A friend of mine wants me to try and sell these speakers for him. They are in near mint condition. What would be a fair asking price for these speakers. I see the C-5 is currently selling on ebay in the $150-200 range but the KLF-20 has not been on auction lately. If someone can offer a ballpark number I'd appreciate it. If there is any interest please leave a post here. These speakers are located in New Haven, Conn.
