Okay, I finally downloaded and have started playing with the Adire version of LspCAD to model Sunosub II (version 2.0).
I have a question on the Airspeed in port:
Where should I be focused on when I look at the graph? What is the "danger zone" for the airspeed and at what frequency should I be canvassing when I look at this plot to determine if my design is "okay".
Just to get some more feedback:
I'm thinking about doing the following subwoofer design with the Tempest:
10 ft^3 (285 liters)
Tuned to 16.5Hz (Single 6" wide port, 22.75" long)
LspCAD reports the F3 to be around 19Hz.
(I'm thinking about adding 72 ounces of polyfil to give it a little more "volume", good idea or not?)
If I could make heads or tales out of the airspeed plot, that would help me evaluate the design.
Thumbs up or down for this design?
TIA!
