Pricing for one of a kind speakers

Is there a place to get pricing for a custom one off speaker and DAX?

Leo Spiegel and Jason Bloom (apogee acoustics) built a custom set of Apogee Stereo Subs for me back in 1994 to go with my Divas. I have scoured the net to try and find another example of these and could not. I am getting older and ready to downsize. Thoughts on pricing?
