Pricing Dunlavy Audio Labs SC-VI speakers


I have two pairs of speakers for sale:
Dunlavy Audio Labs SC-VI
and
Martin Logan Monolith III. Endeavoring to ascertain a fair market price.
Recommendations?
Thanks

The VI weigh over 500 pounds each.  They really were great speakers.  The difficulty with them now is the drivers were custom and I believe there are no perfect replacements.

What was the selling price on the Dunlavy speakers and was it a local sale?
