SPL & SQ / Fabrication

Is the opening of a slot port supposed to be on the face of the enclosure, same direction as the sub is facing? All the boxes I have seen have them there...is that the requirement, or, just common way to build it?

so i took my box out of my car to add some fiberglass resin to it, and some supports, but i was wondering what side should a port be on for the best spl. passenger side or drivers side. the sub and port will be facing the trunk. Thanks,

So I don't have a lot of tools and I don't feel like ordering flush mdf rings so is there something else that I can glue to the base of my ring cut out to give it that same look when I fiberglass them...I do not have a router and I'm not going to buy one just to make 4 flush mdf rings...so Im just wondering is there anything esle out there.

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.

Hey fellas. What's going on? Alright, heres the deal. I picked up another CVR, so I am now in the process of deciding what I want to do with the new box for the 2 CVRs. This setup is going to be a pure daily driver, no competing or anything. I listen to all rap or hip-hop. Now, I emailed Kicker and asked what they thought the best daily driver box would be and they sent me some specs that ended up being tuned to around 40 hz. I thought 40 hz is pretty high for daily driver tuning. I PM'd Polecat and he said that 40 hz would be good and that I wouldn't lose much low end and that it would get loud and sound musically good. My current box for my single CVR is 34 hz and I am …

So like it says how do you figure out the right measurments for 2 or more round or square port? and im asking because im thinking of doing a dual L port design for a 12" BTL. box will be tuned to 34 hz and will be 2.5 cu ft after displacement. so how do you figure out length and port area for each port? also if you know how ot do the circle ports it would be nice to know that as well. because i might end up going the aero port route.

Hey, I have a set of TC-7 woofers. Right now the box its in is 40x12x12 with independent chambers. Aero port out each chamber to the side 3'' in diameter and 13'' long. Its to long for what I need it now. So I was thinking making it 36x14x14. That way it would be short enough and then I could have the ports fire forwards too. Sound good? But I know these were designed for large sealed apps. however i cant find specs for that. Could someone just give me some dimentions to make a box? I dont need 3d plans and all that. Just something l x w x h because I dont know how much airspace for sealed. Thanks

My car audio team is holding a Car Audio competition in the town of Lodi. Here is the link http://www.team-bio.com/2nd_Annual_USACi_Sound_Off.htm This would be a nice little meet, for some people who want to come out and have a good ole' time. There will be a ton of cars, a ton of extremely nice cars, and its just alot of fun. Last year we held this event, we have around 50 cars. If you need any additional information let me, know Falout2guy __________________

just wanted to get some thoughts on bass box 6 pro..is it user friendly for a noob box builder like me and if so does n e one have it avail for a small fee

I found measurements for an enclosure for my 2 12 inch pioneer champ pros tsw3002d4. The box is tuned to 33 hz. I was just curious as to whether that would be good for my subs or too low? The amp I am using is a hifionics zeus 3000 watt zrx3000.1d. This will be my first box build so I want to be as clear as possible. I used RE audio calculator if that is any good.

I was wondering if you could have to ports on a enclosure and have each of them tuned differently, for example, one would be tuned to 30hz and the other to 35hz, would this enhance the sound or ruin it? I'm just curious.

I would like to know where I can get some MDF for a temporary/test enclosure I plan to build, I don't care how cheap or low in quality it is, since this will only be a test enclosure, I live in southern wisconsin, if you know of any stores here or any online shops that are cheap let me know. This will be for my 15" xcon for a temporary sealed enclosure for now, and after I get it in its new enclosure I will use this box for future testing purposes. i did do a quick search through the forums and I got zero results, kinda weird.

Ok guys here's the deal...... I've built two boxes so far this summer and have had problems with both of them. I need to know the best spot to put the port in a regular cab truck, preferably a Ford Ranger. First Box: This one got pretty loud but there was a ton of port noise. It is 1.1@33hz with a 3'' aeroport up-firing. The reason I ditched it was the port noise and I didn't like how it fit behind the seats....too deep at the top. New box: 1.1@33 again with a 3'' aeroport. Now it fires into the corner about 4'' away from the side panel. The output dropped rediculously and also the bass is just so flat sounding....it sounds horrible. What should I do? I'd appreciate he…

In the process of designing a box for the 15 Loaded BTL. Can I design an "L" slot port box to have a tuning freq of approx 40hz for comps...and then just put 1.5" thich MDF along one side of the port? Since calc's tell me that will bring me down to 32hz. So the port will be approx 6.5 inches wide for a 40hz tune and 5 inches wide for a 32hz. I'm just wondering because only the last 14inches or so will be 5 inches...the other 14ish inches (inside the box) will still be 6.5 inches. Will this screw with tuning...and will this raise or lower my ACTUAL tuning freq?

This will be my first wall build, I've been doing a lot of reading and looking at build logs. I should start by saying the plan is 2-3 (if I can fit 3) RE XXX 15's, on either a DC Audio 12k or Stetsom 14K. I think I'm going to go with Baltic Birch for weight and strength, I am seeing guys using 2 by 4 bracing, also seeing them use it for the back of the wall outside, what is the purpose? is it needed? what other ways would you strengthen the wall or face? the subs weigh 76lbs a piece. I was thinking 3-4 layer front face, double layer everywhere else, fully resin the box. How much bracing would you recommend? If you have pics or anything else you might recommend I'm open …

I have two Sony explode 10's I got last year; I have them in 1.3cuft each sealed; I am in the process of moving, all the big tools are in storage, so I can't build a new box. I have some scrap wood laying around, and I want to knock out a wall of the box and combine it with another slightly smaller enclosure and port it; I hate scrapping it together, but these are my killing time subs, I just play with them to try ideas; anybody have any tips on making junk subs drop lower? I am not after a ton of output, it's for a computer speaker setup; just want real low extension. I am looking to get it tuned to 24hz, with -plenty- of port; does anyone have any idea what kind of air…

Well, i saw something that made me think of this, so i made it, it is a box design, with 2 ports, that go out of the... front (same side as woorfer) and then come to a port directly above the woofer... its weird. lol any comments? lol

I bought a x12 and have made the reccomended ported box for it. I def sounds amazing when the windows are down in my truck it gets really low. But its not really as loud as i want and most of my music just dosnt go that low.. The other thing is i have a pair of harrison soundlab external subsonic filters... And a pair of right angle adapters from radioshack.. Could these be lowering the signal to the amp and decreasing my out put? Any help would be great. Iv heard you can fill the box a little to raise the tuning frequency.. Idk the sf are at 30hzbtw

Many times I have been asked: "What if I don't have a table saw, how can i still make a good box?" This video answers that question. Enjoy!

I discovered this on a Honda forum that someone had posted, the description of the box are in the web browsers little tag (this is how it is using firefox). They range from 1-2 subs, and 2 cf all the way to 4/5 cf. The tuning is a little high on a few of them from 35-37 hz, but theres some lower. I think this may help a few out, Sub Box Diagrams

Anyone tried this? http://www.splenduro.net/

If someone was going to build a sealed enclosure, and the woofer in question listed a box size of, say 0.75^3 to 1.5^3, how do you determine what size ^3 would best suit the woofer? Is that something that the tsparameter would tell you? Or, just build something in that size range and get equal results??? Just curious...

The guys at kicker said to tune to 39hz for 4x12" CVR's in a 9sq foot box. I don't see many people tuning much higher than 35hz though. So should I take their word for it and tune for 39hz or drop down to 35? This is my first ported box so, I'm somewhat at a loss.

Ok so my buddy is putting 2 old school JL W6 15's in his extended cab frontier. About how big should his box be, he wants to go sealed. And which way should the subs face? Towards the back of the seat or facing up??????
