The ARC Audio X2 502 is a versatile 5.25" 2-way coaxial speaker system designed to bring high-performance sound to vehicles with factory or aftermarket 5.25" speaker locations. Whether used as a drop-in OEM replacement or integrated into a custom install, the X2 502 delivers an immediate and noticeable upgrade in clarity, output, and tonal balance.

Engineered entirely in-house by ARC Audio’s team of acoustic specialists, the X2 502 is a ground-up design—not a rebranded generic driver. Its custom-tooled polypropylene woofer cone, reinforced with stranded glass fiber, delivers tight, punchy midbass with excellent control and reduced cone breakup at higher volumes. The durable butyl rubber surround and ventilated steel basket provide mechanical stability and cooling for consistent performance across a wide range of environments.

Atop each speaker sits a 20mm silk-dome tweeter with a neodymium magnet and integrated phase plug, tuned for a smooth, detailed high-frequency response with wide dispersion—ideal for dash or door panel installations. A built-in 12dB/octave crossover network with high-grade polypropylene capacitors ensures seamless tonal blending and long-term sonic integrity.

Thanks to its efficient motor structure, optimized suspension, and 4-ohm voice coil, the X2 502 performs equally well on factory head unit power or aftermarket amplification. Like every X2 model, it undergoes ARC Audio’s rigorous thermal and voice coil stress testing, ensuring long-lasting reliability in real-world conditions.

For installers and enthusiasts looking for a 5.25" coaxial that punches above its weight, the X2 502 is a perfect balance of fitment flexibility, premium sound, and ARC Audio heritage.
