Product Details

GRS PZ1165 4-3/8" Piezo Horn Tweeter Similar to KSN1165A

The PZ1165 is specifically designed and engineered to be a replacement for the very popular KSN1165A 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.

GRS PZ1165 4-3/8" Piezo Horn Tweeter Similar to KSN1165A
GRS PZ1165 4-3/8" Piezo Horn Tweeter Similar to KSN1165A is rated 3.125 out of 5 by 8.
Rated 1 out of 5 by from Poor Replica of a MotorolaBought 4 of these, and all are very poor in QUALITY. They look good, but that's as far as it goes.I always put some poly fill inside the cavity where the (Piezo) element is to kinda smooth out the response. This VOIDS the warranty I'm sure, but, at the price, I didn't care.So, in opening these, EVERY single stud where the screws go into to hold the backs on, were cracked. I also noticed that the casting of the horn part is VERY rough. I had to trim every opening (on the horn body) to get the openings clean of "slag" plastic. Also' 2 of the 4 didn't have the piezo disk centered on the cone, so I'm sure this will affect the output. Even the back cover doesn't fit tight.Overall, just poor Quality control. Now I know why they're so cheap. I wanted to use these as a rear tweeter on some boxes I have. I'll still try them out as this is an experiment, but the speakers will do garage duty.

Rated 5 out of 5 by from replacement tweeterI have a old set of 3 way cabs. I push them to their limit most everytime I use them, this is the third time I've replaced original parts with parts express replacements. Always a great experience, never a disappointment.

Rated 4 out of 5 by from Great tweeter for the money!I installed these tweeters in some full range DJ cabinets to brighten up the sound. The piezos were a little too loud on their own so I added an 100 ohm 1 watt metal film resistor and wow. Handles high power with no issues also.

Rated 1 out of 5 by from Ears still ringing......This tweeter is way too harsh for any application...period! I originally bought these for cheap replacements for my house speaker's blown Piezo. couldn't even sit in the same room with them playing. they sounded like they were only playing the background of the music....So I decided to do a DJ gig with them since they were so loud, had to cross them over in the mids bandwidth to even make them somewhat tolerable but they where still too much treble for me, even in a DJ situation...ready to trash them and get a decent pair of horns, good thing they are cheap!

Rated 4 out of 5 by from Good Motorola subIts an (Ugh!) piezo tweeter what can you say for them other than if your bad speaker has a piezo than this is the obvious choice for 10 times less than similar from other places.

Rated 2 out of 5 by from Hiss and SizzleOverly harsh tweeter for my tastes. Even with greater resistance its presence was too strong.
