I am building a box for two eD e12K's (the good ol flat cone models and I have a few quesitions. Here is a pic of the box as it is now for reference:
1.) How much breathing room is the minimum between the magnet and box floor? The subs will nearly touching on one side, and have about 1.5-2" of clearance on the other end. Is that enough space?
2.) I determined the rough volume of each side of the box. My calculations do not take into consideration the volume of the driver, and I am considering the final shape of the fiberglass top to be a wash since one side dips in and the other sticks out. Seperately, it will be 1.09 ft^2 for each sub. I will have 400wrms going to each of them. Any of you box designers have any suggestions for me or does this size seem about right? I have the option to cut a couple holes into the middle chamber to gain another 1/4 of a cube (divided between both subs), but I think I would need to decrease the volume if anything.
