The SDX 6.5" 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
The polypropylene (P.P.) injection cone with a cloth edge resists moisture and UV damage better than paper cones, making this speaker suitable for doors, rear decks, and even marine-adjacent applications (golf carts, UTVs) where humidity is a concern. The 10-oz magnet provides stable motor force without requiring massive mounting depth.
With 4Ω impedance and a moderate 89 dB sensitivity, the SDX is designed to play loudly and clearly on factory radios (15–25 watts RMS), while the 250-watt maximum rating assures buyers that the speaker can also handle an aftermarket amplifier later.
The SDX 6.5" 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
