Topic: Optimizing High-Efficiency
The project was to investigate high-efficiency
horn loudspeakers with a classic home speaker
as a representative example, the Altec Model 19. We
had three objectives: first to characterize the horn
and driver, both the original Altec and a JBL equivalent.
The second objective was to optimize the configuration,
including bass driver and enclosure. Lastly we intended
to fabricate a new horn and enclosure in hardwood and
hardwood veneer. The project was not completed; the
presentation is more of an overview, with some conclusions.
There will be refreshments at 5:30.
