Anything with three pezio tweeters will take the top of your head off .Looks very cheeply made.See white van speaker
If the woofer is the the one I think it is, it's a fine driver.
Looks like it uses Motorola Powerlines, same as the Dahlquist DQ12. As the others have said, piezos can sound nice when used properly - I'm guessing you've seen inside these speakers then, since you know that it doesn't have a proper crossover?Those woofers is most likely not original , and the piezo are of an erea that the sound like lazer beams ,and don't have proper crossovers .
Am I the only one that thinks the "home/disco" switch is funny?
