What is killing my 900Hz to 2kHz repsonse?

[QUOTE="Atjan, post: 545226, member: 2323"] @Rick Here's a quote from the Zaph Audio website: " It is functionally 4th order Linkwitz-Riley with a slightly shallower slope on the woofer to help with the acoustic center offset between the woofer and the tweeter. We have third order electrical on the tweeter and 2nd order electrical on the woofer to reach our target acoustic slopes.

A traditional L-pad would not have been enough to damp the tweeter's impedance peak and a LCR circuit will be needed with almost all 6600 applications to avoid ringing.
