Product Details

GRS PZ1005 3-1/4" Piezo Horn Tweeter Similar to KSN1005A

The GRS PZ1005 is specifically designed and engineered to be a replacement for the very popular KSN1005A piezo tweeters from days gone by. Using a 22 mm ceramic piezo element, GRS piezo tweeters follow CTS' original recipe and are far superior to most look-alike piezos.

With a wide frequency range and ample power handling, this is also a prime candidate for new designs, especially if the crossover requirements must be kept to an absolute minimum. 

Specifications: • Power handling: 50 watts RMS/75 watts max • Frequency response: 4,000-27,000 Hz • SPL: 94 dB 1W/1m • Dimensions: A: 3-1/4", B: 3-1/16", C: 2-1/2".

Rated 4 out of 5 by from fixing my old rca 3 way speakersi bought these about 6 months ago to replace some old and bad tweeters that plastic and were fake and did not work in a pair of RCA bookshelf 3 way bass reflex speakers model RS2664 that i got free from a friend and also i bought a capacitor for this to tweak the highs and make it less harsh on the vocal notes here the link for the capacitor https://www.parts-express.com/33uf-100v-electrolytic-non-polarized-crossover-capacitor--027-328update on speakers i just replaced the thin red and black wire that came with it with some pyramid 18 gauge speaker wire that i had hanging around. and the last thing i will be fixing or redoing to the speakers i believe by scraping off the old black veneer sand that down with 80 grit sand paper then finish it off with 120 grit and what i also plan to do is either fill in the dings and dents from the previous owner with wood putty and make it all smooth and original like new then after that is all done i plan to spray pain all the sides of the wood with black paint and be done with that for now and hopefully that last thing i will do is patch the small speaker wire hole on the back and fill it with wood putty and buy and circle speaker terminal cup on here and be done with that for now i hope. but i think overall when these speakers will be done and fixed up to the most that i can do to them will look pretty awesome and sweet for the finished product and since i got these speakers for free i most likely will be selling these at a garage sale for like 25 dollars along with my kenwood stereo i also got free from my friend.

Rated 2 out of 5 by from RECOMMENDED (WITH CONDITIONS)OK, the conditions are, if you really liked the original Motorola piezo tweeters, you'll probably like these. I bought them to get better highs from an old pair of Radio Shack speakers that sounded relatively dull (to my ears) and, since they were only $2 apiece I got a few extra. I found the piezo's response was most prominent in the lower part of a typical tweeter's range, around 4kHz, not in the 8-16kHz range I was expecting. But they are very efficient and in many relatively non-critical applications they may fit the bill perfectly.

What is the ohm rating on these? Also do you think these could be an ok replacement for a Bass Guitar cab?

Asked by: thebassbuilder
Piezo tweeters do not have an impedance rating. These will work fine for a bass guitar cab.
