SPL & SQ / Fabrication

alrighhtttyy guys.... i got a tricky build that i need some help with. I'm putting two SPL-15s in the trunk of a 01 chrysler sebring sedan. The subs are going to front firing and im just going to keep the back seats down (when i put them up for people to sit in them i will just cut the subs off). The trunk is pretty flat and the box should be pretty easy to load in from the car with the seats folded down. I have L29 x W34 x H18 to work with, Im guessing both subs will be put in one chamber. Im open to either slot or tube ports, just need help coming up with a design. All of the parameters are here. I appreciate it alot and please help a fellow forumer out =]

I lined my box with fiber glass and mat, and it came out very bumpy, tried to smooth it out and did an ok job at removing some. My question is how smooth does it have to be, does it affect the over all sound pressure.

I've always designed the box with the port on the side, but now I need it in the middle (using 2 subs). I do know that when the port splits off the port width gets halved, but is the whole length of the port mean that each side is the port length? Let's say I have a box that is 6" wide and 30" long. When it splits off each side will have a width of 3", but does each side equal 30" long? Someone also told me that you add half of the width of the port to each side of the port length. So each length would actually be 33" long. I don't know why that would work though. When I design boxes I use torres and there's a box that says "# of common port walls". I put 2 in there, …

So after seeing the new box I built for my future DCON's (ordered over two weeks ago) a freind of mine has recruited me to build him a box for a single old school (2001) Kicker c12vr. He wants a SQ build and could care less about output. The only problem I am seeing is that I can'ft find any specs on the sub. The manual I found for it is a little light on the T/S parameters so winISD isn't too helpful. So my question is, If I run a standard 2cuft box tuned to 32hz(seems to be a standard), would that have a somewhat flat responce curve(ignoring cabin gain and all that)? It seems to be a tried and proven tuning so If I strive for that, and being that he is new into car aud…

hey, im going to be buying a VW rabbit in a couple months cause i got accepted to my #1 choice university!!!! i got a scholarship so now i have about 10 grand saved up plus i'll take out a student loan and im gettin paid to go to school (1600 bucks a month). I currently have a Fi Q18 tuned to 28-30 hz, and i hit 145.2 on my first try with some music. Im looking for some help on deciding what the best setup would be for a hatchback. Im thinking 2 12" BTLs with about 5000 watts. im really excited to get this project goin. my goal is to break the 150 mark but music is what the stereo will play, no farting. any help is appreciated!!!! thanks

I have a crown xls 1000, puts out 1100 watts bridged, had two 15s in room, sold them. Just ordered a 12" Icon. I would like to build a ported Enclosure. Can anyone help?

do aero ports have to be straight or can they have an elbow somewhere in between .. also when designing a box with an aeroport does it need 90 on the edges ?

i can't find it anywhere, where do you all buy your polyfill?

Hello, I was wondering whether it was possible to use two different port length on a same box: For example I need 31.5 inch of port length total for 2 x 3" round ports. Can I make one 14" and the other 17.5"??? It's just that it is quite difficult for me to fit those two ports inside the box, outside would be possible but aestethically wouldn't be good. Thanks guyz, Kelvin

This is a goal to reach 150db tuned for a daily driver. I've been doin some measurements and have came up with a box design that has me smiling and this will be the last box i will build for the car... unless i downgrade later. This is my last attempt to try and reach 150db with a daily tuned setup and i'm crossin my fingers because this is only with 2 15s and 4,400w of power. Here is the wild design- Remove back seats, where back seat was, install a wall there sealed off from the hatch area. Now, i have 33" of depth from this wall to the back of the front seats. The box design would consist of 2 15s ported facing toward the wall. There is an 8" gap from the front baffle …

Yes, i've used a table saw before, before anyone asks lol. But never for a box with mdf. The table saws i've used have always been pretty big, like shop table saws. I recently borrowed a 10" table saw from a buddy who builds boxes with it, but it's small as hell. It's really small, especially for the box i'm making (the biggest sides are 39.5"x21"). I even put tables on two sides, to help support the wood as it goes along the blade. I used a circular saw to make the mdf as small as possible for the saw, cutting the 4x8 in (about) half. Everytime i take a piece across, it kicksback pretty bad. Now i know i'm not the first person to use a small table saw for a big project,…

Would someone be so kind to briefly walk me thru the process of how to properly secure a fiberglassed roof? Basically.. i'll take the headliner down.. build a wall in my car, then from the B pillar on forward, that will be fiberglassed, ok? this is where i get lost.... How do i attach the fiberglass mold to the vehicle so i could remove it again if i needed to?

I ordered 2 18 zcons Thursday and today I did some measurements and got 48w 25h 32d all inches and that's with my back seat out of my ext cab sierra I listen to mainly rap with a little bit of everything I was thinking around 32 htz for tuning there going to be on a saz 5000 I'm sorry if I forgot to add anything

Ok I got my new install done which consist of 2 15 xcons facing cabin in a sealed box, ran off a crescendo BC 3500. My question is will it be a significant gain in output if I go with a ported box instead. Only reason we went sealed was shortage in trunk space given space we had enough for opt sealed enclosure. Any info?

Alright, so I'm planning a build for my S10 reg cab, and need help designing the box. It's going to be 2 SA-10's in a 2 cu. ft box net, ported, tuned to 33-35 Hz. Also powered by a SAZ-1500. My max dimensions are 50"L, 22"H, 9"D bottom, 5"D top. I made up a box using the torres box calculator, but I was having problems with the port. I'm planning on using aeroports, but they were needing to be too long for that tuning in a small box. Not sure what diameter, and how many I would need. If anyone can help me out I'd appreciate it!

i am building a sub box for a m3. it will be in the spare tire well. the box size that i am shooting for is about 0.5cu ft after sub and port. the cubes i am using i got for sundown audio. i am just looking for a nice sq sound. i am not sure where to tune it but my best guess would be 35hz. i am looking to go ported and need the port size and how long the port should be. i'm only running about 300watts.

I need a good set of box plans drawn up i have no problem building them.....just a noob at designing them i have all the t/s parameters ect... im really looking for a burp box i alreay have a daily box that does decent numbers on the TL ....just need something designed for the TL....Let me know if you can help me out. Thanks....

I'm looking at building a new box for my SSD. 9 cubic feet is a bit much in my jeep Pretty straightforward question. Only thing i really know of to design a box is the RE calculator. Whats the best though ?

i dont know if this is the right section but i was wondering whats a good filler to cover screw holes on the outside of an enclosure before painting the enclosure? i made a box out of birch. i want to have a high gloss finish after i paint it with no screws showing. thanks

Hello, I am building a box for a friend and I had my MDF all ready to cut, measured out panels and everything and he calls and tells me that he want an aeroported box. I have searched and read different things in this section and after figuring out slot is actually a lot more different than aero ported, I just don't get it. So, I have come for some box designing help. Dimensions: Depth: 16 Height: 16 Width: 40 It is for an Fi X 12. Was hoping for 2.0ft^3 at 32hz I really just need to know how many flared aeroports I would need with no port noise. Diameter and Length of the aeroport would be nice. Thanks in advanced, Jay

aight. i have 3 12" california profiles. i have 3 custom 1/2 mdf wood boxes. there in a ranger single cab. i have 2 behind the seats and one where the center floor console/ cup holders were. i dont have the exact specs but there .40-.50 cu. ft. of airspace for each. the subs need 1.25 cu. ft. of airspace, but there just temporary till i get sum new ones. well my question is..they really dont have any excursion at all. they really bump but dont really move. i figured its cuz of the super small boxes. and probally cuz i didn't put any poly fill in em.or maybe cuz there low rated subs, they have like 50 rms and 350 watts peak but if i get sum 12" kicker cvr's or even some sh…

Metered with SPL-LAB same song and I got a reading of 160.1 @36 hz in the port and 146 @48 hz in the cabin. Does this sound right for the difference in frequency readings? Or is the deeper bass getting trapped in the trunk? Let me know what you guys think, thanks.

picked up a pair of 12" iCons and this is the box I plan to build. I was wondering what you guys think. This is the first time I have run anything other than a single 15" or a single 18" so I want ot get opinions before I build it. 4.8ft^3 net air space (5.12ft^3 gross .16ft^3 displacement per sub) tuning 32hz-33hz 72.5in^2 port area
