Hi, David!

I make a point of answering every e-mail I receive from Hornresp users - even when I know my reply may not be what they were hoping to hear :-).
Rambler works very bad last time But no matter.

Of course I speak about transmission lines and hybrid loudspeakers. Right designed horns don't need to be filled - It's true!

Hornresp very well and exact calculates the TL's! For full happiness missing only two things - ability to simulate offset port and losses by filling in channel of transmission (labirynth).

Thank you for replies! Alexander.

Hi Alexander,

I assume you are aware of the following new simulation program? It seems to allow filling / stuffing to be specified.

David, one more question.

Will it be possible in future to simulate compaund horn and BReflex with LeCleach flare front horn?

Hi Charcoal,

The way that Hornresp has evolved, a massive amount of work would now be required to modify the program to allow other than a parabolic, conical or exponential flare to be specified for the second or front horn in a compound horn design. Unfortunately I am not in a position to undertake such a large re-build of the software.

Kind regards,

David

Default Hornresp Update 3000-121024

Hi Everyone,

Due to an oversight on my part, under some conditions the phase response chart when printed could be different to the chart displayed on the screen.

This problem has now been fixed.

Kind regards,

David

Hi David,

I just ran into a small problem with the response display in the Wizard v. the SPL screen:

Are you referring to the difference in the resonance spike?

Would it be possible that if you matched the horizontal scale, you might see the same amount of details?

Or am I missing your point?

Hi Mark,

I'm talking about the big spikes around 50-65Hz in the Wizard v. the small blips around 60Hz in the SPL screen. In this particular case it doesn't matter much, but, I thought David would like to see this.

I think both displays should be the same (how do I change the horizontal scale?).

Regards,

The graph on the right has a 2 khz bandwidth.

The graph on the left has a 20khz bandwidth.

Might explain the differences.

Hi Mark,

Yes, I noticed that, and thought that's what you are referring to, but how can I get them to be equal?

Regards,
