claytonc100 Posted May 3, 2020 Report Posted May 3, 2020 Hi, I am currently in the process of designing a complete sound system for a daily driver. I am using the Rockford Fosgate P2 12" Subwoofer and currently in the process of designing the box for it using WinISD. I have the inputed the T/S Parameters and aim in doing a ported box tuned to 34Hz and using the manufacturers recommendation of 1.79cu ft of Net Airspace for the sub. When inputing the data in WinISD, I get these graphs. At F3 I get 32Hz and at 0db I got 36Hz. And there is a peak of 4.2db at 53Hz. Is this correct? Also for Air Velocity I get 16m/s at 22HZ. (400W) Can you please verify if this is correct? I have attached the Function Transfer Magnitude and the Rear Port Air Velocity. This is my first subwoofer box and I wanted to get an opinion from someone who is more experienced. Regards, Clayton
