Old set of Yamaha 690 II speakers. I don't know much about speakers but I hooked them up to a tuner and they seemed to work fine. However, they have had a hard life and when I pulled the damaged grills off I found that someone had used blue tape around the edges of the woofers where the original material had been. After carefully removing the blue tape the woofers make an annoying vibration. Maybe you will want to put the tape back on or get them professionally repaired. I also noticed that no sound was coming out of one of the mid range speakers. The furniture has had a hard life, with the worst place shown in the last picture. Look at the pictures closely and remember that these are sold as-is. The grills are in bad shape but could make good patterns. Someone had used an air stapler to attach the grills with one staple top and bottom because the clasps weren't holding or had broken.

I have also listed 3 other old pieces of audio equipment.
