$40! the M-15's sold for over $2k when they were new! i had a pair of L-1590's in (real)rosewood and they sounded fantastic, as did a pair of M-12's i heard at a dealer. i don't know about soundstage depth, but A/D/S had the most impressive sstereo imaging i'd ever heard until i upgraded to B&W 801's. you may be able to pop some of the dustcaps outward with a bit of scotch tape. if you're handy and have the time those speakers have an awful lot of potential.
