Beautiful set of Pioneer HPM 150's for sale. One of the milestones in dynamic vintage loudspeakers. Possibly the coolest vintage speakers ever made, the Pioneer HPM 150, the big brother to the Pioneer HPM 100's considered one of the best speakers ever, specifically built to be better than the JBL L100! The HPM-150 was designed by Bart Locanthi, formerly of JBL, with the same mid and tweeter as the 100 but with a larger 15" bass driver and the 270 degree super tweeter, and larger cabinet all of which adds to and surpasses the great performance of the HPM 100's. In the late 70's when these were produced Pioneer was considered the number one Audio Hi-Fi company in the world. If you are a fan of the big Pioneer Receiver's & Amps these will complete your system. These are in Very Good condition and it is rare to find these with the original 15 inch Bass drivers intact!
