Finally, my book from Lean Business arrived. I yet have to open it, but it weights something like 10 kilos

Default Hornresp Update 5050-191121

Hi Everyone,

BUG FIX 1

The Lpt label was shown as Lp Lpt in the Loudspeaker Wizard when it should have been shown simply as Lpt. This has now been fixed. Attachments 1 (before) and 2 (after) refer.

BUG FIX 2

The ME1 and ME2 chamber schematic diagrams in the Multiple Entry Horn wizard were correct but the main schematic diagrams were not. These have now been fixed. Attachments 3 (before) and 4 (after) refer.

Kind regards,

David

Bug-man extraordinaire

and thanks for the clarifying work regarding Max SPL tool ..

Quick question about excursion...
Since we input RMS voltage, I assume hornresp uses the peak voltage of a sine wave (+3dB) for determining excursion? (and not some other crest factor)

Still working on frequency dependent limiting for prosound...
...just double checking... thx

Maybe some people can help me out here.

I used to run Hornresp just totally fine a while back under Manjaro Linux Wine with the LC_ALL='C' command.
Since a few weeks I installed Manjaro once again with the newest Wine version and I get an "run-time error '52' " when starting up Hornresp.
Any other people that run into this issue (or at least can replicate) ?

Hi Guys

I'm having a bit of trouble getting my hornresp frequency response graph to match reality closely enough to make design decisions on a project I'm starting. I am trying to simulate a block of 4 punishers sitting on the ground, not next to a wall. Punisher plan is here Punisher Horn MKII

I know from measuring my system with smarrt multiple times that the punishers roll-off at about 40hz. The sim is showing the roll-off at closer to 55hz.

I have tried simming the punishers as both OD and ND but it makes little difference.

You can see all my input parameters and graphs here Help developing Hornresp parameters from plan - Speakerplans.com Forums

I hope linking to my post in another forum is not an issue.

Hi mark100,

The maximum displacement of the driver diaphragm from its mean position is given by:

Dd = Sqrt(2) * Vd / (2 * Pi * f)

Where Vd is the rms velocity of the driver diaphragm at frequency f, and for rms input voltage Eg.

Kind regards,

David

Hi b_force,

Just to clarify - is the version of Hornresp that no longer works, the same as the one you were successfully using before you updated Wine?

Kind regards,

David
