MB Quart QSC216 Q Series 6.5? Component Speakers - Old school MB Quart QSC216 = QWC160 woofer + QTD25 tweeter + QXC216 crossover Bought in 2003, this was the last model year that MB Quart made quality component sets in Germany. After this, they were acquired by Rockford and started making $40 junk speakers. But from the early 90s to 2003, MB Quart ruled car audio door panels and the Q series was no exception. Q was a step down from their high-end speakers, yet combined some affordability with German engineering and exceptional build quality. These were used for 5 years until 2008, and then again from 2015-2018, and have been sitting in storage since. They work just fine and sound amazing. One of the tweeters does have a small dent in the cone as seen in one of the pictures. Also the silver woofer cones have some scuffs that are hard to see in the pictures. Its all cosmetic.
