First off, I am an old man trying to learn some new tricks. After stumbling through WinISD and having a fairly successful build, I am moving on to embarrass myself with Hornresp. I have read many of the tapped horn build threads here and it is really amazing what you guys are doing.
So, I am trying to teach myself this program by reverse engineering some of the fine tapped horn cabs you young punks have already built. Are these following assumptions correct?
Using Hornresp, the S1-S5 values are AREA MEASUREMENTS at a particular point of the horn (the internal width of the horn multiplied by the depth of the horn at that point).
The L12-L45 are the actual measurements of the horn fold. They reflect the path the sound follows from the face of the speaker to the output of the cabinet.
If the previous assumption is correct, and I wanted to see the effect of making the cabinet slimmer, I would reduce each of these S1-S5 values proportionally to the new width of the cabinet. I would not alter the L12-L45 values at all.
EXAMPLE: If the cabinet I am studying has an internal width of 24" and I am attempting to model it with an internal width of 18", I would then reduce each S1-S5 values by 25% (18 divided by 24 = 0.75). I would then multiply the original S1-S5 values by 0.75 to see how the cab would model with an interior width of 18". I would not alter the L12-L45 values at all.
If the previous example is correct, then I could also use the same approach if I wanted to model making the cab wider.
EXAMPLE: If the cabinet I am studying has an internal width of 24" and I am attempting to model it with an internal width of 30", I would then increase each S1-S5 values by 25% (30 divided by 24 = 1.25). I would then multiply the original S1-S5 values by 1.25 to see how the cab would model with an interior width of 30". I would not alter the L12-L45 values at all.
So that is my question for today. Hopefully my understanding of this process is correct and my assumptions are true. If not, could one of you boy genius's help an old man out and try to help me understand what I am doing wrong?
