Horn Loudspeaker in Car

1st January 2003 - report written and upload

True event around April 2003

Horn Flip Phase

When the horn speakers' wire is flipped 180 degrees there are changes around 480Hz as well as a little at 4.8kHz.

Hhhhhhhhhhhhhmmmmmmmmmmmm didn't know that phase anomalies of filters preserve as high after one decade. Interesting........... wonder what "feel" effects it has on so many other systems out there..........

So, since the mid and horn needs to flip wires, therefore they are reverted back to original then only flip the woofer's wire phase only.

Hmmmm, all 24dB/oct, all linkwitz riley, all same frequency, hmmmm still got problems............... cheh!

Lucky do simulation before installation :) so many ghost :( !!!!!!!!
