SPL & SQ / Fabrication

this is my plan. im building a box that has 4 nightshade 15s. i designed the box on a 3d program to scale. the box is 19.5 cubes. the port is 7inches wide and 38.5 inches tall. that gives me 269.5^2 inches of port area and i need 12-16^2 inches of port area for each cube of airspace. so ill make the port area requirement. the box is tuned to 30hz. i will also be having all the walls 1.5inches thick. everything will be liguid nailed and screwed together.what you guys think? i cant seem to get the pictures to upload. i dont know how to get it from google sketchup to a image hosting site. any help with this?

I'm going to attempt fiberglassing for the first time. I'm going to make some kick pods for 6.5" Midbass and Softdome Tweets. I've read just about every forum and "How To" I can find so I'm pretty sure I know what I'm in for, but the one thing I haven't been able to find is how much chopped mat do I need to buy. I'm going to order from US Composites and they have 3/4, 1 1/5 and 2 oz chopped mat. Which size is most commonly used and how many yards would be adequate? I'm sure I'll need some extra just incase I do some beginners f*ck ups Thanks, Bob.

On the Termlab im hitting a 144.3 sealed up at the dash with a sweep. its in a trunked cavalier. i just want to know if i can get that score a little bit higher? would holding the trunk lid, sunroof, or doors down during a run help? would more room for air to get into the cabin help? does subwoofer box placement help, meaning how far away from the trunk lid it is, also how about rear seat folded down half way help? how about front seat positions? kind of just trying to get as much of an edge as i can. with the 144.3 run it was all set up for daily driving, not much tuning done at all, as in i didnt play with box position, or seat position or anything like that. i just k…

Well, i didnt think this was going to end up happening but i actually saw an Fi BTL N2 18" For $400 in my city. I was previously going to get a 15" Fi Q or BL which was going to cost me $400 shipped anyways so i cant give up this opportunity. Now in the quest for less trunk rattle, i wanted to fire my subwoofers forward into the cabin, BUT i dont have foldable seats. OhJay gave me a good idea. Use external aeroports that go through the rear deck where the 6x9 speakers go. I thought it was a great idea, something a bit different. Now i was wondering if any of you could make it happen. Iv got probably 19 inches maximum of height, probably about 40 inches of width. I…

alright so I will start building a sub box pretty soon but I have an issue, there is a metal brace on the floor of my car going from one side to the other. can I work around it? or does the box have to be flat one all sides?

ok my friend will build me a box in his wood shop but i need to get him plans. SI 15 MAG, ported. what do you think of the aeroports? is it worth it for only $25 extra? most people use 2 of them at $12 each. power will be a hifonics ZEUS 1000D 1000@1ohm it is a lexus 2002 es300. should be the same as the new camrey. people have put 2 15 in there before with a almsot bent box. i only need 1. the red strap is what i will be using to hold the sub in place, i would also love there to be ehough room to put my trunk battey next to the box. it is 6.5 inches wide demetions are THANKS FOR ALL THE HELP I AM FINALLY BUYING A SUB TO FINISH MY AUDIO SYSTEM AFTER 2 YEARS!!!!!

About to start the new enclosure for my 2 zcon 12s. It will be a trunk wall. I will be trying a 10 inch round port this time. I'm wondering how many cubic feet you guys think I should aim for with the new enclosure? ? Will have an aq3500 at .5 on them but Will be adding another 3500 as soon as I can find another. . Going to be tuning around 33-34. any suggestions?

Hey guys just need some advice here. I have a 98 Dodge Ram Extended cab and plan to install a BTL 18 in the back. The seat will come out and I have ample room for enclosure. I just want to know if anyone else has done this kind of install in a similar truck and I basically want to know if the FI specs for box will be the best, maybe someone else has found something that works better. I have an Exile X2400.1 that is going to push it. I listen to mainly rap music and I want that sucker to pound. I already performed big 3 upgrade and have cap ready to go, my truck is diesel so I have 2 batteries already. I figured FI's specs for enclosure are on the money just looking to see…

I Recently Talked to Chad Kyupers Drivers Start Shipping a week from today. While talking to him i mentioned 6cuft@29Hz, he said he had a guy do 4.5 at 30Hz and its output was INSANE with only 800w. he said 6@29 with 1200w should wang hard so im down to 2 enclosure options, both with equal port area (77sqin) only one iwth 2 ports and one with one. originally i though there was going to be no way to get the ports on the same plain as the driver, so i designed a side firing enclosure and the port a straight shot. then i came up with the idea to get the port on the same plain... see image below http://i11.photobucket.com/albums/a167/CBFryman2/avatest.bmp the bottom thing…

I might be doing an install with a clarion DRZ9255 with a active setup on the HAT L1's .. wondering how accurate the built in crossover is on the clarion if anyone here has used it in this fashion

where did it go!?!?!?

Way late but as promised here are a few pics, sorry it took so long and even if you don't know it all you guys on the forum have helped me in some way or another. The idea was to obviously keep a sub inside the car (like my 8's that were in there before) those of you who know BMW trunks understand why. Keeping it stealth was a main focus hence the flat black paint it really blends it into the car. Any and all comments are welcome, keep in mind I designed it to be way stiff, sound great, and astetics came in last. I estimate that it is around 1.2 net after polyfill. I set it on top of my 1.5 cu ft net box and it was fairly close. Later, b

Okay, from what ive read over the past few weeks ive decided that i want to go with an active frontstage. My DEH-7800MP is capable of this from what ive read. I plan on glassing the front doors to accept a well acoustically matched woofer and tweeter combo, i was hoping someone here could give me some suggestions on what woofer and tweeter to use so that i have little flatspots in my sound. Also for reference i hate harsh pingy tweeters, i don't particularly like all my highs to sound like crashing symbols! lol.... With switching to an active front stage this also means i will be completely losing my rear audio am i correct? Thats the only thing ive been confused about! T…

Today I purchased 2 kicker L7 12s and a rockford fosgate prime 1200. Can someone help me with a design for my 1998 s10 extended cab, my max dimensions are 46" wide, 22" tall, and 13.5" deep would like it tuned @ 33 Hz. Any help is appreciated

As it says above. I dont plan on taking 2nd again this year. i will post pic. soon. somethings involved are a credit card that is pretty close to maxed out at the moment to add alot MORE POWER and maybe more subs just have to wait and see

so i still havent gotten around to doing a new box for my bro's L7. but im thinking about trying something alittle different. he basicly only wants spl so im thinking about trying a wall... i have to build the box in the trunk anyways so might aswell try something new. its a mercury sable by the way. im thinking 6 cubes net design from the manual or do a tuning around 34hz...? we are prepared to deaden the rear deck, etc. will there be more output from a wall in this car or would it be a waist of time? if we did the 6 without the wall there wont be much of a trunk left anyways... and im sure we can seal the trunk off from the rest of the car effectively.

what tunning should i use for my box , i need it for LSQ should i do, 25-30-35 or 40 ??

So i know you can tune a box to a certain hz and specific dimensions for a squared ported/sealed box But, Is it at all possible to calculate and tune a fiberglass piece that you make to mount your subs on the side of the car or anything? ive read many tutorials on how to fiberglass but nothing really mentions anything about proper dimensions and what not for a sub. so am i sacrificing quality and proper sound for looks by fiberglassing?

So i've been doing some reading and I'd like to seal the rear vents in my '06 tahoe. I've never worked with sound dampener before but I think that's the best route to go..Any suggestions as to what I need to buy or the best way to do this? Pic of someone elses truck an the vents in question:

I have a FI SSD 15. (bp power, flat coil) I currently have it in a 18x18x38 box tuned to 34-36hz somewhere in there. aprox 4 cubes. Im thinking of building a new box, what should i tune it to, and how many cubes? i find my box has a slight bit of port noise because there are no 45s and it doesnt go as quite low as i want it to. Iv heard other ssd 15's hit harder than mine, so im trying to squeeze every thing i can out of the sub. also with the box the way it is now, what should my Amp be set at? Lowpass and subsonic? If it matters: its going in a crew cab GMC, powered by a AQ1200. thanks, in advance all help is appreciated

I'm going to be putting together a new box this weekend for a 10'' BL in my reg cab ranger. First off, the box will be 1.6@36-37 with (2) 3'' aeroports (Fi recommends 1.25). Will I run into any problems with having the box larger than optimal size? How should I put my ports? Here's the space I'm working with: Option 1: Option 2: Option 3:

So i made a 4th order bandPass for 2 obsidian 12s out of birch. I started sanding the enclosure and filled it all the screw holes sanded all those spots with 60/120/220 grit sand paper everythings smooth(so i thought) i started painting the enclosure with kryole dual primer and paint(spray can) i thought it would be good to use that lol well im pretty stupid to think that was gonna work great. The corners are very dull along wIth the edges that are sanded and the top and sides are super shiny and it looks like shit. Whats a good paint to use to paint birch with and have it turn out super glossy. My goal is to have it very glossy and not be able to see with the edges meet …
