  1. Dont use 3" pvc for your port unless you use multiple ports. I used the Alpine spec for a 3" port for my 10" Type R and it made a hell of a lot of port noise. I changed it to a 4" round pvc port and fixed the problem. How many cubes is your box gross, internal dimensions and is this for the 2 subs in your sig?

    I have a box that i made for my physics project. http://www.stevemeadedesigns.com/board/ind...showtopic=64923 I have 3 inch tubes in either side right now but i want to lower the tuning and i know that i need a 6" long tube to get it there. I dont have any port noise. It is a bandpass enclosure and the tube is in the front chamber. The ported chamber is 1.8 cubes and the sealed chamber is 1.5 cubes. Each subwoofer has its own chamber. So you dont think that using straight up like plumbing PVC pipe would work?

  2. Ok so i have my box finished and installed but my tuning is way way too high. it is tuned at 41 hz. I know that to get it down to 36 hz (where i want it) i need a 6" long 3" diameter port tube. I cant find them anywhere i can only find them in like 4" or 4.5" lengths. My question: can i use PVC pipe for a port tube? I have access to some 3" pvc pipe and could easily get some of it.

  3. BTW, if i was having my kid in high school (which I have a freshman and a Senior) I would want them paying off their education by not dabbling with car audio or talking about bass, as there is real no point or benefit

    laser, IR, solar, thermal, wind generated electricity is what needs focused on as it is the modern times and the future

    I understand what you are saying about the future and the different technologies. I should look into that, i would like to tie it into car audio though. Im not planning on going into car audio after my engineering degree i just would like to do it on the side. Wind energy is huge in my county we have over 400 wind turbines.

  4. what was the point of the video

    you made excuses all the way through it...

    do something cutting edge or with the times. try showing perpetual motion :)

    actually do a solar project or a wind project generating electricity

    I actually have a great one but unfortunately patents come to play as I have yet to do it, but I could be rich and shameless and with it you could possibly drive from new york to Cali with 1 gallon of gas, and at speeds of up to 300 mph... seriously

    non nuc either

    People just wanted to see the box playing, i didnt know what else to say. times? what did you mean by that? U an engineer?

  5. Aight, and so you're saying you tried to do it and didn't make a copy of it?!?! so the origonal no longer exist?!?!

    Please say no!

    and BWT I have that scoshe wiring to, did you get it from wal mart with the half farad capacitor?

    No i didnt make a copy of it but it will take me a whole like ten minutes to render another animation wheni get back to school. No i got the scoshe wiring from crutchfield when i ordered all of my stuff last year. i have two 8 gauges kits blue power clear ground.

  6. Ok I just started 2nd semester my junior year high school. My second semester in Advanced Physics. First semester I dabled in the acoustical side of a box for my independent project. Click here to view the post. http://www.stevemeadedesigns.com/board/ind...=64923&st=0. This semester i have to do an electronics kind of thing. So what should I do? Maybe like a sensor for some interior LED's to make them flash to the bass or something small like that. I am open to any and all suggestions though and I appreciate any suggestions. Also, no videos yet from the box. I havent made it to the store yet to buy some caulking. The plexi window that is on the top and slanted face is letting out too much air. When I put some stuff in the path it almost doubled the volume so yes the box works but not 100% yet. I need caulk.

    Edit: Part about vids and box.

    Edit 2: I plan on majoring in eletrical engineering with a minor in acoustical engineering so even if you might find it challenging for a junior in high school toss it up becuase I would love a challenge. I do have a base of understanding with circuits and electronics, but by no means am I saying that I know everything. I know i have a metric ton to learn.

    I know im qouting myself but instead of a new thread I thought i would add to this. What about a dB meter? Is there anything any of you guys have wanted to have or build small electronics wise? This is a brainstorming thread so any and all ideas please.

  7. I CAN! put it on youtube give me the link give me about 15 min I'll have a pic for you that can go on the site.

    i would but i was just trying to switch it from a .wmv to a .gif and i fucked it up. im going to have to make another renering whenver i get back to school cause we are out on a snow day today and prolly tomorrow.

    Got your PM btw and thanks i might have you do that ill PM you if or when i get it on youtube.

  8. Its a .GIF You can search Google for .gifs and see what you come up with... and then there are programs that you can use to make them... There is a thread for a couple of people who make them.

    ok so it just has to be a .gif? i have 3d rendering capability at my disposal and parametric modeling (Autodesk Inventor). I made a sub with my custom logo on it and i made a vid of it bumping i want it as my avatar. i will work on it thanks for the info.
