Cicada Audio CM8.4X 8-Inch 4-Ohm Mid-Bass Component Speakers (Pair)
The Cicada Audio CM8.4X 8-in, 4 ohm mid-bass component speakers combine Rain or Shine all-weather design with Carbon Matrix Composite cones for motorcycle audio systems. Sold as a pair, they offer published power handling of 250W RMS/500W MAX, 94 dB sensitivity at 1W/1M and a frequency response of 70 Hz - 20 kHz +/- 3 dB. Black Coat-treated OFC copper voice-coil wire adds a focus on conductivity and thermal performance, complementing the cones' low mass, strength and high-temperature resistance.
Key Features
Rain or Shine All-Weather Design
Rain or Shine construction addresses the outdoor setting of motorcycle audio. As you plan the rest of the system, use the 4 ohm driver impedance and published 250W RMS/500W MAX power-handling specification as starting points.1
OFC Copper Shorting Ring for Upper-Frequency Extension
An OFC copper shorting ring is designed to extend upper-frequency performance. When comparing drivers for your system, consider the specified 70 Hz - 20 kHz response together with its +/- 3 dB tolerance, rather than looking at the frequency endpoints alone. The sensitivity specification also supplies a defined measurement reference: 94 dB at 1W/1M.
Carbon Matrix Composite and Black Coat OFC Copper
The cone material balances several priorities at once: keeping mass low while retaining strength, efficiency and resistance to high temperatures. A 2.0-in voice coil complements that construction with Black Coat-treated OFC copper wire selected for conductivity, low resistance and thermal performance.
N35SH Neodymium Motor and Vortex Flow Venting
A custom die-cast aluminum basket incorporates Vortex Flow Venting alongside the N35SH neodymium motor. For installation planning, check the 2.8-in mounting depth and 7.1-in mounting diameter against your intended speaker location; these are mounting measurements, not overall speaker dimensions.
