MB Quart FKB110 4" 2-Way 160 Watts Coaxial Speakers (Pair)

The ideal balance of a high-end car audio system requires the perfect mix of speaker tone, deep bass impact, and clean undistorted power. With MB Quart we make it simple to develop the impeccable Formula for a great sounding system. The Formula line offers a high-end sound quality through a full line of aluminum dome tweeters with polypropylene cone speakers. These components can be matched with 400-watt peak power, dual 4-ohm subwoofers to command the deep bass frequencies all powered by the Q-Stasis circuitry amplifiers in the Formula line up.
