Well hear are the dimenions. The box is gonna be 36in wide by 17in deep by 13in tall. It ends up being right around 4.6ft^3. Im using a 15in AQ SDC2.5 tuned around 38hrt. I know the port is 73.6Sqin but i cant figure out how wide on the box to make it and how deep in to go before i make the L shaped port help would be great thanks guys.

how do you know it's 73sqin without knowing the width of the port? That's impossible.

It's widthxheight of the port unless I'm mistaken

well...the turn of the port will be determined by the width of the port...the turn will happen 'the port width' away from the back of the enclosure to keep it all the same size...

port should be about 18" long measured down the center of the port...

Just installed 2 of the SDC2.5's the other day. Impressive subs, hit very how tuned at 38Hz.
