Set of beautiful high end speakers from the German quality brand Quadral. Besides a tweeter on the front there is also a tweeter on the back so that the speakers sound really spacious, it seems like you listen to much larger speakers! The speakers sound fantastic and are easy to control with many amplifiers. The speakers have some signs of wear: on a speaker cabinet there are some scratches on top of the speakers, and a small dent on the other (see the photos). I will add this for the record. The sound quality is no less because of it, technically they are 100%. Optical 90%. Speakers will be sold without the faceplates. • Type: 3-way Bass-Reflex Stereo compact surround speakers • Built: approx. 2000 - 2004 • Nominal/music power (W): 100 Watt continue / 150 Watt max • Frequency response (Hz): 45 - 24.000 Hz • Crossover frequency (Hz): 2.800 / 3.500 Hz • Efficiency (dB/1W/1m): 86 dB/1W/1m • Impedance (Ohm): 4 - 8 Ohm • Tweeter: 25 mm Ø dome Titan-Kalotte, 1x 13 mm Ø Titan-Kalotte • Woofer: 135 mm Ø ALTIMA® • Passive 100 watts • Cabinet size (hxwxd) 330 x 165 x 225 mm. • Weight: 5.95 kg.
