Hi,
this Winter i would like to build a Labhorn. I've got the Eminence Speakers already.
I have found some hornresp data via Google Images (i dont know exactly where i got them from).
The simulation showed a 3,5dB dip at 45hz. So i started experimenting and end up in decr. Throatchamber (Frontchamber?) volume by 10liters and increasing rearchamber volume by 10 Liters. You can probably archieve this by moving the Driver a bit towards hornthroat... Horn flare would change as well.
After I did this, i found out, that Brian Litz has already done this (Labhorn v3), and that this type of Labhorn has already been built.
Sadly every link to building plans that i have found is down.
Could someone help me getting theese plans please?
I guess theese plans:
https://www.prosoundweb.com/channels/live-sound/lsp_documentation_page_drawings_photos_specs_and_more/, don't include Brian Litz improvements.
The measurement (
https://www.prosoundweb.com/lsp/response1.gif) shows the same Dip at 45hz.
2nd Question:
Is there Hornresponse input Data for the plans shown on the Documentation page?
Is there Hornresponse input Data for the plans of Brian Litz?
If not, of course i will create the Data by myself and post it here.
Of course i will post Measurements of the finished Horn afterwards.
Btw: I archieved some nice Result's in (at least in frequency response) using Passive Radiators. Probably someone with more Knowledge could take a look at theese. (Hornresp records are attached)
Best regards
