The listening trials show that the document that was published for the JBL M2 speaker digital crossovers are different than the original versions.
I asked in the JBL forum about the original response graphs to see if anyone still has them with the scales intact. Would need those to see what the difference is, or measure a pair of original crossovers. The tweeter response it to hot even with the gains shown.
Until then, the system is on hold.
