i was looking up designs for front facing subwoofers/front facing ports.there was 2 designs that got me thinking......i see more people use the L-bend port on a suwoofer box .....like this and less people use a design like this im not a big box builder.....so can somebody tell me why most people use the L-bend instead of the dual chamber middle port design........is it because u get both subs working together in same chamber? and how would it change the air flow from side port to middle?

I made up a few pages for port tuning, that account for port displacement, as I haven't seen anything online that offered it. Slot Port: http://portsgalore.stefanhinote.com/?do=portlength Aero Ports: http://portsgalore.stefanhinote.com/?do=portaerolength It uses the port length equation from the loudspeaker cookbook. Input: volume, port dimensions, tuning. It figures out the port length, and port volume (port length * port area). Subtracts port volume from original volume = net volume. With the found port length and net volume, it figures out the real tuning. From there it has something to start with, and starts adjusting the original tuning frequency until the net tuning…

Hi, so I'm in the process of fixing up my 300zx twin turbo and am figuring out designs for sub boxes and want some advice on configurations etc. I have two re se10s I was thinking of using or Incriminator i10s on around 150rms a peice (keeping power low to avoid having to upgrade electrical and going more for sound quality over getting loud.) My issue is I want to do a box in either side of my hatch but there are some lines on the one side which makes it have a much smaller available space. My question is should I make both boxes fill up the space and have different size boxes or make them both match? I will probably stay sealed to avoid having to figure out airspace an…

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?

Do I fire my sub towards my trunk lid or into my vehicle? I have asked several people and now I'm going to ask the proz.....which way would yeild the better sound? I head that on paper it should be the same? Could you guys tell me why i should do either or? PLEASE - THANKS

i got a bigger amp for my 10's and now my back wall of my truck flex's way to much ...it has a knocking sound i can make it stop buy pushing as hard as i can on the consol ...what would be the best way to stiffen the wall...the box is bolted to it but only at the bottom ..i could put some more bolts into the top but im not sure it would end it ...another idea i have is to weld some tubing to the back of the wall inbetween the cab and bed ..well here is the only pic i have to show where the consol meats the wall

im currently evaluating a couple of designs for my setup and this is one of them i would love to get as much feedback on this as possible. it will be in a 95 single cab dodge ram.

For the past couple of months I have been playing around with imaging. been reading everything I could get my hands on, even picked several brains along the way. I started my project with simple goals in mind. But after listening to others systems, as well as my own. My goals keep getting raised I built the kicks allready. Temporarily using a pair of $1 crunch midbasses ( I love yard sales ) and a pair of large format PE silk domes. Simple inline crossovers. powered by an rf 200a4. To my amazement, and a few others. The sound was rather nice with no processing what so ever. So my goal has now changed once again. I was originally building towards a single seat soundstage…

Ok so speaking purely visually, i understand a basic motor and the LMT but XBL^2 i've never seen a good pic of, what exactly is it and how does it differ? what pics i have seen, i can't tell the difference from a normal motor. Now, someone explain in some more depth for me, or point me to a good link, the way the magnetic force helps hurts the voice coil movement. I'm not understanding why a lateral force is necessarily a good thing. Next, why is the cone concave instead of convex? Has anyone ever experimented with flipping the cone over? What affects would this have on the frequency? Obviously i'm procrastinating studying and my mind needs anything else to think abou…

Hey everyone. I am not sure what the policies are with box designs are here so i thought i would ask. If I asked for a design on the forum and someone does give me one do i pay them or what?? this is just a picture of the box. Like the dimensions of the pieces of wood. I could make the box but i have no clue on how to design a port or tune a box. If this was not clear or difficult to understand than let me know or just delete it , hha Thanks, Matt Cusack

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.

ok well I have been toying with the idea of 2 15's in a wall in the bug (13cf gross) but will that much air movein in their cause cancelation or something that would hurt my score more than help it. I also only have usaci comps up where I'm at so I am allowed to open my doors and such just woundering. Thank mc
