Hello all! This is my first post here! I recently purchased an Re Audio XX 12 v2 and i need help building the perfect box for it. I've ran the parameters through 2 different programs, along with the box recommended by RE, and im rather confused by the results. WinISD says i need a 1.594ft^3 box tuned to 27.4hz Box-Port design II says i need a 3.19ft^3 box tuned to 27.4 hz Re says i need a 4.98ft^3 box tuned to 32.07hz See my confusion?? haha If someone could give me some more insight on this i would greatly appreciate it! Here are the T/S parameters from the RE website to give you all a place to start. I bought the 2ohm dual voice coil Re xx 12
