This is my first design so let me know what you think. This box is going to go in the bed of my s-10 with a blowthrough. The subs are T3 TSS 10's and for power I will have a mm4000.1. The sealed chamber is 1.5cubes and the ported chamber is 6cubes. The design has a port of 12.5 by 8 which is 100sq in of port. Being this is my first bp I am unsure of what to tune it to or if this is enough port area. Any thoughts or tips would be very appreciated. I would like to make the port interchangeable so that I could put up a good number on the meter and then for daily and hit the lows. So what do you think?

how many 10s? go with more port area ~ 25 sq per cubic ft. so id say 140-175 tune 40-60

thats just general numbers from what im reading of other designs try pming some of the well known designers 80INCHES mobeious iamamp3pimp galacticmonkey

The build is for 2 10's. I thought I had the pic working but I cant figure out how to convert it over from sketchup.

u can only use so much port before it acts as a sealed enclosure instead of a bandpass be careful

do u think that 100sq in is too much and what about some tuning?

to convert it from sketchup hit the print screen button then paste it in paint or a progam like it

i would try 1 cube sealed each firing into 3 each around 50hz

I think I got the pic fixed

that indeed looks like a bandpass box, but theres no dimensions... :)

File/export/export 2d image then change the file type to Jpeg.

Thanks Marco for putting my name in that list.

The inside deminsions are 7.25x34.5x12.5 for the sealed chamber which brings it to 1.8 cubes before sub displacement and the inside deminsions of the ported chamber are 17x53.5x12.5 which brings it to 6.5cubes before the port. In this design the port is 8x12.5 for 100sq in of port tuned to 50hz. I'm not sure if that is the right amount of port or not as well as correct tuning?
