B&W Matrix 2, Series 2...are they worth selling?

I have a pair of 1989 vintage B&W Matrix 2 Series 2 speakers (walnut) that have been replaced by ProAc Response D2s.  The B&Ws were with me since 1989 and are in good condition but I don't know if there's a resale market for them.  

Be interested in the community's thoughts about selling these v. just donating them somewhere....
