If you find a tweeter harsh you should consider switching to a cab that uses a midrange driver rather than a tweeter. However, if the midrange is still operating at the turnon of the tweeter 4 khz in the case of the super horn, a harshness may be heard in the total system. It is attached to an acoustic horn, a widening duct which serves to radiate the sound efficiently into the air. For the smaller piezo units that cut off at 45 khz, a series cap of 1. Adding about a 47 to 50 ohm or so resistor reduces the extreme treble response by about 3 db at 20 khz, and by about 2 db at 16 khz.

Mar 30, 2020 a piezoelectric tweeter is a type of audio speaker built to generate highfrequency sounds. While such designs possessed very high sensitivity, sound quality was largely. I am partial to fabric soft domes silk, in particular because they sound very smooth without being harsh.
Great deals on unbranded pro audio speaker horncompression drivers. Whats the difference between a horn and a tweeter, or are they the same. Horns are used for two purposes to control dispersion, and to couple the tweeter diaphragm to the air for higher efficiency. Im not a piezo tweeter expert, but my understanding is the main problems are a nonflat response over their active range, and also peaky nasty resonances within the range. It does color the signal, but in pro audio this is well worth the gains in output. No, technically piezo tweeters do not require a crossover. The tweeter is the one thing that gives a speaker its high frequency character, and is usually one of the things you will notice first. Choose the best matching replacement or upgrade with a higher quality driver to fit your repair project or next custom design. The piezo tweeter does not require a crossover network.
