Hornresp Update 5740-250413

Hi Everyone,

CHANGE

Previously a mass loaded transmission line loudspeaker design template generated using the Input Wizard had four segments, with the third segment being 0.01 cm long to act as the interface between the end of the transmission line and the port tube mass loading (see Attachment 1). The MLTL design template now has three stepped segments (see Attachment 2).

BUG FIX

With a bass reflex design if the green fundamental frequency marker was added to the loudspeaker wizard charts (see Attachment 3) and the Schematic or System Model option then selected (see Attachment 4), when the Lpt label was double-clicked to include or remove the end correction the Helmholtz resonance frequency value was not being updated (see Attachment 5). This has now been fixed (see Attachment 6).

Kind regards,

David

Hello David,

The Sherlock in me saw a color difference related to RP between attachment 4 and 5 (from yellow to blue), this is to provide a visual feedback to the user that RP has changed due to end correction flag. Are there other blocks from System Model that change their colors to indicate flag state? Interesting feature, you are always bringing improvements.

D may change color to indicate semi-inductance flag on.
Horn segment H1, H2, H3, H4, may change color to indicate continuous or stepped.

I'm not remembering all the flags activated by double clicks.

Best regards,

Marcelo

The Sherlock in me

My dear Holmes,

RP and PT change to blue when Lpt has no end correction because the port tube then effectively operates similar to a segment (which is normally also blue).

Segments change from blue to grey when filling material is added, as does the rear chamber (from green) when acoustical lining material is specified.

Lossy Le, Semi-inductance and FDD models are already indicated by check boxes.

Stepped segments are already indicated by the area slider label.

Kind regards,

Dr. Watson 🙂

My poor head. When will I ever catch up. 25 years using this program and I still don't know all the parts 😊

Hi Everyone,

CHANGE

The Input Wizard now has a U-Frame open baffle loudspeaker option, and the closed box, passive radiator, bass reflex and transmission line options now have associated explanatory notes.

Kind regards,

David

That is a neat addition to the wizard 👍

Hi Everyone,

BUG FIX

Steps to generate the error:

1. Calculate bass reflex loudspeaker combined acoustical power response
2. Select menu Tools > Output > Direct Radiator
3. Select menu Window > Phase Response
4. Capture current results
5. Select menu Window > Acoustical Power
6. Select menu Tools > Output > Port
7. Select menu Window > Phase Response
8. Select menu Tools > Compare Captured

Form title should read Hornresp - Phase Response not Hornresp - Acoustical Power:

The bug has now been fixed:

Kind regards,

David

Unfortunately the bug is not fully fixed. Another update coming in the next few days.
