Default Hornresp Update

Hi Everyone,

The Loudspeaker Wizard bug reported by bjorno and mdocod has now been fixed.

The latest release is Product Number 2900-120220.

Kind regards,

David

David...Wow, what a wonderful tool you've created. I've been using Hornresp for about 1.5 years now, and it just keeps getting better. Thank you for all of your hard work.

Hi David,

The last update seems to work great. Thank you so much for adding the isobaric driver feature to your product.

Regards,

Hello David,

In the attached image you can see two phase plots. The only parameter difference between both is the box volume, in one pic its 262l in the other 261l. Should this happen?

regards,

Mathias

Hi 3GGG,

Here is a template: The submitted .txt file to import and tweak using an another driver + adding more CSA:s and sections ,of course, if you want. I fiddled with a horn mouth of 3x2 meters

The PD2450 sims well there and is no1 runner for me currently. Need 20Hz to 110Hz
With a fold that horn looks doable. In hornresp how do i sim a 60cm high horn (similar in design to lazy cats horns and similar but on a smaller scale to those bass horns in Milano), not a circular horn?

I never designed a large sub horn with an aspect ratio larger than 4:1 so for Your 5:1 design: I hand over this question to whom this is an easy question to answer.

Hi 3GGG,

For the purposes of the simulation, assume that the horn is axisymmetric (circular). At bass frequencies the predictions will be accurate enough. A horn mouth 3 metres wide x 60 cm high will have a cross-sectional area of 18000 sq cm.

Kind regards,

David
