Tools and material are ready now just need to wait for woofer to arrive and calculate box volume and port area! i used WINisd to get box volume it gave me 85L  or 3.0 cubic ft.

software shows that i need 4x 4" ports total of 35inch lenght in port to get less than 30ms air velocity. peaks about 20.5 M/s

The RE calculator is pretty inaccurate. I have had better luck with Torres Box calculator. Its a free Download.

No its super inaccurate, will almost certainly give you the wrong plans each time. God forbid you try to calculate with more than 1 sub... Either way, you are doing most of the leg work, just do the math your self, and draw it on Google Sketchup.
