Hello. I have Pioneer HPM-60 speakers and I'm not sure if the supertweeters work. Using just my ear and covering the mids and tweeters I can't tell if the supertweetes are working. In fact, I don't think they are. However, these HPM-60's have a really clean and detailed high end. Cymbals, Chimes, bells, etc. are distinct and clear and at regular listening volumes I would never think the supertweeters were not working. Anyhow, I bought a pair of supposedly working supertweeter replacements from Ebay but I still can't hear anything coming out of them.So, my questions are: Are the supertweeters extending beyond what I can hear? How can I test the tweeters to be sure they are working? Can I do this by checking continuity? If so, how do I do this. Thanks!

I was not giving you a BS answer. I have the Pioneer HPM 1500's with the stacked plastic super tweeter and there is simply no way I will ever hear them. If you do not know where your hearing falls off it might be worth it to find out. I can put in a test signal of 12k and turn the volume up all the way and hear nothing. I don't know if my super tweeter works and I guess I don't care.
find a test disc that goes out to 25 K or find a test occillater and use a SPL meter :) the rat shack meter will indicate the presence of signal out to 20 K reliably and is about 6 DB down @ 25K:)this is what i do
I also had a pair of Pioneer HPMs circa 1980. Can't recall which model, but it was one of the smaller ones. 8" woofer, paper tweeter, and possibly one of the super-tweets. Purchased from Lafayette for approx. $90. Now - more pertinent info to you...At this time, I also had a pair of ultra-resolving, highly musical Criterions (who the hell makes them anyway?) I purchased a pair of Rat Shack super-tweets to perch on top - possibly out of curiosity, or maybe boredom. I CAN remember hearing HF info coming out of them. Take the Super-duper tweet out and see if wires are attached. Not kidding - could have been a BS thing.
Good luck...
Seriously, can somebody please suggest a way to test a supertweeter. Thanks.
Borrow me for a day, I can hear it......lol, seriously though, it almost sounds like the high pitched sound that comes from a tv's power supply when u mute the tv or channel surfing. You're hearing it, you just aren't aware of it.
Cheap transistor radio, plus the earpiece (that you should throw away because its high spl's will make you deaf). Chop off earpiece, splay wires and connect to supertweeter, plug into radio on an AM station. Any functional supertweeter will work "fullrange" with such a signal so you should hear it - my test for STC/Coles 4001G's btw. Or connect a multimeter or nine volt battery across the terminals to get a d.c. "pop" - not indicative of full functionality. Finally for testing individual speakers (at a garage sale), get and build toy fire engine siren from an electronics shop, will drive all units well for ages but a complex crossovers may limit sound to a couple of seconds.

...now they do not even need to make anything that works, just call it super-whatever, and tell customer "well you can't hear this".
Very soon you will be buying super-ultra-high resolution system that plays only sounds above 2MHz. Due to newest super-ultra-light technology, all this will be soooo small that you will not even be able to see the system. So, for now we are selling useless plastic tweeters that do not work anyway, and in future we shall just take your money and give you the manual and warranty. We shall give you the system, but it is sooo ultra-super-small you cannot take it home by yourself, therefore it will be special delivery team ($10,000 for delivery). But hey if you do not pay this, you may lose your system on your way home and you won't know it, cause you won't see it anyway.
Laugh now, and cry when this happens to you.
I am deaf above 11k. The super tweeters are above that.
