Product Details

GRS PZ1188 Piezo Horn Driver Similar to KSN1188A

The PZ1188 is specifically designed and engineered to be a replacement for the very popular KSN1188A piezo horn drivers 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.

Standard 1-3/8" 18-TPI threads facilitate use with 1" horns. 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. This 100 watt driver incorporates advanced protective circuitry which allows it to be used at power levels of up to 400 watts.

Specifications: • Power handling: 400 watts max • Frequency response: 800-20,000 Hz • SPL: 93 dB 1W/1m • Dimensions: Diameter: 3-7/8", Depth: 3".

GRS PZ1188 Piezo Horn Driver Similar to KSN1188A
GRS PZ1188 Piezo Horn Driver Similar to KSN1188A is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from GRS PZ188 Great for 12" MonitorAfter replacing diaphragms twice on a set of Peavy 1-12" floor monitors...I finally decided to try something different. I wasn't sure if I'd like the sound of these oversized piezo drivers but they actually sounded better than I expected. Time will tell how they hold up. For the money, I don't see how you can go wrong with these.

Rated 5 out of 5 by from Rock band P.A.I put these (no crossovers, Goldwood GT 400pb and Selenium HM17-25 horns) in boxes with 10 and 12 inch Eminence Beta A series drivers. (approximately 2 and 3 cubic feet). These are supposedly 93db and the woofers are supposed to be around 97dbs. Luckily I have an EQ on my mixer because the piezos were a good 6 dbs louder. With their lower than average frequency response, the whole vocal spectrum seems to be fairly well covered.Good for vocals and guitar, but definitely needs a sub woofer and major EQ for any kind of fidelity in the way of recorded music playback (at least with this set-up).I've only had these a couple of weeks so I can't comment about their durability. So far they've held up to being pushed fairly hard by a QSC 1450 (450 watts into each stack)For what I'm using them for...would definitely recommend.

Using a piezo driver wth a x-over

If I am going to use a piezo driver in a system with a 3 way passive x-over should I wire a resistor parallel to the piezo?
Asked by: dodaddio
Yes you will want to wire an 8 ohm resistor in parallel with the driver.

Appropriate horn

Can this driver be used with a GRS PZ1025 2" x 6" horn?
Asked by: Mark Andrews
I used the Goldwood GT-400PB and Eminence Emitter EM:200S horns in my PA application. They're the only ones that I tried, so I can't give any comparisons. I haven't taken any sound measurements, but, for my requirements (Rock Blues Band), they seem to do the job well enough.

Can I use this tweeter and achieve good fidelity in the following configuration? See additional details.

2 class D amplifiers 1 powering a sub woofer the other powering a mid/tweeter coaxial. (Mid driver is Beta-8CX with this tweeter).I would integrate the Berhinger Ultra Drive as a 2way x-over and assume the tweeter can be properly attenuated with a resistor orL pad.If this makes sense any suggestions for passive tweeter control would be helpful.
Asked by: Footer
These will work fine for the application but fidelity is a matter of opinion. There are many people who like the sound of piezo tweeters and many others don't. For an inexpensive high frequency option they are hard to beat. If you want to use an L-pad with this, you will have to wire an 8 ohm resistor in parallel with the piezo and any 8 ohm L-pad will work.

Does this driver have the same protection circuitry as the orginal Motorola/CTS design?

The original design used a protection circuit with a resistor and thermal breaker paralleled with a tiny light bulb. Does this design have any protection circuit at all or is it just the piezo element?
Asked by: windeguy
This driver does have built in protection similar to the original CTS driver.

According to the specs shown, this driver's frequency response picks up at 800 Hz. That seems awfully low for a piezo. Is that correct or a typo?

Asked by: jgrammon
That is likely factoring in the Fs of the driver. I would not cross this any lower than about 1,500 Hz.
