I just received my shipment of 8 drivers, put one (mono) in a flower pot, held it in with masking tape, and connected it to a old receiver with FM radio, and turned it on. For 87 cents, it sounds great. There is some bass potential, especially with multiple drivers. The quality is very good for the price. The ONE driver (again, mono in a flower pot right now), it goes loud, and very clean. In the sealed pot, the bass is very controled (so I won't blow it up) The first thing I was on was a Mexican radio station, and some guy was requesting a song. You could hear he was on a bad telephone line, and there were people taking in the background - while you could clearly hear the DJ AND the music playing in the background. I might order another 8 tonight so I have a matching set.
