1 driver tapped horn / hornresp

[vrfood]

Okay, fixed it..now everything looks perfect. Just a question of how to fold it and incorporate the stuffing and filters as painlessly as possible. I noticed that Hornresp does not save the changes you make under filling and filters to be view-able at the general "Acoustic power" window. Is there a way to make it show whatever changes I've made and display them outside of the "Loudspeaker wizard" window?

Guys, I started calculating the TH's dimensions in order to fold it, but I can't get into the Horn Segment Wizard in Hornresp, as it is greyed out..

(which I guess is where this menu is in the new versions of Hornresp)

So, how do I get access to this menu, so I can export the file with all the numbers?
Or, is there a spreadsheet available where one can put in the segment data from Hornresp and get out the possible sizes; what's your advice on the best way to do this, guys?

Cheers

I also have a question about the segments in reality; where does each one end and respectively, where does the other start (where does S1 end and S2 start). My thinking is, that having a certain volume as well as a certain length, is what constitutes a segment as such. Is that correct? Most diagrams, such as this one, seem pretty confusing:

It looks like segments start and end depending on where the driver is.

Hi..FYI:

From the Schematic window go to File - Export - Horn Data.

S2 is defined as the driver tap point. So the center of the driver is at S2. In that diagram the same thing goes for S3.

I guess, looking at bjorno's sim, having a L12 of 155cm is what confuses me the most.. where am I supposed to put the driver, then? I think that's why the guides say to use small L12 and L34 that are also equal..

 

[just a guy]

There are all kinds of simple ways to fold a horn. If you want a simple single fold you need the first and last segment lengths to be almost equal.

 

[vrfood]

So, I played around with Hornresp some more, keeping in mind what I'd like the TH's parameters to be. I wanted a L12 that's somewhat small as well as L34 that's a little bit larger in value, but not too much. Also with the filters I wanna use and some stuffing.. Here are some sims, please, take a look:

The response looks good to me, as well as the XMAX at 15W/3.6R

Apparently it does since some were worked out in the other thread.

Regardless, in the future, please start your own build thread rather than posting on others.
