The CM69.2X at 4Ω — for bridged channels and conservative builds.

The Cicada Audio CM69.4X is a 6×9-inch 4Ω mid-bass component speaker — 250W RMS, 94 dB sensitivity, Carbon Matrix Composite™ (CMC™) cone, OFC copper shorting ring, Black Coat™ OFC 2.0-inch voice coil, N35SH neodymium motor, and a die-cast aluminium basket with Vortex Flow Venting™. Frequency response 70 Hz – 10 kHz (±3 dB). Sold in pairs.

The CM69.4X shares every construction element with the CM69.2X — the same CMC™ cone, the same OFC copper shorting ring, the same 250W RMS power handling and 94 dB sensitivity in the 6×9-inch saddlebag lid mid-bass component format. The 4Ω impedance presents a higher electrical load to the amplifier: lower current demand, reduced thermal stress, and compatibility with bridged configurations where a 4Ω minimum load is required.

Who This Speaker Is For

For riders building active or component rear stages in 6×9-inch saddlebag lid positions who are running bridged rear channels, or who prefer the conservative 4Ω impedance for better thermal performance. The CM69.4X is the 4Ω variant of the CM69.2X — same driver, same performance, higher impedance. For dedicated 2Ω-rated amplifiers in stereo, the CM69.2X extracts maximum power.

What This Is Best For

• Active DSP builds with bridged rear mid-bass channels — when rear channels are bridged for maximum per-channel output, the CM69.4X satisfies the 4Ω minimum load requirement while delivering the same 94 dB output and CMC™ construction from the saddlebag lid position.
• Uniform 4Ω active system builds — for builds where consistent 4Ω impedance across every driver simplifies amplifier matching and reduces total system current demand.
• Conservative builds where the amplifier delivers sufficient power at 4Ω — when the amp's 4Ω rated output exceeds 250W per channel, the CM69.4X receives full rated power without requiring the 2Ω operating condition.
• Passive component rear builds where 4Ω suits the crossover network — some passive crossover designs are optimised for 4Ω driver impedance; the CM69.4X satisfies that requirement in the saddlebag lid position.

The Bottom Line

250W RMS, 94 dB, 6×9-inch mid-bass component with CMC™ cone and OFC copper shorting ring — the 4Ω version for bridged and conservative active or component rear stages in saddlebag lid positions.

Ready to build? Add to cart above. For the 2Ω variant, the CM69.2X is the same driver at 2Ω.

What's Inside the CM69.4X

The CM69.4X is identical in construction to the CM69.2X — all construction notes below apply equally to both impedance variants.

The mid-bass cone is Carbon Matrix Composite™ (CMC™) — lightweight, rigid, and thermally stable. The 2.0-inch / 51mm Black Coat™ OFC copper voice coil handles sustained 250W RMS. The OFC copper shorting ring in the motor gap reduces inductance modulation distortion and extends upper-frequency response — the 4Ω version provides the same shorting ring performance as the 2Ω variant, with the thermal and load benefits of the higher impedance. On the road: the same mid-bass character and clarity as the CM69.2X from the saddlebag lid position, with the amplifier running cooler on the rear channels.

The motor is an N35SH neodymium with H-grade temperature rating. The die-cast aluminium basket with Vortex Flow Venting™ manages heat through active airflow. No external crossover is included — designed for active DSP or external passive crossover at the system level.

Sensitivity and Frequency Coverage

At 94 dB (1W/1m) and 250W RMS, the CM69.4X matches the output of the CM69.2X — impedance changes amplifier compatibility, not speaker performance. Frequency response runs 70 Hz – 10 kHz (±3 dB). The 4Ω impedance means the amplifier draws less current on the rear channels — in an active build where all channels share one amplifier, 4Ω rear drivers give more thermal headroom across the system.

Why 4Ω — Bridged Amps and Thermal Margin

A 4Ω driver presents a higher electrical load than a 2Ω driver — lower current demand, less heat, and compatibility with bridged configurations. For DSP builds where rear channels are bridged for maximum per-channel output, the 4Ω load satisfies the minimum impedance requirement on amplifiers including the FLX700.4PRO and FLX1400.4PRO. For stereo installs at the amp's rated 2Ω output, the CM69.2X is the matching choice.
