SPL & SQ / Fabrication

Hey guys just looking for a little input here I have been doing some measuring and test fitting cardboard templates to see what I can fit behind my seats without having to loss a lot of leg room. I came up with this set up. Dimensions 13”H x 20”W x 5”depth1 x 8.5”depth2, with 3/4 MDF it gives me .646 ft3. The Sundown SA-10 specs say it will do fine in a sealed enclose at .5 ft3 so after displacement I should be right on track with .546 ft3. My only real concern here is the mounting depth at 6” I should be in the clear right?

hi all i recently purchased a fi q 18 to go in my 95 4 door explorer and now i need to come up with the plans for the box so i can start building. my maximum dimensions for the box are 40 wide by 40 deep by 22 high. i am a some what skill full carpenter but i need help in the tunning area. also if anyone has a similar setup to what i will have and still has the plans lying around i would greatly appreciate it or if someone could use or tell me where i can find a box calculator to spec out this box that would also be greatly appreciated. oh and lastly i am open to using a t line but would need the plans to build one. …

If I can get enough interest I will be doing an IASCA judge training April 11th and 12th in Santa Rosa. I need to get judges up there before I can have a good amount of shows. If any of you are interested in attending a judge training in Santa Rosa please email me at [email protected]. The training is $100 for both days. It includes a full year of membership in IASCA (which is normally $60). Even if you just want to compete the judge training is a great way to get a full understanding of the IASCA rules. When you consider that you get the membership it boils down to $40 for 2 days of SQ instruction. Schedule is: April 11th 9am-5pm -IASCA philosophy -IASCA classes and …

I need help to build a box for one 12" Fi Q in the back of my regular cab GMC truck. I don't want to compromise sound quality and i do want it to get loud. What i was thinking of doing is fiberglassing the bottom floor behind the passenger seat where a box would normally go and use MDF for the front, sides and top. I 'm not the best at 'glassing, it works but isn't pretty. I'm trying to get there recommended size of 1.2 - 1.3 cubic feet. Any ideas to start??? If any one has any ideas please let me know i am open for suggestions. Thanks in advance I want to run a 12" Q and a Sundown Audio SAZ-1500D.

I am designing a slot ported box for a bl15 fully loaded. I am looking for 4.18ft^3(4.0 after speaker displacement) @ 32hz. I just need to make sure I got my measurements right. The dimensions(external) are (H)19.5 x (W)45 x (D)14.5. The port is (H)18 x (W)4 x (L)38. Am I right? And is 72in of port area to much? Oh yeah 3/4 mdf is the wood I'll be using.

Whats the best agent to apply ur carpet to your enclouse?

What % can an enclosure be off on recomended net cubes. I thought I remembered reading 10% somewhere. It's a daily driver.

Could I get the same output if I use aero tubes on my box instead of a regular port? I want to get a 9cuft box for the new 15" BLs. Would the aero tubes make the gross area of the box smaller because I want the box as small as possible but still have about 9cuft of area after displacements?

So I used to run my Fi SSD 18 in a 9cuft box tuned to 32hz (or close, it was my first box build and I had some hard times with it). I liked how it sounded, though it was on the high end as far as box recommendations go for an SSD 18. The thing with the box was that it suffered slight water damage and aesthetically wasn't as pleasing as I preferred. I was looking to either paint it or put some sort of vinyl or something over it to improve its looks, but never got around to it. Another thing that was annoying about the box was how LARGE it was lol. It was initially designed for my room, but was moved out to my Jeep Cherokee. I wanted to keep the back seats up, so the only w…

Hi, just wanted to ask which box would be best for my space and will do the Best Output, I want a box it with a maximum of 4 cubic int. feet. I am going to buy 2 12'' SSA Xcon and I will like to know which type of box (Ported or Sealed) is best recommended for my space and my needs... Thank you.

does it matter what side of an enclosure your port is located on ? my sub is mounted in a up fire position on one end and I WOULD LIKE TO no if it makes a difference if my port goes out the other end of my box just opposite of my sub basically firing at the door

Ok, i just bought 2 Fi Q 15's with BP Power and a AQ2200D amp for my truck. I have a 2000 ext. cab dodge dakota and am looking for some enclosure help. I currently have an idea for a certain ported wedge design with my amps fixed to the bottom but it is only 6.2 cu.ft. net with 78 sq.in of port. A similiar design can be found here: http://mobile.jlaudio.com/gallery/detail.php?vehicle_id=1095. If anyone has a design in mind, and would like to show it, I can be emailed at [email protected]. Any input is welcome. Thanks in advance for your input.

Just got about everything I need to start the build, so I am starting to design the enclosure. Did some searching on the site and haven't really found the answer to a couple of my questions, so I will post them up here. First the box is going to be for 4 RE SE12's powered by 2 SAZ-1500D's strapped. I have the 1/0 for power and runs, and am picking up 2 new batts for the back tomorrow. This all going in the Suburban. Box size ideally is going to be 8cu.ft. with around 128-157cu.in. for port. Will see if I can fit aero's if not I'll do a slot port and this is for daily. I have built and tried 3 different boxes so far. All peaked between 40-45hz, one box being 2 1…

Im changing my set up.. i only had my 2 10" Qs for a couple months but they arent loud enough for me anymore. I have an 04 super crew F150 and im taking the center seat out of the back seat and im gonna center console 2 12" BTLs. maybe if i can fit it 2 15" BTLs id like to keep it a wood enclosure to keep the cost down. Anyone have any ideas for how to get them to fit and have the airspace they need? and then ports?

Which port, on average, is after for spl? What is the major goods and bads of each? I will be using 1 maybe 2 dc xl 12s and then later 3 level 2 8s or sa-8s.

Im designing a box to go under the rear seats of my Ford F150 but i dont have any designing programs i have the specs for the biggest sealed box that i can fit but i want to design a ported box tuned to 33 Hz for a 10" Fi Bl. If anyone can design a box using these specs it would help me out alot! and let me know how many cuft the box is. thanks!

I am getting ready to do a blowthrough in my truck. The subs I am planning on using are 4 Audioque hdc3 18's. The dimensions are 50x17.5x77 inches. I will be running them off of two IA 40.1's strapped. I have built several boxes but never a blowthrough. I have heard that bandpass is the best way to go when doing a blowthrough...is this true? Anyway is there anyone who can design me an enclosure for this setup? I will pay of course just let me know.

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

some one give me a little feed back! ive always thought it was best to give each sub its own chamber then slot port in the middle? lately ive seen alot of boxes where the speakers are pretty much sharing one chamber and L-ported towards the drivers side firing back, is this more effiecient sounding? or is this done so the box can fit better? i have a 2002 accord and i want this setup to be good DAILY. dnt care so much for SQ but more so SPL. meaning SPL to the ear ill doubt i ever see a meter. THANKS FOR ANYTHING GUYS

My car is a dodge charger,my system will consist of 2 12"subwoofers maybe "maybe 15 inch woofers if they fit.my two extra batteries can go in my spare tire area and my amp can be mounted on back of my seat.my woofers will be running off a saz3500,my question is will my setup get way luder if my box ports through the rear deck?or shold i do a box toward the rear of my car with the ports on the side?i dont mind doing a port in my rear deck if its gonna get alot louder that way..

I have 40"x 15 x 25 to work with. Would this be sufficient for either 4 sa-8 v2's or a single dc lvl 6 18" assuming it'll fit physically. Its going in a 2005 civic sedan with a 220-250amp alt, 2-4 xs d31's and probably a stetsom 7k or similar. I would like to have itforward fire into the cabin while being sealed from the trunk.

I want to go with a 4" aero for this temporary build. I am going to go 24x13x13 with 4" aero at 14.5/8ths long. Tuning will be around 35hz? Volume should be 1.5ish after displacement?

I am tryin to work out a box plan for 2 18" Fi Q's, the box i am plannin will really be 2 seperate boxes. 1 for each 18 then bolted togather, then trim paneled in to look like 1 box. Doing 2 boxes to make it easier to pull the boxes in and out(I am a 1 man build crew) of the van(2000 Gmc safari). Here is what i came up with from RE's web site. Each box will be 25" wide by 34" inches deep by 21" tall wood thickness will be 3/4 inch mdf, port width will be 4.5 port height will be 19.5 and the lenght will be 28.75 to give me a box that is tuned at 28.18Hrz and gives me 6.766 ft of airpace. Do you guy think this box will be ok for everyday driving, I am looking for good …

my question is, should there be any nocitable difference if i switch boxes. it will be for 2 10" chaos on a t1500-1bd my current box is a 1.8 cubic feet tuned to 32hz and will build a bigger box, a 2.5 cubic feet tuned to 33hz all this measurements are net volume, and the bigger box has a bigger port thanks
