Rated 4 out of 5 by from Perfect fitGot these to replace in a Nady 12" floor monitor and a Kustom 15" floor monitor worked great spot on matched exactly what came out. One did come wiht a broken connector but customer service replaced it FAST !A++ service.

Rated 5 out of 5 by from A VERY good value!! (decent replacement in a Peavey 115HC 2-way)I'll try to be as objective and helpful as I can in this review... This is a surprising little tweeter! Do yourself a favor though and make sure you have enough speakers to cover your venue. Too often people stretch 2 speakers on sticks too far, and then call them cheap when they fry. I actually fried a set of these last year doing stuff like that. Also you should use a crossover. I know, I know, "piezo speakers don't need crossovers". I'm not going there; we'll just say been there fried those. If a piezo receives too much voltage it actually will depolarize it's self, and therefore seem fried.CROSSOVER (simple yet perfect)If you want to know, a good crossover for a piezo can be put together for just a few bucks, and it will change the way you think about a piezo...-40 ohm resistor across the speaker leads-Then a capacitor in line with the positive terminal, just like a regular tweeter.Done!In case you want to know... The resistor keeps the amp protected from seeing the capacitive load of the piezo. The resistance is a higher value because the lower the value will waste more power, and also pad the tweeter more.The high-pass capacitor will protect the piezo from being over done by all the low frequency power in the signal and eventually burning out. They don't respond to low frequencies, but still sees them electrically. The cap also allows you to pick an actual crossover point that you can match up with your woofer, and not to mention the cutoff of the horn you use (the products I listed below would put you at a 2.5k x-over point- 40 ohms on a 1.5uf cap..)The SoundLike I said, I already ran these without this, they sound just OK without it, rather harsh as you would expect. With it however, these things actually sound like a real tweeter! Maybe they are?! They are a little on the quiet side to be matched up with a Peavey Scorpion, but the numbers tell you that. The combination makes for a smoother sound really. Still crisp and clear, not so biting. We'll how they do on an outing soon. I actually like the results much better than anticipated!. Far more musical than without a crossover (which is not not really fair to a tweeter anyways). I am listening to music on them right in fact. No studio monitors, but hey, for the money spent; FANTASTIC! These where supposed to be temporary for me, but I might find that I like having the option of a more tamed and natural sounding PA rig...For they money these are crazy good...I went off to do a few things before I submitted this review, and have had music playing on these at a decent volume for quite a while... uh, these things are really, (dare I say) nice sounding!

Rated 5 out of 5 by from Goldwood Bullet PiezoThese were the exact Piezo replacements required to repair the small PA cabinets I had. Works very well and great value!

Rated 4 out of 5 by from Good for the PriceHad to buy this for a repair project I was working on for a friend and his band. This driver sounds pretty much like the original, but since it used in a live situation you really can't tell the difference.

Goldwood GT-400CD Bullet Piezo Horn Driver

This is the horn driver I need but I would like one with more power than this one. I bought to of these before and they both have went completely out.

Asked by: The E
Unfortunately the highest powered piezo horn driver we have is 100 watts RMS.

Does this driver have the protection circuit that the original 1142 has (PZT and light bulb)?

Asked by: mbmtech
This does not have the protection circuit that was on the original power line piezos

Hi guys, will this piezo tweeter screw into the back of an eminence Beta 10-cx coax driver and no cross over ?

Asked by: The Jack Parrish Band
Yes this will screw into the back of the Beta Cx models and a crossover is not required.

100W of "highs" or overall wattage?

HiI am a bit confused by piezos and their wattage. If I put 500 watts into a 2x15 with a real crossover and a real horn, the voltage going to the horn is only a very small portion if the 500 watts.Is this how it works with piezos? Or if I put the same 500 watts into a cabinet with a piezo described as 60 or 100 watts or whatever, would that immediately burn out the tweeter? or does it only "see" the small portion of the signal over 2k (or whatever the crossover point is supposed to be). This would make a 100-watt piezo pretty happy in a 500-watt cabinet I would think. 1800 Hz is too low; 3K would be better for me, but I want a lens-mounted one. Would a cap of (value X) help?Thanks
Asked by: spezzo
Actually, most piezos are employed without a crossover and receive a full signal. That's partly the reason for their use in low and mid quality speaker cabs, they save money. They have no motor structure like normal drivers do. Basically the published wattage handling is for their overall frequency range. They are rated for 100 watts (rms) input over their stated 1800-30000 Hz frequency range. I have used them in my PA cabs, without a crossover, and powered by a Crown MA-5000i class I amp and they received a full signal with no problems whatsoever. You can, however, use them with a crossover if your cab already has them installed. Probably the best bang for the buck piezo out there.

what is the drivers max wattage

Asked by: speaker freack
The manufacture does not specify a max wattage for this driver, however you can figure double RMS. Max wattage is basically irrelevent, you don't want to put any more than RMS into a given driver.

What's the impedance of this tweeter?

Asked by: Cruz
KSN1142A spec sheet says :"Impedance: Appears as a 0.3 uF capacitor." This Goldwood tweeter is listed by Parts Express as similar to the KSN1142A piezo tweeter.
