Hello people! First of all: I got so far away with the noises and above all the noise. Stömüsche with the help of the NF filter and the noise simply by changing the final stage in the trunk. The stands now exactly on the other side of the trunk. Since then the noise has completely disappeared. Can not explain to me. But mainly it does. Thanks to everyone for the fast and competent help! To the actual question: I operate my front system active. Now I can set the following transition frequencies with tens of different filter levels: 6kH 5kH 4kH 3,15kH 2.5kH each with -6dB -12dB -18dB -24dB How should I separate the woofer and tweeter from each other?? Do not want to fry my tweeter. Now I have chosen the following constellation: TM-tones: separates the tweeter with a filter of -6dB the tweeter with a filter of -24db Is that okay?
