These speakers have re-built crossover boards. The old electrolytic capacitors have been replaced with new capacitors from beoparts.com. This restores the speakers to their original sound. The Beovox S-75 series are 4-8 ohm 100 watt speakers. These come with floor stands and cables. I have cables of various lengths of your choice. Technical information on these speakers may be found at Beoworld.com.
