These will handle up to 100watts RMS, and have a frequency response of 1,800 to 30,000 Hz.
Super easy to hook up -Piezos automatically roll off the low frequencies so you don't even need a crossover! Plus piezos don't put an ohm load on an amp so you can hook these up in multiples without worrying about amp loading.
These are a great economical way of putting together small PA, or monitor cabinets. Also great for Car boxes!
