Cicada Audio CXX8.4 — 8" High-Output Coaxial Speakers for Harley-Davidson Motorcycle Audio Systems (4Ω, 2" Voice Coil)
A massive, hard-hitting 8-inch coaxial built for riders who want extreme output and serious midbass from their rear stage.
The Cicada Audio CXX8.4 is an 8-inch high-performance Pro Coaxial speaker designed specifically for motorcycle audio systems. Featuring Cicada’s V8™ Dispersion Guide, a rugged Kevlar cone, PEI tweeter dome and a 2.0-inch copper voice coil, it delivers huge midbass impact, clear vocals and wide, 360° high-frequency dispersion — even at highway speeds.
Engineered around a compact N45H neodymium motor and a UV/heat-resistant polycarbonate basket, the CXX8.4 combines big-bike output with long-term durability in real-world riding conditions.
