Cicada Audio CH8.4W — 8" All-Weather Horn Coaxial Motorcycle Speakers (4Ω)
Cicada Audio CH8.4W — 8" All-Weather Horn Coaxial Speakers for Harley-Davidson Motorcycle Audio Systems (4Ω)
A hard-hitting 8” horn-loaded speaker built for riders who want huge rear-stage output, strong midbass and long-distance durability.
The Cicada Audio CH8.4W is an 8-inch all-weather horn coaxial engineered for saddlebag pods, side panel pods and tour-pak speaker housings. Its 4Ω impedance makes it amplifier-friendly, while its treated paper cone and aluminium horn tweeter deliver outstanding clarity and projection — even at highway speeds.
Designed for harsh motorcycle environments, the CH8.4W uses a weather-resistant cone, N35SH neodymium motor and external crossover for a powerful, controlled and highly reliable rear speaker upgrade for Harley-Davidson Touring models.
Key Features
- All-weather construction: Water-resistant cone, sealed motor design and corrosion-resistant materials.
- 8" high-output driver: Large cone area delivers heavy midbass and big-stage presence.
- 4Ω impedance: Works with most motorcycle amplifiers.
- Aluminium horn tweeter: Crisp, long-throw highs that cut through wind and road noise.
- External 12 dB crossover: Includes optional -3 / -6 dB tweeter attenuation pack.
- Motorcycle-ready durability: Built for vibration, heat, rain and long-distance abuse.

| ⚠️ IMPORTANT – Crossover & Setup Requirements (Read Before Installation) | |
|---|---|
|
All horn speakers have mechanical limits. Regardless of power ratings or advertised “MAX” figures, a speaker can only move so far before mechanical failure occurs. Most horn speaker failures are NOT burned voice coils. In real-world motorcycle installs, damage is typically caused by over-excursion — the speaker moving too far because it is crossed over too low. This leads to tinsel leads tearing away from the voice coil or spider. Once this happens, the speaker is permanently damaged. |
|
Required High-Pass Crossover Settings
Lower crossover points WILL cause distortion and speaker damage. |

Saddlebag & Pod Installations – Critical Note
When using 6×9 or 8-inch Pro Mid-Bass / Horn drivers inside saddlebags, internal air volume is limited. Cicada Audio strongly recommends the following DSP settings:
Never run these speakers full-range. |
|
Amplifier & Wiring Setup Notes
Always high-pass coaxial horn drivers. |
