Piezo Source manufacturers the Powerline Series to the exacting production, process and material specifications developed by Motorola. High Impedance Piezoelectric TransducerĤ00 W Powerline Series Piezo Source is the owner and manufacturer of the original Motorola 400 W Powerline Series.This tweeter sounds much better than the old T35 too. I have been able to get 104dB/2.83V/1M out of a single KSN1016 ☑dB from 4Khz~16Khz, rising another 2dB at 20Khz.

#Cts piezo tweeter driver

This is the opposite of a driver with a voice-coil, they are inductive, so the Zobel has a capacitor in it. The actual increase depends on factors such as off-axis angle, frequency, tweeter model and the configuration of. Each time the number of tweeters connected in parallel is doubled, the average sensitivity for the array increases by 3 to 6 dB. Since the piezo is capacitve the Zobel will have an inductor in it. CTS piezo tweeters allows several units to be connected in parallel without overloading the amplifier. For this reason it is best for piezo tweeters to have an 18dB/oct minimum roll-odd rate, the bender element provides 6dB of this by being a capacitor, the extra 12dB or more must be provided by the user.Ī Zobel must be used to keep the impedance presented to the crossover reasonably flat. Music program material content also goes up at a 6dB/oct rate as the frequency goes down, it flattens out below about 250hz. If it made noise, they sold it.įor constant amplitude output as the frequency goes down, diaphragm motion goes up a a 12dB/oct rate. Motorola screened all tweeters in house, the problem was that 'fall-outs' still got sold, just at a reduced price. Some companies trying for high quality sound actually took the tweeters apart and added a paper spacer ring to increase the clearance. Motorola was obsessed with having a bunch of output in the 20Khz region so they ran very tight spacing on the phase plugs. The high voltage from the low frequency can also cause cracks to develop in the piezo bender element, they sound very wierd after they crack. Low frequency causes intermodulation distortion, and in severe cases, the diaphragm can hit the phase plug. I usually use values in the range of 47R~100R/2W, this also takes care of the amplifier instability problem too. Adding a series damping resistor de'Q's the resonance in most models that this is OK. The un-damped tweeter drive element itself has a 'ring' mode. This tends to make the high end sound like an electric shaver, 'metalic' or 'buzzy' sounding. These amplifiers become unstable driving this much un-damped capacitance on their outputs and tend to 'ring' on transients. Many cheap speakers had a half dozen of these all in parallel, a load of anywhere from 0.5♟~1.0♟ It is popular these days to omit the output inductor in amplifier designs, Adcom is just one such example. They really do, and the more complex the crossover is, the better the tweeter can sound.Īnother big issue is amplifier stability. We could actually be lisening to the same piezo tweeters.įoremost is probably the fault of Motorola for saying these don't need a crossover. Presumably - based on djk's comments - the better units do not exhibit that behaviour." "My biggest issue with the piezos I have heard is that they sounded strident and had an almost metallic quality in the lower end of their range.

Persons wanting to know how to design proper crossover for piezo tweeters should do a search at: Trim the side next to the two screws first, otherwise you will need to clamp a 1 X 4 to the saw top as an auxillary fence to do the other side. Efficiency: 99 dB SPL ( Sound Pressure Level) 2.83V Input 1Meter. Impedance: Appears as a 0.26 uF capacitor. PRODUCT SPECIFICATIONS: Power Handling: 100 watts RMS / 125 watts MAXIMUM. The motor assembley of the piezo has three mounting screws, two next to one side, one next to the other. PRODUCT DESCRIPTION: Piezo elements requires no crossover. I do this on a table saw, tape over the horn opening to keep clean. The current KSN1016 mounting flange needs to be trimmed to fit the MCM1900 housing. Piezo tweeters require application specific crossovers to get the best performance, the MCM1900 has such a crossover. In a Klipschorn/LaScala/Belle the KSN1016 when crossed properly will work with a 200W amplifier, do you need more power handlng than this? The K77 will handle more power than the KSN1016 piezo, in every other way, shape or form, the piezo SMOKES the K77.

#Cts piezo tweeter movie

One favorite line I heard in a movie was 'better than sex', the woman's reply was 'maybe you aren't doing it right'. These items are shipped from and sold by different sellers. 799 (0.80/Item) Total price: Add both to Cart. Taiss 10pcs SPDT Mini Toggle Switch 3-Pin 2 Position ON/ON Miniature Toggle Switch 6A 125V AC Toggle Switch MTS-102. Well spoken by someone that has probably heard neither version of the MCM1900. This item: CES PIEZO Tweeter 3 3/8' Square Flush Mount. The k77's, of course, sounded a LOT better!!" "Yes, Klipsch did use the piezo tweeters, as well as K 77's(not sure but feel this is right the real deal in the K horns) in the high end pack for the MCM system.
