Then you need to design active electronic custom crossovers, or use achieve the same use units such as Mini DSP. And, as the title will tell you, i am totally new to all this DIY speaker crossover lark. Lets start by describing an active crossover. Then you need an amp for every frequency band the speaker requires. In some passive crossovers this is adjusted for by reversing the polarity of adjacent loudspeakers. Crossover Points & Order At the crossover point, power to each loudspeaker is reduced -3 dB (1/2) so total sound energy is 1. Also I found this thread, active filter without opamps with the link to Naxo active crossovers by Linn/NIAM. I believe the title says it all. I have a pair of Quad ESL 63 and am trying to design an active cross over. One of the more unique aspects of the ULP is the utilisation of an active crossover rather than the traditional passive crossover found in 95% of commercial designs. Furthermore, my (small) experience with relatively high order active crossovers so far is that it makes for such a small area of overlap at the crossover point that other design constraints can be relaxed a little if need be. Electronic active crossovers can have extra compensating circuitry. I have a CX3400 which I help each other. The A2 differs significantly from the Atom in having a relatively rare sealed cabinet, as opposed to the Atom's rear-ported, bass-reflex design, and an active digital crossover instead of the Atom's passive one. At the crossover point More recent design trends are for power to be decreased to -6 dB (1/4) to each loudspeaker at the crossover point, and the slope rate can be selected. I am planning on a multiple amp setup in my crew cab, most likely fed by a RF 3sixty.3. (This was sent to me by DefTech when i emailed them-they also sent the schematic for the crossover if this helps) Has anyone designed an active crossover that i can use or can you point me in the right direction please.
