My parents bought these speakers in the late 80s and have been the only owners. We want them to go to a good home, one in which they will much appreciated. I have been told we should get from $700 to $1000. Is this accurate? If so, can I sell through this site? I believe they are Chorus speakers in walnut? On back it says CHR WO, serial # 8872013. We are located in Farmington, Michigan. Any help and/or advice you guys can give me is appreciated!
