[QUOTE="I Like Waffle, post: 5794536, member: 600248"] Im working on building a box for 2 10"s i just picked up. Box will be subs back port back most likely. Box design i have so far is 20" deep, 30" wide, and 12.5" tall, thatll get me the displacement i need for them after port and driver displacement. Going in a trunk car like an accord or something similar. Here are the driver specs T/S Specs: FS: 29hz QMS: 4.68 QES: .33 QTS: .31 VAS (ltrs): 53.96 xmax (1 way): 10mm Manufacturer reccomends 1.5 cube ported to 50 hz with 2 3" aero ports 13.5 inches long. When i use win ISD to calculate it its telling me i need 2 3 inch ports that are 1.5 inches long to tune to 45. Am i doing something wrong here? I havent got much experience with ported boxed but im gonna tune these 10s a little lower than reccomended to see if i can get some more low end out of them. Box pros chime in? [/QUOTE]
