Audaphon Big King Floorstanding Speakers Kit with high-end crossover

Kit with high-end crossover without housing, price per speaker

Big King is a three-way floorstanding loudspeaker. Big King is the big brother of Little King, with significantly more bass power. Big King is a closed loudspeaker with chassis from Audaphon, SEAS and Wavecor. The loudspeaker contains the following chassis: - an air motion transformer (ribbon tweeter) Audaphon AMT 1i - a midrange speaker SEAS Excel W18EX001 - four woofers Wavecor SW280WA01 The crossover consists of: - a 2nd order high pass (12 dB / octave) for the tweeter. - a band pass consisting of a 2nd order high pass (12 dB / octave) and a 2nd order low pass (12 dB / octave) for the mid-bass loudspeaker. - a 2nd order low pass (12 dB / octave) for the bass loudspeaker. The frequency response of the loudspeaker is perfectly linear. The decay spectrum is practically error-free. The non-linear distortions at low volumes (85 dB, 1 m) are below 0.4% above 300 Hz and remain below 0.6% in the audible range even at higher levels (95 dB, 1 m).

The high-end kit is equipped with baked enamel coils in the important places to reduce the microphonic effect (the current through the coil generates a magnetic field, which in turn sets the winding in motion. This movement induces voltages in the coil, which are added to the useful signal. The tighter the winding of the coil, the less the useful signal is distorted.) The capacitors for the Audaphon AMT 1i - where quality is particularly important - are high-quality Clarity Cap CSA MKP capacitors with 630 V. In addition, a particularly low-impedance core coil with 1.8 mm wire is used for the woofers.
