MW Audio MT-4120: Pioneer Copy Tweeter for HPM series
Pioneer has discontinued the popular HPM series tweeter many years ago and we now have a great replacement. All the specs and parameters were copied to ensure similar sound and physical fit. Same impedance (6 ohms), face plate and screw holes, so you do not have to modify the cabinet at all.
Pioneer speaker models:
– HPM-40, HPM-50, HPM-60, HPM-70, HPM-100, HPM-150 and more. Will not fit all versions, some of the later models use a different tweeter. Make sure the tweeter part #’s are the same before ordering.
Pioneer tweeter part #’s:
– 45-711A-1, 45-711A-2, 45-711A-3, 45-711B-1, 45-711C, 45-713A and more.
This tweeter is also a good replacement for the 45-717A-1 and 45-717A-2 tweeters used in the HPM-500, HPM-700, HPM-900, HPM-1100 and more speakers. Physically it has a little smaller face plate and the screw holes don’t line up perfect, so some modification is needed.
