SPL & SQ / Fabrication

I have 2 Sundown SA-15s and i plan on building a new box to make them perform better. The usable space i have is: Height: 21" Depth: 28" Width: 36.5". How big would you guys make it, what port area, and tuning. It's a daily driver no spl but i would prefer it LOUD

Hey guys. Its time to try something new. Not sure what will happen to the sound if i tune my box higher or make it larger. I'm 1.5^3 tuned to 28hz now. love the flat response curve and helps the sub sound really low. What would happen to sq if I make the enclosure larger like 2.0^3 and/or tune higher? TIA

i just went to my first sq event this weekend and the advice i was given by the judge is to try and widen the soundstage a bit along with getting the image a little higher. i sorta noticed this before but not really so brushed it off but after listening again post judging i could definitely see where he's coming from. he said its slightly above the a pillars and slightly wider then the car but needs just a little more. I listened to hotel cali again along with some michael jackson on the way home and noticed this 100%. any advice on how i would do that? Pointing my drivers side tweeter up helped a lil bit on some songs but I'm pretty sure I'm lacking some midrange up high…

i just got a lightning audio storm x2.h15. v4 and ive been looking for a new recone does anyone know where i might find a new recone?

What I planned on doing is glueing a layer of plexiglass over the top of painted mdf. I want it to dry clear so there will be no glue marks. Is there anything out there that can do this? I have looked and all I could find was plexi to plexi glue. Any finds would be greatly appreciated.

I came across a thread on here where a guy cut slices into one side of a sheet of MDF and then he bent it into a tube! I can no longer find it and i wanted to get a better look at it because i was thinking of using this technique! Does anyone remember where this is? or does anyone remember seeing this? Please post a link to this thread! It would be greatly appreciated!!!!!!!!!! <<<<HAHAHA

Alright so i posted this on an other forum but no one really had any good insignt into what they think caused the tunning of my box become so high from what I tunned it to. Alright here where Im at this is what the box looks like inside its ruffly a little over 7sq ft each side , port is 17.5 inches tall and 6" wide lenght wise its 19" then it L's with the smaller side 8.5" for a total lenght of about 28". So i was thinking i was going to be tuned to about 34hz well after I got metered turns out im at 57hz any idea where I fucked up?

Hello guys, I used to get designs from Ram, but he's no longer in business. Who can help me ? I need a design for a new box. The sub is an Orion HCCA (latest one, 2500 w rms). Tha car is a 206 Peugeot, it's small hatchback car. Ampifier : Crescendo BC 2000 Max dimensions : 35 x 40 x 90 cm 13.78" x 15.74" x 35.43" or 13" 3/4 x 15" 3/4 x 35" 2/5 I want a L port, with a 34 Hz tuning. Goal is loud, musical, not only focus on the lows. It's not a burp setup at all. Sub up, port up. Please. I'm in a hurry !

Every one says that the re-calculator is off so can someone here help me design a box for a 12 BTL Here are my max demensions 15h x 28w x 18d......I would like the box as close to 2.5 after all displacements as I can tuned to 32hz (sub disp is .18) Thanks to anyone who can help.

this is ALTONS post "FYI the box is EXACTLY in the middle of the specs Fi gives for the 12" Q's. Fi recommends 1.8 to 2.4cuft as optimal for a 12" Q, 3.6 to 4.8 for two obviously. If you notice the notes I specifically mention 4.2cuft NET which means before displacements, there's nothing wrong with the space I've given for the Q's." and i STEALTH said "actually net means after displacements. gross is before. lol" ALTON said "taken directly from the dictionary buddy: gross    /groʊs/ Show Spelled [grohs] Show IPA adjective,-er, -est, noun,pluralgross for 11, gross·es for 12, 13; verb –adjective1.without deductions; total, as the amount of sales, salary, profit, etc., be…

I recently brought a pair of LvL 4 with LvL 5 coils to go with my single Autotek MM4000.1D amp. I want to put these subs in an 07 Chevy Suburban LT.The idea is to keep my third row seats. That was the main reason why I brought a suburban instead of a tahoe. So far this is what I've came up with. *Note all measurements are external* Height: 23 3/8 inches or 28 1/2 inches if I go up to top of headrest Width: 49 inches Depth: 28 3/4 inches I went to 12volt.com to use their volume calculator and it came out to roughly 15 cft of internal volume space. I want to go ported with the 18's and I want to go both subs and ports facing up as apposed to subs up and ports to the rear. …

Hi It just got to my head that I should probably get rid of the box I have and make one myself. The one I have was bought from a shop and I dont even know what it is tuned to or the cubic foot. From the outter measurements, Im calculating 1.75-1.80 cubic foot. Here are the measurements of the current box I have my Pioneer TS-W3002D4 Well, basically I want my own box so that I know the exact tuning and size. First, I would like to know if its good to have a 12" tunned to 32Hz since thats what I want to have my box tuned at. 32Hz with ~1.80cubic foot AFTER subwoofer displacement. I would prefer to have subwoofer AND port facing the same way and box measurements ~15-16inche…

Hi.. this is my first build so i have little experience right now. Im getting 1 ICON 12 with either an AQ1200 or an AP1500 amp. I drive a 2000 jetta, the trunk is about 40 inches wide. I am not really sure what type of enclosure i need, the specifications for it, or where to get one so any help would be nice.

I am currently trying to make my doors more rigid. I was going to use 1/8" thick aluminum bars but I do not want to weld them to my door skin as I will have to repaint my car. I was told I could use pl premium but I have no way of clamping them down for 24 hours. Here is my solution I was going to just coat the inner skin of the doors with multiple layers of fiberglass. To get this to stick to the skin I am kind of clueless. Would sanding the door with a heavy grit prior to fiberglassing be enough?

I am planning on designing a box for my rli-8s I am getting and I am trying to figure out a way to latch down the box in 2 places. I want the box to sit in the well for daily driving and I want it to sit up top when I take the t-tops off. I want to design something like the back seats on the nissan quests. There is a compartment where it hinges down into to stow the seats. I am thinking about going to the junkyard and looking around for some hinges and latches that I could use. Does anyone have any ideas? I can draw it up in paint if yall want. Thanks guys
