SPL & SQ / Fabrication

Ok, so this weekend I plan on pulling out my box and putting the zcon's in. 2 12" 1 ohm z's goin in. Gettin the diehard platinum marine sat nite and puttin the saz2500 in. Rt now my box is 4.75^3. Its an angled box to fit behind the seats of my 3 door s-10. I have another 4" of room I can go up. That would be about another 1.4 cubic feet or so. Rt now the port is on the side and has about 78 inches of area. 19.5 wide by 4 tall. Is that enough or should I make it bigger while I have it out? Or should I leave it alone? Also what would be a good gauge of wire to run for the subs? I cannot wait to hear these z's rumble!!!!¡¡¡¡¡

Ok whats the difference in one box tuned to 35hz with 2.5cuft and another box tuned to 35hz with 3cuft? also whats the best material to build a box out of?

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…

Time for a new box and im gonna need alittle help. Not really good at box design so thats where yall come in handy. I have two of the new 15" BTLs and i know the box from my x-cons are holding me back at this point. Im figuring i wanna go with 8-9cuft tuned to 34 or 35hz. Port area is whatever it needs to be for a good mix of daily and spl. Im assuming 100-125 for port area will do the trick. Needless to say if you can design me a box and the cut sheets id much appreciate it.

can the single of a L-ported box be divided into two? instead of one port on one side and the sub on the otherside, it will look like ports on both end of the box with the sub in the center? if its possible, is there a calculator online for that? thanks...

I was messin around and just seein where the power wire would go through, and i realized that the firewall already in use for the factory wires was pretty much full, and i don't see how 1/0 is going to squeeze in there. But a couple inches to the right and one or two inches above it, theres what i'm guessing is an unused firewall hole. Its a rubber surround with a rubber filling. I tried to see where it came out on the engine side, and i couldn't find it. Does anyone know if i could (once i find the hole, as it was a little dark when i did this) puncture the rubber filling and take it through there? If not, what should i do?

I plan on going with 3 -10's box will be 3.2cf after sub displacement will be using 2-3 6" external aero ports. Tuned to 32hz and running 2k. Subs in mind are sa's or skar 10's maybe even custom built 10's from splaudio. Box will be subs back port to the front.

Subs: two DC Audio LVL4XL 15's Here is the room I have set aside for the box. I can possibly go bigger. But, if possible, would like to not go bigger. 23 inches high 20 inches deep 38 inches wide I want subs up and the port up. I would like to use a slot port. Tunning could be at whatever would work best with the dimensions given. Anywhere between 30hz to 40hz would be fine with me. I dont know what my cabin peaks at but I have had two setups, one 18 tuned to 32 and two tens, not sure on tunning, Both setups peaked at between 40 to 45 hz. I will be using a US Amps AX3200DE to power them. This will be in a small SUV, 07' Honda CR-V.

About to build a box for 2 15"s FI BTL's that will be going into a 87 Mustang. Each btl needs 3-5 ft^3 and is .21 displacement. This is my first Wall / Semi wall build so i just wanted you guys to look over it and tell me what you think.

ok so i want to make a box with 1 15 in the middle and 2 poorts, 1 on each side, to get it how i wanted it ported, could i just measure out the space i would need for 1 port and just put half of that on each side?

Im looking for a box design for 2 15" Mtx 9500's for my 07 civic si 2dr,(H16xW40xD26 Roughly) Im looking for ported,trying to do subs facing inside the cabin with port the same. Any help will be much appreciated....... Mtx recommends 2.48 net enclosure per sub(from there website)(W 24xD 17xH 16)Port 2"x14.5. Now my trunk dimensions are 40w x 26d x 16h so i think i can make this work in my trunk...Right?just by taking 4" off the width and adding it to the depth and then make a 4" port........Can someone help me out with this....PLEASE??lol I listen to mostly rap and rock(for port tuning) Which of the following is the sub displacement?That would have to be minused off the…

Does anybody know where one us i want to see what i can hit?

Are 45*s needed with in boxes that use PVC tubing as ports? Also I designed my box using Win ISD and was told to make the box roughly 2.0 @36hz and use 10" of 4" pvc. Now does WIN ISD take in to account for the space taken up by the PVC or do I have to make the box larger?

I've spent a couple hours sketching up various designs on re calc and torres box calc. However, all I hear about any of the box design apps out there is that they are total crap. Working as much as I do these days I simply don't have time to become an expert in this area. Also understanding that install is a huge factor, I don't want to screw the design up. I am looking to build something this Saturday and want to get it done right so I don't have to change it again because of an improper design. I know there are a bunch of you out there that can do this stuff in your sleep. I don't mind paying for a solid design with cut sheet, etc. (i have PayPal) I also don't need anyt…

Would it be better to but 45's here or would it be bad? The pics will explain it better. Option A. Option B. There are two, one on each side of the port. The box is 48" wide and the port is at the bottom in the middle, and is 30" wide. There is a 45 on the back opposite of these.

im looking if you have some photos of pvc tube with aeroport im looking forward to prove this on my car thanks i have some photos and i wanna see if you have som more for the experiment thanks something like this but i want to put 3 aeroport per pvc tube some smaller aeroport to check if this is better than sealed pvc ohh its for 15 RE XXX

Is each quantity for a 17" Long tube? What if it needs to be longer? 4" Port Tube

((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

So I've been reading a ton about aeroports and I've heard they reduce port noise and take up less space therefor reducing box size. I want to do two SA10's in 3 cubic feet tuned to 33 hz. I've been trying to use all sorts of different calculators and such trying to figure out port sizes and what not but its not coming together for me. Basically I want to know how you figure out port length and diameter as well as port displacement in the box. Also where is a good place to get these ports from. I'm going for a really nice sounding setup that can get loud if I wanna show off a tad . Any info I didn't include just ask and I'll do my best to fill in the gaps. Thanks BumpinAl…

This is what happens when you get wood cut at home depot. I got all my cuts at home depot and some are 1/16 to short. they wasnt using the regular saw. i was wondering can i use some sealer tape for the cracks?

I am ready to finish my box this weekend for my BTL but have a few questions first. When I attach the baffle with the second piece, will the port tuning be changed at all? The top will not be flush after I add the second piece. Ive been looking in the build logs and wherever I can to see if this is what everybody else does. No luck so far. I know its only one side of the port but I want to get it right and not waste wood. Hopefully you guys understand what I am trying to say. I bought like a 2x2 stick for the bracing as it was cheaper than the closet poles. Can I shave off the corners so there isnt such a big edge or should I just go get closet poles? This wont be my fin…

Alright so iv made my box and everything and I would love to use body filler to smooth t all out and cover allscrew holes. I don't really want to spend any more money for this box... What's the cheapest way to obtain the perfect box?

Hi I am starting my build very shortly and I have a question on making the sub box. I have made L slot port boxes before but for my 2 12" Fi SSDs I want to make the port in the middle. So the question I have is can I make it by just calculating for 1 of the subs and just build it together? Space is not an issue. Thanks ahead for all the input

This setup will be in a 1985 celebrity wagon. I want insane, air moving hard hitting lows. Two different setups.... 1. I was considering a wall running directly behind the front seats with 4 L7 15's and the most port I can run and still have a low tune. I'm guessing about 300 square inches of port. 2.Another idea I was considering was running a huge box with subs up and port up that starts with the box directly behind the front seats and takes up all cargo area, but keep the box just tall enough to have the port firing on the angled back glass. Of course the port will be as big and tuned as low as I can logically make it. On the 2nd idea I was going to run a lot more c…
