What would you do with these?

Found a pair of Ohm Acoustics Model I speakers. The problem is the woofers have been replaced with pyramid drivers. I know that Ohm still supports their speakers but I believe you have to send in the old one for rebuild. I doubt I will be able to find a pair of 40 year old drivers. The Ohm website lists a price of $195 for the updated driver, I assume that is each. There are other drivers that should be replaced as well. One mid tweeter has been replaced with something else. It would be quite expensive to fully update the speakers but the website claims completely refurbished speaker pairs sell for approximately $2500.

The money it cost to upgrade could get buy some nice, newer, used speakers here or craigslist etc. So, keep and hope to upgrade one day or sell as parts?
