WinISD help

[KilluminatiDre 10+ year member]

I'm trying to learn and understand the winisd pro program but I've ran into a problem. If I design a box to manufacture specs and tuning the SPL graph always shows greater SPL above the tuning frequency. Shouldn't the SPL be greatest at the tuning freq? I'm sure that I'm doing something wrong but I don't know what.

give me your sub t/s parameters so I can see what you're talking about.

what's the size of the box you're putting it in and tuning frequency.

I'm guessing the peak is due to a weak motor.

I was playing around with 3 and 4 cubes ranging from 30-35hz

yeah, a weak motor will give you that kind of response shape. But that doesn't mean it's bad....
