The ARC Audio X2 402 is a precision-engineered 4" coaxial speaker designed for installations where space is limited but performance can’t be compromised. Whether you're upgrading a factory system, restoring a classic car, or integrating into a custom aftermarket build, the X2 402 delivers rich, dynamic sound in a compact, OEM-friendly footprint.

At its core is a glass fiber-reinforced polypropylene woofer cone, purpose-built for clean midrange and tight midbass—even in confined door or dash locations. A butyl rubber surround maintains mechanical stability across extreme temperatures, ensuring lasting performance in daily-driven vehicles or demanding environments.

High frequencies are handled by a compact 20mm silk-dome tweeter with an integrated phase plug and powerful neodymium motor. The result is crisp, natural highs with excellent off-axis response—essential for dashboard or low door-mount applications.

Each speaker features an integrated 12dB/octave crossover network using audio-grade polypropylene capacitors for seamless frequency blending and long-term reliability. Backed by ARC Audio’s in-house thermal validation process, the X2 402 is tested to exceed expectations for durability, voice coil integrity, and overall stability under real-world conditions.

Ideal for vehicles that require 4" speaker solutions—new or old—the X2 402 proves that small doesn’t have to mean compromised.
