There’s high-end car audio and then there’s the MB Quart Q Series. This flagship line is the absolute finest to come from the house of MB Quart. The QSD 210 is completely hand crafted in Germany combining time honored craftsmanship with absolute cutting-edge engineering and materials. The QSD features a newly developed wet powder coated (WPC) cone of genuine titanium. This unique cone (quite frankly, there’s nothing like it on the market today) provides a extremely linear, musical response. The 1” Q Series pure titanium tweeter features a composite surround for improved linearity and shares much of the technology used in MB Quart’s $70,000 home speakers. Finally, the laboratory-grade BTT MUSiCOMP crossover network utilizes Balanced Temperature Technology to extract the best possible performance from the drivers.
