Avalon Acoustics Ascent MKii value?


Hello

I found someone who is selling these Avalon Acoustics Acent MKii speakers.  Giant, grey/silver.  And I simply have no idea where to start in terms of making hi an offer that is fair to him and leaves room for me to easily sell them for a profit.  Any tips or any resources where I can find out more information about valuing these would be greatly appreciated!  Thanks!

Thank ya'll for the info.  Any idea what I would be able to sell them for if I wanted to price them low enough to move quickly?
For both,

They are a good speaker but not avalons best and even though the new cost was about 25k They will be a tough sale used even if they are in very good shape.

The woodwork needs to be very good and all drivers working properly,you probably want to test them out.They also are a very heavy speaker weighing at least 130 lbs each.

Used speakers are really tough to sale.

Thanks for all of your help Kenny.  One more thing, you say wood work,  these are like all silver colored.  I am guessing they are wood but is that normal for these to be the color silver or does it tell you anything about the year?
