Cicada Audio 5.25-Inch Pro 4-Ohm Coaxial Horn Speakers (Pair) - CHX525.4

Cicada Audio CHX525.4 5.25-Inch Pro 4-Ohm Coaxial Horn Speakers (Pair)

Cicada Audio CHX525.4 is built for enthusiasts and installers seeking high-output performance from a pair of 5.25 in pro coaxial horn speakers. This 4-ohm configuration handles 150W RMS and 300W maximum power, giving custom vehicle and motorcycle audio systems a purpose-built balance of output and efficiency. Rain or Shine all-weather engineering supports exposed or weather-prone placements, while the exclusive Nanofram horn-cover design reinforces the speaker's weather-conscious construction.

Every part of the coaxial driver system contributes to a strong, efficient presentation. The aluminum tweeter diaphragm brings a brighter high-frequency character, and its 1 in OFC copper-wire voice coil is engineered for robust sound with controlled heat generation. A Carbon Matrix Composite cone gives the mid-bass section a lightweight yet rigid foundation, while the black-coated OFC copper-wire voice coil combines high conductivity with low resistance for demanding thermal conditions. An N35SH neodymium magnet supplies a compact, high-strength motor, and the custom die-cast aluminum basket incorporates Vortex Flow Venting to move air through the assembly.

The CHX525.4 is rated at 91 dB sensitivity at 1W / 1m and delivers a 90 Hz-20 kHz frequency response at +/-5 dB. Its external 12 dB crossover is custom-tooled, vented and encased to coordinate the tweeter and mid-bass sections within the coaxial horn system. Together, the specialized materials, all-weather approach and crossover architecture make this speaker pair a capable choice for a carefully tuned high-output installation. Setup should follow the designated crossover routing and driver-protection guidance.¹

Key Features

Nanofram Horn Cover

Cicada Audio's exclusive cover is designed to help keep rain away from the horn, adding targeted protection for vehicle and motorcycle systems installed where weather exposure is a concern.

Carbon Matrix Composite Cone

The CMC cone combines low mass, rigidity and heat tolerance. This material profile is intended to preserve structural strength while helping the mid-bass driver use power efficiently.

High-Temperature Voice-Coil Design

OFC copper-wire conductors serve both driver sections. The tweeter coil is designed to reduce heat generation, while the black-coated mid-bass coil emphasizes conductivity, low resistance and operation under extreme temperatures.

Vortex Flow Venting

The rigid custom die-cast aluminum basket integrates a dedicated airflow design to support thermal performance around the driver assembly.

External 12 dB Crossover

A custom-tooled enclosure protects the vented crossover, which manages the coaxial horn driver's tweeter and mid-bass connections as part of a properly configured system.

Footnotes:

¹ Connect both the tweeter and mid-bass driver through the crossover wiring arrangement, observe marked positive and negative polarity, and always high-pass coax horn drivers. Insufficient amplifier power driven into clipping can heat the voice coil; operating the driver below its resonant frequency can also contribute to failure.
