Performance Piezo Tweeters Audio Frequency Review

The speaker worked for a few seconds but then lit up and stopped working. I just hooked up a 100w amp to it and used a tone generator to create sound, it wasn't even loud enough to hurt. These speakers have wires so small that 400 watts will easily melt the wires. You get what you pay for, that's rubbish.

When unpacking, the PVC carrier plate came loose on both speakers, as well as the first weld inside the speaker, where the cable was attached to the positive pole. You…
