SPL & SQ / Fabrication

Forgot I uploaded these to photobucket Quite the challenge considering it's a crackerbox tracker, that's a manual, and I wear a size 15 shoe. I'll get some more pics when I get back home.

Hey, i'm gonna spill out all kinds of info so make sure you understand it, hehe. I'm currently workin on your design right now, you will be using external dimensions of 42" wide x 17" tall x 22" deep. This IS what i am going with. You will be using a double baffle on this box. Box material will be constructed out of 0.75" material. I need to know what bracing material you will be using, Wooden dowels or 2x4s? Internal dimensions- 40.5" wide x 15.5" tall x 19.75" deep. Your speaker Outer Diameter is 10.91", i went ahead and rounded up to 11" for a hair more headroom for accidental measurement inaccuracy. Your Baffle design- The border around this baffle is showing the th…

I've got quite a lot going on right now if you cant tell, I've got a client's SQ truck and my personal SPL build going at the same time. I've got some great info from you guys on the SQ build so lets try some on my SPL build. Last year we took state records in USACi in Stock 1801-3001, since then we've been addicted to going bigger and louder. We want to be able to still play music so, no pure tones/burp set up. We've got the durango ripped to down to having nothing but a dash, being completely deadened up. The idea sits at building a wall behind the B pillars for 4 18" BTLs. Haven't decided on what to do to power them yet. We have more than enough room to give them all…

This guy is nuts. Many of you have probably already seen this but it was my first time coming across it... Dodge Sprinter

I need a sheet of hard plastic like ABS to use in a bunch of places in my car. Does anybody know where to get anything close to that? I haven't really done any research so if anybody could point me in the right direction I would really appreciate it.

Does anyone know where I can buy a copy of the USACI SQ disc with Hotel California? Or if someone can burn me a copy, I'd be willing to pay...of course.

Id like to get a box done and have a few ideas. Its a silverado crew cab and need a box under the seat. Not sure if I want to go with 2 10s ported or 1 12 ported I wanted to talk to someone who could let me know which would work best. The sub Id like to go with is an RE SEX 10" or a RE SXX 12" or Fi BL 12"

I need a box for two AA Mayhem 12s, and Ive got the external dimensions, trunk dimensions, port lengths and everything. I just need someone to build it because I am in the Army Active duty living in the barracks and I cannot build a box, I need to order one. Please post if you know if a website, or if you know of someone that can build me one. Greatly appreciated guys!

I don't have a disc to install windows on my mac, and I kinda want to use my TermLab. Does anyone know how to do this without using bootcamp or a visualizer?

I want to check some numbers but Im not sure if there are any trustworthy sites.. Got any?

I started a wall and need to know what to tune the box to... Any help would be greatly appreciated.

I would like to know how many or even if anyone uses a 4 inch aeroport for a 12 inch sub without any problems. Reason i ask is because i built a 2 cu. ft. box for my audiopulse axis with a 4 inch aeroport tuned to ~34 hz and it sounds fine, only up to a certain point though. I don't like the noise it makes, i guess that's what chuffing sounds like and i can't stand it so i turn the volume down. I was also only using a saz 1000d on it with absolutely horrible electrical so there's no way i was reaching its limits with it's insane power requirement. Now i know for a fact that that's not enough port area but i would still like to know if anyone uses a 4" and gets away with …

I have a box in my Mustang that's 2.5 ft^3 tuned to 32 Hz that's used fo my 12" Mag D2. If I just swtich out the Mag D2 with a 12" Fi Q, would the tuning still be 32 Hz, or am I missing something?

After watching YouTube and attending a few myself. It appears competitions make the hobby kind of sour. Online were all friends, then comp day rolls around and it's like the wild wild west. I've seen a lot of friends and drama start and end from these "comps" Almost to the point I don't even like attending them. I go to shows to talk interact and enjoy the hobby. I just feel like comps get way too serious. FTLOB!!!!

So my brother keeps telling me that even if i port my box that it will have no effect on how loud it will be, because it is in a trunk and that the only way i will tell teh diffrence is if i have a suv or fold down seats I know this is not true, but to an extent it kinda makes since

Does port/woofer aiming really matter that much in an SUV? I'm looking at placing the box in the passenger rear corner with the woofer firing cross cabin and port forward.

((2 * 250.3125 * 10) - (0.159230769 * 2 * (12^3)) - (30.830229 * 2)) / (12^3) = 2.54299074 cu ft. That’s with port, sub, 45s and skeletal displacement taken into consideration. That makes the box tuned to around 34.02Hz if the math is correct..... let me know guys, what you think it is for 2 dc audio xl 10"s powered by an aq3500d1 in a 1ohm load, think my tunining is to high? still able to hit the lows you think? i wanted to be able to play normal music as well since its my daily driver 1st real build so im just taking everything into condsideration since this box is built already just waitin on my other d3100 to come monday

Alright, so on my quest to get louder out of my trunk, I'm trying to really understand enclosure designs, and how different enclosure sizes effect response, output and other factors. Now I know the general basics, larger enclosures will be more efficient, smaller enclosures less efficient. But I guess I'm looking for some more in-depth information.

I was wondering if the port calculater on the carstereo.com page was worth a poo? I used it to build my explorer (8 kicker comp 12"s and a 2500.1) as that worked out perfect......but i used it to build my 4runner (2 hk802sx amps, and 4 SSD 15''s loaded) and it doesnt impress me at all....so i think i figured out why.....here is the link to the page http://www.carstereo.com/help/Articles.cfm?id=31 But here is my real question...when you are calculating your port.....and you punch in all your factors and the end result tells you how long your port should be.....Does this program already remove the port displacement? Im assuming it does since you have to figure in your tota…

i need to build a box around 2 cubic feet tuned at 33 htz with a maximum height of 17 inches, does this look right? also, sub up/port back or sub/port both back?

Box numbers i got off of the RE Audio box calc. I put in the measurements from my trunk and this is what i got out of it. 2004 mitsubishi lancer ralliart, mtx 1501d, ssa xcon 15. sub facing rear, port facing rear. square vent style port width 28.5 box height 16.5 top 22 bottom 24.5 wood thickness .75 mdf braced and reseined port height 15 port width 4 porth length 1 is 18.5 porth length 2 is 12 total port length 37.25 porth diameter is 8.74 square port area 60 sq port internal volumbe 2235 sq port volume displaced 2257.31 box volume ft3 3.79 box volum in3 6551.43 tuned freq is 31.24 is that to low of a tune for a daily spl setup, something the wifey can listen to when …

ok so i believe my sub box is about 1.08 cuft or very close to that. if i was to add this kit here... http://www.madisound...products_id=711 you think that would fit my application? in order to get 34hz with a single 3" inlet im going to need a "13.06364" long tube. if i got this kit i could cut it to length? what do you think? with a box of that amount of cuft do you guys think i should tune to a different setting aswell? let me know what you think!!

For the past couple of months I have been playing around with imaging. been reading everything I could get my hands on, even picked several brains along the way. I started my project with simple goals in mind. But after listening to others systems, as well as my own. My goals keep getting raised I built the kicks allready. Temporarily using a pair of $1 crunch midbasses ( I love yard sales ) and a pair of large format PE silk domes. Simple inline crossovers. powered by an rf 200a4. To my amazement, and a few others. The sound was rather nice with no processing what so ever. So my goal has now changed once again. I was originally building towards a single seat soundstage…

I currently have Rainbow Cal27 tweeters and Rainbow Profi Kick midbass. I am looking for a midrange to make a "hybrid" 3way frontstage (that words seems rather redundant ) I have a profi crossover and the intent was to place the tweeter and small dome midrange quite close to each other in the kickpanel, while the midbass is in the door. The midbass will be in the door. The specs on the midrange need to be a 2" dome with ~ 1" mounting depth and 4 ohms (because of the crossover, I am unsure how the crossover point will be affected by an 8 ohm midrange. I feel that my 880 should be able to t/a the midrange and tweeter because they are so close together, they will act as on…

Most vehicles are generally louder with a door open, window down vs the vehicle being sealed right? Depending on the db level is there an inverse effect and a sealed vehicle is louder? Or does it just depend on the frequency as an open door would make the cabin part of the enclosure (4th order?) I know there's different sanctions and different rules among classes, so certain cases I'm assuming the vehicle has to be sealed and can't have any windows/door open. So if my first theory is true, then why do people seal every air leak in their vehicle to gain dbs? Wouldn't they want places for the air to escape (like an open door, just not opened quite as much). OR would this^ b…
