    Sketchup PICS INSIDE!!! will this box design work (port in question)






    So...I know i'll make it probably 6+ inches longer to make the 1.125 cubic foot requirement, however, all I'm curious about now is the port design...will it work? I'll be puttin a 10w3v2 D4 sub in it, and according to JL's website blah blah well the port is the right dimensions, just not sure if its okay for it to do a 180 degree bend like this...

    depending on enclosure dimensions it seems as if pvc or maybe prescision ports would better suit this particular design for ease of construction as well as helping to meet your space requirements

    The interior end of the port needs to open far enough away from the wall that the wall itself does not create its own porting effect. From that sketch, it looks liek a possible issue.

    Yeah. I got that worked on I think. I started building this yesterday, mostly done just basically gotta put in the port. What I did was extend this 5 inches on the side of the port, drop the top from 17 to 16 inches (makes it less visible behind my seat) and had the port come into the interior 14 inches, then curve back around 10 inches. I'm pretty sure it'll work well like that. (I also put the port lower in the box so it would have more space for the air, and the box walls would act less like an extension of the port.)

    Reducing the port height will not reduce port end correction. It is the nature of slot ports, and can not be corrected by adjusting dimensions.

    So you have 4" from the port opening to the enclosure wall...

    What are your port dimensions?

    Well it is being built according to jl's website (volume wise, 1.125 ft^3) to tune it to ~34 hz. The port is 10.5" x 1.25" x 24.8".

    Well building is almost complete so im just hoping for the best. If it doesnt work well then I'll just use my existing sealed box or i'll redo calculations according to what, if anything, goes wrong and try it again

    I'm not reducing the port heigth, just making the port sit lower in the box, since the box has a slanted front, if the port is set higher in the box, there will be less room in between the opening of the port, and the front panel....if its lower there will be a few inches still for an opending and that should work out better.
