Kit without housing  price per speaker

Gatria is a two-way floorstanding loudspeaker. Gatria is a bass reflex loudspeaker with chassis from Scan Speak and Wavecor. The loudspeaker contains the following loudspeaker chassis: - a Scan-Speak R2904-700005 tweeter - two Wavecor WF182CU13 woofers. The crossover consists of: - a 3rd order high pass (18 dB / octave) with blocking circuits connected in series for the tweeter. - a 3rd order low pass (18 dB / octave) for the woofer. In addition, an optional tweeter blocking circuit can be used, which lowers the level that increases from 13 KHz. We recommend this blocking circuit for very poorly dampened rooms. The frequency response of the loudspeaker is perfectly linear. The decay spectrum is practically flawless. The nonlinear distortions at low volumes (85 dB, 1 m) are below 0.6% above 400 Hz and remain below 1.5% in the audible range even at higher levels (95 dB, 1 m).
