30-ohm resistor necessary for a piezo tweeter when using a crossover? I'm using three-way crossovers. Do I still need some for the piezo tweeters?

Making Piezo Tweeters Sound Better Making piezo tweeters sound better! • • • Adding a series resistor greatly improves most uses of piezoelectric tweeters.

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. Lower treble frequencies are less affected, but the effect is great enough to consider the sensitivity reduced by 1 dB or maybe slightly more. Download Patched Counterstrike Source. If the effect is not enough to tone down the 'hissy' nature of most piezo tweeters, then use a slightly higher value resistor. However, you should not have to go over 100 ohms, since this has quite an effect on upper treble frequencies. The KSN1025 tweeter and its relatives (including Radio Shack 40-1379) have an internal resistor of 30-33 ohms.
