Check again in hornresp, the enclosure is drawn incorrectly, in reality that space is extended, but the program does not know about the driver shape

 

[maxolini]

So the CSA's of the drawing don't match the HR screen?

[maxolini]

Uh?? What you mean?
Will you elaborate

 

[cvl05]

I explained in those pictures how sound waves travel and no need others deflectors, push themselves out and create their own reflections and volume is essential here.

In third picture how the two parts of the driver enter in phase together, here we have an increased power.

Hornresp does't know how driver are installed and we have addition volume.

10-4, so the drawing is not right you said, you mean V1 vs V2?

 

[cvl05]

It's too tight here seems for 75mm, last drawing are 86mm perhaps more depend of driver

 

[maxolini]

well, i guess depending on what driver you will use it is the adjust you need to do

hope XOC1 will chime in

Have a look at post #2,963 which shows the CSA for 18SW115 that XOC calculated.
