[QUOTE="Κακαλιός Στέργιος, post: 126174, member: 11"] και... "My tweak is not really a Zobel network although it may look like one. The point is to provide a dissipative path for out-of-band energy stored in the bass panel, not to change the loading on the network. The bass panel low-pass filter in the MG-20 crossover is two inductors and a capacitor. The last element before the panel is an inductor. This presents a high impedance to the bass panel for frequencies above the low-pass cutoff. Resonances in the bass panel are underdamped by the amplifier with this high impedance in the way. Notice that active crossovers used in bi-amp setups circumvent this problem. The amp is fully able to damp the bass panel at all frequencies, not just the active range. I believe part of the benefit reported for active crossovers is this full-range damping. [U] Adding Zobel networks to Maggie drivers will not change their phase relationships, but might affect second-order phenomena such as out-of-band resonance[/U]s." καλό αυτό ε? [/QUOTE]
