Pioneer HPM-60 is a vintage 4-way, 4-driver bass-reflex loudspeaker system.TESTED! Cabinets were sanded with an oscillating sander using 600 grit sandpaper, then coated with MINIWAX SPECIAL WALNUT STAIN.  Speakers will be shipped via UPS INSURED WITH TRACKING. In the next couple of weeks I will be posting approximately 50 sets of classic speakers I accumulated over the years. Watch my listings!
