The SDX 5.25" 4-Way speaker bridges the gap between basic coaxial speakers and component systems. By adding a dedicated dome tweeter and a piezo super-tweeter, it targets listeners who find standard 2-way speakers lacking in vocal clarity and high-end airiness
The SDX 5.25" 4-Way Speaker delivers concert-like frequency range from deep bass to sparkling highs, engineered for drivers who want maximum sonic detail from a factory radio or aftermarket head unit
SDX covers low-end thump (down to 80 Hz) to beyond the audible range of human hearing. This makes it a direct upgrade from standard 2-way coaxial speakers, offering smoother transitions between bass, midrange, and treble.
With 88 dB sensitivity and 4-ohm impedance, these speakers play loud on factory power (15–25 watts RMS) but can handle peaks up to 220 watts max, allowing room for future amplifier upgrades.
