My email correspondence with Bill goes back years before 2007 :-).

Kind regards,

That's what I did before asking the question. I saw how you where posting about HR in other people's threads. I thought a previous HR thread got deleted or something.

Hi BP1Fanatic,

I started off by just responding to miscellaneous posts I saw that referred to Hornresp. After a while I realised that there was enough interest out there to establish a dedicated thread. As they say, the rest is history :-).

Kind regards,

David

Hi jayam000,

The system you show should be modelled as a compound (CH) horn, as shown in the attachment.

Kind regards,

David

Hello David,

You added the "large coil" check box in the loudspeaker wizard a while back. Thank you for that. It greatly improves the general accuracy of the simulations for modern long xmax bass drivers. However it is difficult to do comparisons between designs since there is no overlay capability as with the main simulations outside of the wizard. Also some of the available simulation curves are not available inside the wizard. Is it possible to add this function to the main input parameters page? I suspect it is too much work? if this is not feasible would it be possible to show, or even export, the modified parameters inside the wizard so they could be copied into the main data input screen and saved to a project? Some way to get this data exported or updated into the main project with out manually doing trial and error adjustments to the input parameters like I've been doing for years would be amazing.

Thanks,

It would be cool to have it in the main program, not just the wizard. There were a few reasons it was chosen to be only in the wizard - maybe we should revisit that? Or maybe it's easier to just display the new value of Bl that Hornresp calculates so it can be entered in the main screen?

In lieu of all that the user could simply use the formula in the paper to get the new number for Bl but I don't even know how to run through that formula on a calculator.

EDIT - the only thing that really changes is Bl, so if we could know the new calculated Bl that would be incredibly useful. Even if it's just displayed in the bottom of the wizard box like how qtc is displayed when simulating a closed box in the wizard.

Also maybe we should revisit the name for the checkbox? The new Rockford super woofer has a massive coil but very little inductance issues. Maybe the checkbox should be the "lossy inductance estimator" feature instead of "large coil"? I'm kind of leaning that way lately after studying the Rockford driver a bit.

Including the word "estimator" in the checkbox feature name would also clear up some of the issues associated with putting in the main program instead of just in the wizard, I would think.

Stuff to think about anyway.
