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. 

Specifications: • Power handling: 200 watts RMS/400 watts max • Frequency response: 1,800-30,000 Hz • SPL: 92 dB 1W/1m • Dimensions: A: 4-1/4", B: 4-1/16", C: 3".

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.

Rated 3 out of 5 by from Worth the money.I tested and installed the speakers hoping that it will expand the frequency spectrum. In testing (i.e., without crossover filters) all I heard was basically harmonics and sub-harmonics (which are signal distortions) in the 10KHz - 15KHz range. Hence, the claim that the frequency response is 1.8KHz to 30KHz is only accurate to the extent it doesn't mean that the response is flat or near flat throughout the frequency range. It can vary/fluctuate by as much as 50dB and the claim can still be made that there is a response . Further, to the extent that virtually no manufacturer or seller advertize or make available information about frequency response, then we are always "buying the cat in the bag". We are never in a position to make informed product selection. This is the very situation that forces customers to hedge their bets by basing their buying decision almost exclusively on price.
