Today's factory installed car audio systems are littered with poor speaker placement in a highly reflective environment that is not conducive to high performance listening. Replacing these speakers with higher quality aftermarket units can provide better tonal quality but proper staging and imaging is still compromised due to these poor speaker installations. In the past an elaborate and costly custom installation would be required to place the speakers in the proper location for optimum staging and imaging. With the introduction of MB QUART's new groundbreaking WideSphere™-Technology, those days are gone!

The heart of the WideSphere™ system is the new and unique tweeter QTF 40 used in the Q-Line and PTF 40 used in the Premium-Line with its inverted titanium dome and high performance neodymium ring magnet. An extraordinarily wide radiation angle, an extremely low resonance frequency and tremendous power handling combined with outstanding linearity are the result of intensive research, computer simulations and decade-long experience with ultra light titanium as source material for tweeter domes. The use of new materials coupled with exhaustive engineering and tuning time leads to a specially defined connection of cap and surround calculated to the closest tolerances and a result far ahead of our competition. The spaciousness, precision and power handling all contribute to the new tweeter's superb tonal balance in both on-axis and off-axis installations. Simply put, this is the most versatile high performance tweeter ever built for the car!
