can someone tell me wtf 14.28 sq. inches per cubic foot means!???? My box will be in three dimensions, not two, so i have no idea what 14.28 inches per cubic foot means. What i need is the number of inches ^3 per cubic foot. My box will be roughly 17.5" wide x 24-26 " tall x however many inches deep it takes. 6.3 cubic feet, 90 sq. inch port, 32 hz tuning is the goal. PLEASE HELP ME I NEED TO START CONSTRUCTION SOON also, does anyone know an fi email that they actually answer fast that can give me help??? i can only get through using sales@ficaraudio.com, and that doesn't sound like tech support.

Just got my 18" Q w/BP in the mail yesterday. (thx scott). Next week is spring break and I need a box design for the back of a 97 blazer. I have about 8 cubes to work with. Accordman from steavemeadeforums told me to go 6.3 ft^3 and 90 in^3 of port, which results in a 32-33 hz tuning. I have never worked with 18's before, and I've heard certain boxes for 18" Q's can really restrict their output. I only have about 1000 watts RMS from a bxi1206d to work with for now, but plan on upgrading to 1400watts rms. My goal is to make a well balanced box. Not pure SPL or superlow tuning for SQ. I just want to get the most, good sounding output from the sub. And i'm a broke ass college student so I can't afford to play around with different boxes, i wanna hit it on the money first time. here is a quick sketch i did. Top will be double baffle, and I will add some form of bracing. nothing is to scale, just a quick sketch to show you what design I plan on using.
