Hi Florent,

Many thanks for the example file, it enabled me to quickly find and fix the problem.

Hopefully you should now be able to open all your .dat files, without any issues.

Kind regards,

David

Hi kazap,

It is not necessary to regenerate your projects.

Download a copy of the latest release and everything should work fine.

Thanks for the thanks :-).

Kind regards,

David

Hi David, can an "Open Baffle" option be added to the "Driver Arrangement" list in Hornresp?

If I'm thinking this through correctly (which is certainly not always the case!), the only difference between the "Open Baffle" option and the "Compound Horn" option would be automatic calculation of the "Path" value, based on the values for L12, L23, L34 and L45 and the flare rates of the CH. For a simple H-type or N-type OB, Path could be (L12+L23+L34)*2. The situation does get a bit more complex if the OB profile is not an H-type or N-type, but can probably be calculated using the flare rates and a bit of geometry.

BTW, something I've found with a bit of experimentation in Hornresp is that high-inductance drivers could make pretty decent open baffle subwoofers, even if Qts is low, but that's probably a subject for another thread....

Hi Brian,

After giving it some thought, I suspect that it is probably safer to leave things as they are, and have the user make the decisions on path length, etc, depending upon their chosen CH / open baffle / dipole design. As you point out, things start to get complicated when more complex profiles are considered, and the selected path length value becomes what is in effect a "judgement call".

Perhaps you could come up with a series of BOXPLAN-style spreadsheets, for different open baffle designs... :-).

Kind regards,

David

Hi kazap,

Not a problem, I don't like bugs in Hornresp :-).

Kind regards,
