I have the same speakers! All I found was:
Frequency response: 40Hz-20kHz
Crossover frequencies: 1kHz/5kHz
Min/Max Power: 25/130 watts
Max livingroom SPL: 113 dB
Impedance: 8 ohm nominal
Thank you very much. I hadn't found any informaton on these speakers, so now I know at least something about my speakers. Thanks again..
