I am sorry for your loss Steve, however if you want to get the most from the speaker system you really need to listen to it. I would inspect the woofers and midrange drivers to make sure the surrounds are not in need of replacement. In addition make sure the cones are not scraping the walls of the voice coil by gently positioning your hand in a spider pattern and pushing in on the cone. Make a note of the numbers printed on the drivers and compare them with the numbers & years in the link below to determine when the unit was made. If everything checks out good, list it here on AudiogoN, Audio Asylum and AudioMart. I am sure you will find a buyer.
