used these to replace the rear speakers in my 525i. These speakers have a nice crisp sound and it carries itself to the front well, especially those crisp hi-hat patterns in southern rap music. I like them alot, although its ability to achieve nice deep bass is limited by its size and enclosure from the stock speakers. Very good speakers if you want the crisp highs from a set of 2 way speakers and overall really nice quality in sound.
