Cicada Audio CXX57.4 — 5x7" Bi-Ampable Motorcycle Coaxial Speakers (4Ω)
Cicada Audio CXX57.4 — 5x7" Bi-Ampable Coaxial Speakers for Harley-Davidson Motorcycle Audio Systems (4Ω)
A flexible, high-performance 5x7” coaxial built for Harley Touring riders who want clarity, power and OEM-grade integration.
The Cicada Audio CXX57.4 is a bi-ampable 5x7-inch coaxial speaker designed specifically for motorcycles. It can run as a traditional full-range coaxial on a single amplifier channel, or in bi-amp mode with independent woofer and tweeter channels for advanced DSP tuning and maximum output.
True Drop-In Replacement for Harley-Davidson CVO Boom! Stage II Rear Speakers
This is one of the only aftermarket 5x7" speakers that directly replaces the bi-amped Harley-Davidson Boom! Stage II rear speakers found in CVO Touring models—no adapters, no rewiring, no compromises.
- Bi-ampable inputs: Separate terminals for the woofer and tweeter, matching OEM Boom! Stage II architecture.
- Direct plug-in for CVO harnesses: No rewiring, no soldering, no converters required.
- Coax switch: Use as a full-range coaxial if your bike isn’t bi-amped.
- Big upgrade in efficiency and clarity: Much stronger performance than factory CVO speakers.
This makes the CXX57.4 the #1 choice for CVO riders wanting a simple, factory-style upgrade with dramatically better audio performance.
