Ok I have WinISD and have mu numbers and graphs, but how do you use the information to design my box? What numbers am I looking for.
Gain:
Phase Plot:
SPL:
Group Delay:
I see that on the subwoofer window you can change the volume and tuning frequency, vents, plot, etc.
I know what the volume and tuning is for...internal volume and desired tuned frequency but doesn't the frequency change depending on the box dimensions? EX. (not real numbers) If a 2 cf box 24x12x12 with a 2" port, length 18inches is tuned to 34hz, would the tuning be the same as a 2cf box 28x11.25x11 with a 2" port, length 18inches?
Or should I just be using WINISD for the graphs? If so what am I trying to achieve, a certain point where free meets db's?
Sorry for all the questions. I think its very interesting how people can design the boxes tuned to certain frequencies and would like to learn to do it myself.
