DS18 DXQ6C3
The DS18 DXQ6C3 is a premium 6.5-inch 3-way component speaker set engineered to produce detailed, full-range audio with strong bass, rich midrange, and crisp high frequencies for car audio enthusiasts looking to upgrade factory systems or build custom sound setups. This set includes two 6.5″ woofers, two 3.5″ midrange drivers, two 2″ dome tweeters, and two 3-way passive crossovers to precisely divide frequency bands for optimal clarity and staging. With a 4 Ω nominal impedance, 150 W RMS (300 W peak) power handling, and 90 dB sensitivity, the DXQ6C3 delivers efficient, distortion-free sound across a wide frequency response of approximately 35 Hz–20 kHz. The yellow straw + composite foam cones on the woofers and midranges provide durability and accurate sound reproduction, while the silk dome tweeters offer smooth, detailed highs. Designed with quality materials and precision engineering, this component set brings professional-level clarity and depth to your vehicle’s audio system.
