B & W DM 7 MK2

Price seems very reasonable.  It's a good purchase if you like the way they sound.  

excellent speakers in their day

rich sound with a smooth top end

built like tanks too

listen to them before buying, at various volumes -- make sure drivers and cross-overs are ok, nothing cracked rotten or otherwise needing refurb or replacement

old european high end speakers can be like old german cars if you are not careful -- buy 'em cheap, then spend 2-5x more getting them fixed so they work properly

"...I realize the speakers are over 20 years but appear to be in good condition. I like to listen to 80's music..."

You need 40 year old speakers to listen to 80s music. 20 year old speakers will miss the entire New Wave sound.....
