The Crossover is as simple as it gets. The highpass feeding the David "satellite" is a simple 1st order Unit. Note that the output to the Satellite is inverted in Phase. However, depending upon the room and listening conditions it may be neccesary to connect the David "satellite" in phase in order to avoid room resonances. Feel free to experiment.

The Lowpass feeding the Woofers uses an Impedance Compensation. If the Dynaudio 21W-54 Woofers are employed, this Compensation is un-neccesary and should be omitted. It might be desirable to connect a high power resistor of 15 Ohm Value (> 50W) across the Woofers to slightly attenuate the woofers as well as reducing the Impedance swing at low frequencies.

Again, building methodes and part quality are to the higest standards. The Wire to the woofers was left as conventional stranded wire, the wires to the crossover as well as those to the connectors feeding the David Satellite Speakers are made from the same DIY-Litzwire that was used in the Satellite. The short Interconnection between Woofer and Satellite also uses this wire.
