great. please put in laymans terms cause i am not very bright when it comes to this kinda stuff. any help would be greatly appreciated, thanks btw the sub…

I decided on a vehicle, and am just waiting for my check; In the mean time, I have some money set aside to start on the system in the new truck. So far i've decided on the equipment for the front stage (Zed and Crescendo speakers) just not how many lol. I think $1250-1500 is fair for a setup; and that's what i'll put towards the subs. (tax money will pay for the front stage ) My goal is as loud as possible below 40hz. I sold my BTL this morning, bittersweet, I only got to enjoy it for a few days before losing my truck But the new plan is a bunch of obsidians on a hifonics BRX 2400. I'm thinking four 18's, 24cubes @ 30hz. That is about half the budget there, plus…

1 18" DC Level 5. Still waiting for some other bits to come in (amp/battery). But in the mean time, we want to go ahead and start on the box. We were thinking of these two options. 1) Sub up/ports up. Have sub in middle, with a port on each side of sub instead of a single port. Does anyone see any negatives to this besides using up more wood/cost more? etc... Basically would like to do it this way because OCD side is taking over, and we would like to keep it symmetrical. 2) Sub up/port back. This would just be sub up, with a single port along the bottom of the back of the enclosure. Pretty straight forward. Basically, just looking for yall's opinions. Which do you t…

Yup I finally made a decision and the sub is in the mail!! My sx12 will be arriving soon and I need to build a box. I want to give it about 2.5 cubes after port displacement tuned to 34-35 hz. Building the box is not a problem, I got that part down. I just need help figuring port area/length. So any way you guys could help out would be awesome!! Thanks Tom

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…

Hey guys, got a huge favor to ask, i'm doing my first build for a customer, for a neighbor, for an Icon 15d2 in about 4cubes @ 28hz forward firing in a 01 deville What should I shoot for for port area, and have any of you done forward firing setups in a deville before? I'm tryna make a good impression lol. We're going to carpet it to match the trunk for a stealthy look, well, as stealthy as a ported fifteen can be lol. It'll fire through the ski pass. I guess I'm super anxious about it since building for yourself you never have to worry about an upset customer, you just rebuild. Thanks in advance. Edit: It's for a blend of all types of music, and the mids and highs are t…
