Review: Excellent product, excellent sound quality with blaupunkt single din stereo
Review: Bought this pair as replacement for factory installed speakers on W212 Benz. Packaging was good, came with warranty papers. These coaxials sound good. Bass is good although not the loudest as I dont have any subs or crossovers setup in my car. Went with Sony at front (slight bright sound) and these Infinity at rear doors along with in-built factory tweeters. Now i have 4 speakers and 8 tweeters setup
