Fix up Your HPM Speakers with Original Replacement Parts

Pioneer produced the HPM speaker series from 1975-1983. HPM was short for High Polymer Molecular, which was a new material used in the super tweeter (pictured).

If you have a problem speaker or blown out driver, the good news is that genuine replacement parts are often available for purchase. I've provided links below to many of the current ones up for sale.

The HPM Speaker series includes the following models:
HPM-30, HPM-40 (aka HPM-40/u1), HPM-50, HPM-60 (aka HPM-60/u2), HPM-70, HPM-100 (aka HPM-100/u1), HPM-110, HPM-110x, HPM-150, HPM-200, HPM-300, HPM-500, HPM-700, HPM-900, HPM-1100, HPM-1500

Does your HPM Supertweeter work?

Dead Super Tweeter, or Poor Hearing?

The super tweeter produces very high frequency sounds (depending on model, crossover may be 12kHz or 15kHz). If you can't hear the super tweeter, it could be fried, or it could just be that you have hearing loss. Here are some links with information on testing the super tweeter.

Anyone have ideas on how to test stereo speaker super tweeters?
I have a pair of Pioneer HPM-700 stereo speakers. I haven't found any official specs on these. They have tweeters and "glass prism supper tweeters" Any idea how I can tell if they work ? Using a test LP, I find my ears can not hear over about 10-12,000 hz. One website lists the crossover
