This is a very rare set of massive Bose 601 Speakers from the '90. Not seen often on the market! These Bose speakers have an 8 ohm impedance that can produce loud, powerful sounds even when used in a system without a strong amplifier, it can withstand up to 200-watts, so they can handle most amps found in home audio systems. The measurements are 76x31x32 cm. They are fully functional. The wooden case is in very good condition. Technically working perfect. Small flaw on one tweeter as seen on the pictures. Fronts are a little dirty. Please check all the pictures closely. VIll.
