Pyle Car Audio Speaker System 16.5 cm, 300 W Peak / 150 W RMS, 6-Way Full-Range Speakers with Piezo Tweeter, 8 Ohm Impedance, High-Power Car Stereo Speakers, Black Carpeted Enclosure

Brilliant product, i bought it as a gift for my friend and he was happy with the surround sound this speaker was able to deliver.

this unit is a gift at this price,Piezzo tweeters deliver what moving coils can't. High frequencies are very directional and don't travel.I connected one to my center unit and the enhanced top adds an incredible sparkle ,blending seemlesly.

I needed to increase the dispersion of frequencies above 8 kHz to around 17 kHz for pa use.The cabs look good and are built to a satisfactory standard but the advertised frequency response of 4 kHz~27 kHz isn't representative of the output I can measure from these.They struggle with anything above 10 kHz and sound more midrange with a little extra (unrefined) treble.The definition is poorThe end result is a very rough sounding mid range tweeter array.However the cabinets are built well enough to modify and replace the drivers for some reasonable tweeters -- and (were) cheap enough to buy as cabs alone.
