Celestion HiFi-PA 2x8/2 floorstanding speakers Kit with high-end crossover

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

HiFi-PA 2x8/2 is a two-way floor-standing loudspeaker. HiFi-PA 2x8/2 is a bass reflex loudspeaker with chassis from Celestion and Monacor. The loudspeaker contains the following loudspeaker chassis: - a Monacor MRH-180 tweeter with Celestion CDX1-1747 drive - two Monacor SP-8/150 PRO woofers The loudspeaker was developed by Bernd Timmermanns. The crossover consists of: - a 2nd order high pass (12 dB / octave) for the tweeter. - a 3rd order low pass (18 dB / octave) for the woofer. The frequency response of the loudspeaker is balanced. The decay spectrum is practically flawless. The non-linear distortions at medium volumes (90 dB, 1m) are below 0.6% above 100 Hz.

The high-end kit is equipped with baked varnish 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 Monacor MRH-180 with Celestion CDX1-1747 - where quality is particularly important - are high-quality Mundorf EVO oil MKP capacitors with 450 V.
