Looking to price my Genesis G350 Loudspeakers with 1500w Servo AMP

Hello Forum!

   I have a pair of Genesis 350 Loudspeakers with the 1500w servo amp (w/ remote) and upgraded extended length cables. The specs are below. I am looking to price these to sell as they have not been used in a while and they take up space. I bought them for $22,000 in 1999(ish). Does anyone have a good idea about a price to set for these in near perfect condition with all the manuals and advertising material? I looked it up on Audio Bluebook and it listed a sale for $26,000 but I am not sure if that is accurate. Please let me know your opinion if possible. I am looking to make as much as I can without getting ripped off. These were designed by Arnie Nudell himself (founder of genesis and infinity)
