100w 6.5" Coaxial Set Thank you for purchasing the Ampere Audio 6.5sc Dream Series speaker system. The 6.5sc features an adjustable swivel 25mm silk dome tweeter that resides in a hardened plastic housing. The 6.5” midrange also features a single roll surround that eliminates unwanted resonances, acoustical artifacts and dampens mechanical vibrations. The tweeter and midrange have been specifically engineered with complex FEA analysis that perfectly optimizes the motor structures. Engineering a great tweeter and midrange is not enough to guarantee excellent sound quality so we added a touch of SQ dust.
