| Great to see another build in the formative stages...
994Hz is right for a normal N23 panel of 5.35 inches, but the inverse will be deeper....
If you are going to use inverse panels as well as normal panels, your maximum build depth will be set by the inverse panel.
An N23 inverse with a build depth of your stated limit of 5.35 inches has a design frequency of 1265Hz. The normal panel needs the same frequency and gets a build depth of 4.17 inches
Now have a look at advanced mode with both "Auto-optimise build depth" and "Panel will be used in a sequence that includes its inverse" turned on.
You get a deeper N23+2 normal panel and a shallower N23-2 inverse. The maximum build depth of this pairing is more economical than the unoptimised inverse.
The inverse has a build depth of 5.35 inches as before, but the design frequency is improved to 1155Hz. The normal panel is the same frequency and has a build depth of 5.11 inches.
Regarding Xenon's build - find his thread and send him a PM.
The other questions I'll leave to the acoustic experts.... |
