Time delay problem JBL 4343 (3143 network)
Hello fantastik group !!
(sorry for my poor english)
Recently, I run test calibration with my analyser for check spectrum response on driver.
Big surprise result the time delay integration is little false on cross-over 3143.
The time delay is 0,671 MS more faster for the 2405 for th rest of the drivers.
Well this effect is not change pretty well the sprectrum response but ruin the phase match...
Do you have any information for modification, repair or upgrade cross over for fix this effect ??
(I attache too small pict where the phenomenon is produce.)
thanks
