SPL & SQ / Fabrication

Hey guyz.. Does anyone know of somebody that does good door panels around the san antonio area or somewhere near by?

well tomorrow my third rl-p 18 should be here, so now i need to start doing some box planning. i have an isuzu rodeo (suv) with the back seats ripped out. im going to use the whole back portion to build the box. its not going ot be a wall though. my question is what size and tuning should i do for all three? i see the recomended 5 cubes at 27 hz for one, but im not sure if it would change for all three. by that i mean, would the optimal size be 15 cubes at 27 hz? maybe im overthinking it but it seems ike it would change due to there being multiple drivers in the same box. also, i know i can fit the box in my suv, but porting it back may not work. my back window angles in …

Hey guys, I have been into car audio for about 5 years now and I believe I am fully ready to to do what I would consider a high end setup. I currently have a 2002 Hyundai XG350L with my 2 mtx 4500's, alpine amp, and rockford fosgate p1 components and 2 ways in the rear deck, with a P300.2 powering them. I am getting ready to move into my parents new house within the next month and will have a full size garage to work in. This will give me the place to let my mind expand and come up with ideas. I have been looking around at some new subs, I Have a couple of ideas in mind but am open to any suggestions as I havn't heard any system bigger then 2 cvx's on a JL 1000. I a…

I'm working on a box design for a single ported SA-12. I looked at the Sketchup design they have for a 1-12 ported, and I came up with this for my vehicle. It seems pretty dead on. Is the 13.5" x 2" port too narrow? The one in the Sketchup is 14" x 2" so I figure it's good. Thanks.

ok so i got a 2001 4runner and i need a box for a 10 downt know how much watts or even what sub yet but would slot ported be my best bet for a daily want to hit all notes but 33 or 34 hertz will be my bottom end what i want any help would be appreciated

due to the complexity of the sides of my box, its going to be kind of hard to build a slot port on the top of the box. i was thinking, instead of a slot port, should i do like 4 6" aero's? (or whatever i need to get the right amount of port area) which leads me to my questions. -if you have 200 (example) sq in of port area, with a slot port, if you switch to aeros, do you still need a ton of aero's to get 200 sq in? or does less aeros equal out to the larger port area of a slot port? -aero ports in a wall. how will this work? i know one con is i dont get the natural bracing a slot port would provide, but ill deal with that, and add some extra bracing. -difference in sound…

2 part question, lol. 1). I'll be getting an '05 Chevy crewcab next week sometime, and I was wondering if it's possible to get 2.5 cubes anywhere from behind/under the rear seat? 2). If not, I may consider a blow through. The problem is I dont want to cut a big hole. What effect on tuning would building a box like this? Thx for any/all help you guys can give. :clap:

so i need the calculations needed to figure out my problem(or the answers) with this build want it to be a true not done on a online cal.(unless one will give true port cal within a 2hz of needed frequency) box 20h*48*40*d using 6in PVC? thanks to all that have any input for me. its 4 15s and want to tune between 30 to 34hz.

heres my box measurements 5.339 cubic feet i want to use areo ports to tune this box to 30 Hz I want to use maybe 2 - 4 inch areos or what ever you guys think would be the best to use please include the measurement of the flares too please break down the measurements to the areos ill get them for parts express. thanks guys, Bill. ps I need to know asap cause i have the box built its ready to go.

I have some final questions for my box build. I wanted to use two 8" aero ports that i was going to run through the rear deck to the box. Both ports will have to be 32 inches long which is two long. If i switch to two 6" will that be enough port area for two z 15's? I need to switch to a smaller diameter ports so they will be shorter. What are the pros/cons of doing this?

whats up yall i just finished the box today for my custom forevrbumpn kevlar 12". box is 2.49 cubes after displacements and tuned to 33.2hz on paper. pics you say?? and heres some of the sub...

Ok, where do you guys buy your carpet for your builds? I want some really good carpet that doesnt have a bunch of crap on the back and is easy to use. I will be carpeting parts of my box, trim work and false floor. I've always used 3M 77 glue but I saw where some folks were spraying on that contact cement stuff. There really isnt much difference in the 2 right? I was checking out a lot of Thumper's enclosure builds and that guy did really good work. His forum looks like it hasnt been active in a while. Any idea what he uses? Thanks for any help. TST

After doing the math i come up with a .825 cubic foot enclosure which doesn't seem to leave me with room for ports. Can someone help me out here please? What should my internal volume be? I used the box calculator at the12volt.com, is there a different calculator I should be using? Thank You to anyone who can help me.

im about to trade for 2 SSD 18's just to mess with for a bit. so im planning on running about 11.5 cu ft at 35 hz, but gonna make interchangable ports to play with different frequencies. so should i port it forward, or up. subs are gonna be facing forward in a 01 dodge ram ex cab BTW

Just trying to figure all of this out. One site says figure your tuning dependant on port length, others say by width and height of port (square inches of port area). So what's the verdict? I have 2 SSA Xcon 18's wanting them in a 6.5 cuft (each) box tuned at 31 hz. Also, what is the difference sound quality and SPL wise between having one large port or a seperate port for each sub?

So I have two 21" dp's and I am wondering, what is a good rule of thumb for port area on a spl box? As far as square inches per cubic ft? I have never done a spl setup. And I am planing on doing two slot ports for spl and plugging one for daily use. And would 10 square inches per cube too small for daily beating? Also may try something like four areos to keep down on internal space.

Okay so, I got my designs, and lowes completly messed up all the cuts, so I have to take it back and complain and hope that they give me new wood or something..... So in the meantime, I just "sketched" up this box. Here is a pic here is the google sketchup file http://files.filefront.com/fibtl18skp/;13080625;/fileinfo.html for anyone who wants it Let me know what you all think! (I didn't make up the specs for this, a help from another member on this site did, I just drew it)

I just purchased a used 2007 Lexus ES350 which has a factory 10" subwoofer on the rear deck. It accomplishes some midbass, but just doesn't fill the cabin like I'd hoped. I want to install a Sundown SA-12 along with my existing Rockford 1000bd (I won't have it turned all the way up most likely). While I realize the RF Amp probably isn't best at a SQ install, I'm hoping the Sundown can fit the bill. My question is: Is it possible to make a box that can fire through the fold down armrest in the rear seat or up through the deck? How complex would something like this be in order to eliminate the loss or sludgy sound of bass firing into the trunk? My main reason is to try and…

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

ok so im hopefully gonna get pix tomorrow and start my new build log. ill also get measurements of my hatch area tomorrow. i've got my 4ft3 box tuned at 33hz in my 93 lx mustang hatch right now and its just to big. it currently sets taking up half my backseat(folded down) and a 1/3 of the hatch area. reason for this is it wont slide back anymore in the hatch area cause the box hits rear window. saz-1500 is temporarely mounted to the backseat right behind front seats. so i need help on how to face my sub and port to get the max. loudness and airflow from my rf power hx2 15 while still being able to use my backseat for its intended purpose. also im set on 33hz for port tuni…

sub in question here is a xcon 15 this is my first time using this or any sub enclosure design software when i put in the qts, qms and qes parameters this is what happens: Help a noob out!

Its been a while since ive been on here... but i need some help... I'm building an enclosure for my new car (02' focus ZTS) which will house 4 10" woofers firing towards the rear of the car at a slight angle with the deck lid.. (ie 35-45*) question one... is this going to cause a lot of cancelation? question two... i want to build a seperate air chamber to fit the spare tire well... and connect the two chambers to increase my overall air space... will doing that actually do anything for my airspace considering for now... the box is sealed? thanks for any help -AcId-

I am pretty serious about doing a blowthrough to my F-150 in the next few months. I am pretty settled on 2 18"s on 4000 watts (will be more with upgrades in the future.) I was thinking of a 4th order bandpass box for them but I want to be loud on low hertz (like around 30-35). How can I accomplish this? Also, what would be better: 2 18" or 4 15" all on 4000 watts? Like I said, I want to be loud but hit low.

Im trying to make an enclosure for a single sa 12 but the only wood they sell out here is 18 mm thick mdf, I'm wondering how to compensate this into my cut sizes for the box I wanna build I wanna do 15 h x 17d x 22w with the port being 2" wide and tuned to 32 hertz any suggestions?
