SPL & SQ / Fabrication

18in Sx btw . Ok, I got 17.31cuft to mess wt here 43.5x27.5x25. The box is gonna be ported to idk 32 sounds like a good number. Suggestions? It will probably be dual chambered, wt the port on the end. Is that to big or not big enough is my question. It says it only needs 6cuft for sql, so i guess 8cuft for one sub isn't that bad.

i am planning on upgrading my system, but im still undecided if i should make it ported or a 4th order box, what will be the pros or cons of each, and what would be better it will be a blowthrough on a silverado, planning for 4 15" dc lvl 4 and a dc 5k, but right now i just want to build a box first, thanks

I wanna know if I could build a 4th order bandpass box for 4 12" subs in the trunk of my cavalier? I have a Soundstream Rubicon 2500D amp and a Kinetic1200 under the hood and a 2400 in the trunk. Thought about something sort of like this but, not too sure it would work with being such a small trunk...Just need some help tryin to figure out if I should do it or not. http://sketchup.google.com/3dwarehouse/details?mid=5362d8048075cdd16b752e7529d36aed[/media]

So I'm doing a build in my 2003 Dodge Dakota crew cab of 2 15" icons and would like to reinforce my roof. I'm getting 3/4-1" flex on one 10" incriminator I series and also headliner slap and it drives me crazy. I have a bulk pack of dynomat extreme I got for like 20 bucks. Would 3/8" MDF with kerfs And lots of pl then dynomat between headliner and wood be good? Just want to cut down roof flex and stop headliner flex. Any suggestions? I would rather not have to order stuff if possible as I'm tearing truck apart this weekend and shipping is slow Thanks

about 2 months ago I (with the help of M5) set up my first 2 way active system. Since I have lost the rear speakers and I have my sub crossed in at 50 htz with a 18db slope I now have a serious lack of sound from about 60 to 140 htz. The Bostons I had just would make this honorable noise at about 150 htz, just muddy and nasty. So i just got myself a pair of the new Rockford power components and STILL THE SAME PROBLEM what do I do??? I have already put dynamatt in the doors and on the back of the door skins. Do i have to take this thing 3 way in order to get some mid bass?

I've had some crappy 12's (MTX RoadThunder) and a 500 watt Bazooka amp since I was 16. I just got a new job and wanna go big. I have a friend who has a DD 10" (2510 I think) hitting 139 db on music with 700 watts. Even though I have more money to work with, I need to keep it as cheap as possible. I really want a 15 and however many watts it takes to get loud as fuck without blowing the sub. -I was looking at FI Btl but its a little high -I know DD is good -I don't know anything about Incriminator. -people have mentioned RE the only ones of these I've seen in action is DD. This is not an SPL build, just a daily driver that I want to be louder than the crap I have now. …

Just wanted to share this incredible build with you guys. 83 pages and still not finished. Attention to every detail. BERYLLIUM BMW 323ci. - CARSOUND.COM Forum Some pics so you know what you are going to find in the thread: And many many more beautiful stuff. Enjoy.

Have a 12" icon showing up soon and would like to get an enclosure ready for it. I've been using the bitpusher site to help me calculate the box. This is what I have so far Now I prefer to use a Single 4" precision port. I'm unsure how to calculate the entire port area I have with this setup. Reading through past threads and SSA's recommended 2.25 cu ft tuned in the low 30s. Also saw in a thread that for that size box I should aim for around 35 sq in of port. Pi * r * r doesn't calculate the length? Missing something somewhere maybe someone can help. Is a single 4" aero going to give me enough port area? Anything you see wrong here? One other thing. Going off the picture…

So, my daughters MECA Power Wheel got a broken port... So I decided to rebuild... The small sealed enclosure was practically free airing so I was looking at making a loading wall, but I don't know how to tune for just a loading wall which got confusing because it started coming out at a 6th order... So I started looking into 4th order, sealed one half, ported other. plenty of loading surface, as well as the output for the port to under the dash for the kick score. I have it as .35ft^3 sealed side (its a single 8 sealed enclosure is .25-.5ft^3) and ported side .68ft^3 with 2 2" aeros 10" long at 45hz. still fits on the back of the power wheels, and tuning a little higher f…

I have a ski port with a latch/door that folds down into the trunk to allow air to flow through. If its ported through the hatch, and otherwise sealed off from the cabin, would that yield higher spl would it be a waste of time/money? Im not looking for pure spl, I just thought this might let me keep my sq but make it a little louder. My current setup is a regular 2.5 cube box with a bunch of room around the top/side to get around to the back of the box and through the ski port. Here's my idea(s)..... And sorry that it looks like a third grader made these sketches.. its all i could do with ms paint.... side view of trunk shape with ski port door open/folded down loo…

im having one hell of a time trying to cut a couple 45's, do i really need them? i have some stuff to seal the edges, its not caulk though. what do i need to brace it. gonna sand it all since theres some excess glue all over the place, and my top wont fit right cause the port walls are a little taller, so i need to sand that down. and finally, will it be a problem since one sub is unloading on the port wall? comments, suggestions?

Well im swapping out my 2 SA10s each on an audiopipe APSM1300 for 1 SSA 10" XCON and i will be strapping both amps together to get ~2000w @ 2 ohms. It seems like I might get away with being able to use the same box and port length. The current box is 1.39ft^3 before displacement, making it 1.24ft^3 ... using the aero port calculator My exisiting 3" x 15" port will give me a tuning of ~30.8hz. Am i lucky and wont have to build a new box?

Aight guys, I have 10" american xfl sub a ported box tuned to 30hz in my sedan and I was thinking about switching it up and doing a 4th order bandpass box with a flared port tube shooting thru the rear deck. Also the rear deck will custom fiberglassed and molded to securely mount the port and speakers. Or should I just leave the ported box and fiberglass the rear deck with a vent for the bass to come thru. I'm just trying to eliminate having to keep the armrest down or having the seats folded down so that the bass isn't trapped in the trunk. Here's a video of a lexus with a 4th order bandpass box ported thru the rear deck thru the factory sub location http://www.caraudio.…

I have decided to go with Selenium ST350 Super Tweeter, and Selenium 6W4P 6" woofer. I will be running thes active and have a copule of questions about them. First question: one being will it sound ok to mount the woofer in the stock door, and the tweeter in the stock dash. I will have to modify the dash a little bit, since the hole right now is 4", and mounting of the tweeter is 4.25". Will it sound good with it located up there? Next question: Since this is my first active setup, I dont want it to sound like shit. So, how do you guys block the mid sound from going to your tweeters? and stop the real lows and real higs from going to the mids? I will be running a MB Qua…

So i just bought a new Craftsman plunge router, and i bought a 3/8s bit. Now is there a certain size bit i should use or what. Can someone tell me what they do. do i just have to add half of 3/8s to what ever size im cutting to get what im really cutting. Any help would help

Wassup fellas I built a box for a 18 btl but went with an aq hdc3 18 until Christmas. It is 8 ft3 at 30 hz. My problem is I think this box it too big for the hdc because anything above 40 hz sounds like trash but is a low end monster! also from 25 hz to 40 hz the excursion is the same! It's like the box is too big and it's acting like IB. Can some one help me out ha I want an ok topend instead of the junk I have know! Thanks

I started the cuts today, and want to put it together soon, but theres a few things i'm missing. I know i need to pilot the holes, but what size screws? I was thinking 1 5/8" Drywall screws. And for the glue.. should i just use regular carpenter glue/weldbond or something special? Also i read that MDF is porous, so should i seal it? and with what? And someone on a different forum mentioned to do seomthing different for the edges/corners.. .any idea what he meant? 1. 1 5/8" drywall screws? 2. Weldbond/carpenter glue or something else? 3. What kind of sealant if any? (recommendations?) 4. What should i seal edges with? I know its long but thanks for readin.

i bought a rockford fosgate t1500bd amp and it says its subsonic filter is at 28hz. im buying an Xcon 15 wich says to tune (optimal) 27-34hz going to try putting it in the optimal box size of 4 cubes. ive heard that 33hz is the best tuning frequency all around. i listen to all types of music and i want more sq than spl. also heard that your supposed to tune the box about 2hz higher than the subsonic filter. (gives me tuning of 30hz) is that true? why or why not? what should i tune my box to?

Alright heres what i have. 1 Kicker L7 15 Dual 2 Custom Ported Box 4.44 Cubic Feet Internal After Port And Sub Displacement Tuned To 34 Hz Kicker Kx1200.1-1400 Rms Alpine HeadUnit KnuKonceptz Kolossus Fleks 0/1 Gauge (About To Order) KnuKonceptz Krystal Klear Subwoofer Rca's (About To Order) Sub Is Firing Against The Rear And Port is On Passenger Side How Does That Setup Sound To You?

I want to do a install of 4 15s in trunk of grand prix. I will be building inside trunk. I just need help, and suggestions on designs. Let me know guys. 37" wide and with 16" tall, and roughly 50" long(from trunk opening to rear seats.

Whats up guys...Heres a box I finished up yesterday. It is a transmission line tuned around 31Hz. Right now there is an EHQS 12 (SVC 4 ohm) in there. Amp is a JBL CS200.1. Rated at ~200 watts at 4 ohms. As for how it sounds...FUKIN AWESOME. The tonality is a lot different from the 2.5 cu ft @ 30Hz box it the EHQS was in and output is a lot higher. This thing digs deep and has usable response down to 25Hz testing with sine waves...below that it unloads and doesn't have much output. It has a pretty flat response from 28 - 60Hz. I really love how it sounds. It's easy to tell when the EHQS is reaching its mechanical limits as I can hear it bottoming out but that is…

I'm building a box that's, according to my calculations: 1.9959 cubic ft (not including port and .12ft^3 sub displacement), with a port area of 28.75 square in, and port length of 33 in. This box should get me about 32-33 Hz. This box is for a single 12" SI Mag that's going to be powered by a Sundown SAE-1000D. Anyway, this is only my second box build, and my box building skills ain't nowhere close to most on this forum. But I'm wondering how some of my problems will effect the actual sound of the sub. My problems lie in the port, which runs through one side of the box, and continues around the back of the box. So, these are my problems with the port: 1. The port a…

I have two 10 inch subwoofer in a very big box. 4.4 cubic feet before displacement. I have one 4 inch Aero I made with pvc pipe but I get noise at low notes,tuning right now is 30hz. Was thinking to go with 6 inch tuned to 33hz.
