Cicada Audio CM69.2X – 6×9" Carbon Matrix Mid-Bass Motorcycle Speakers (2Ω)

What's Inside the CM69.2X

The mid-bass cone is Carbon Matrix Composite™ (CMC™) – lightweight, rigid, and thermally stable under sustained high-output operation. The 2.0-inch / 51mm Black Coat™ OFC copper voice coil handles sustained 250W RMS with high conductivity and low thermal resistance. As a dedicated mid-bass driver with no tweeter to divide the signal, the cone operates across the full mid-bass range – the CMC™ material's stiffness keeps its resonant characteristics consistent across extended use in the saddlebag lid environment. On the road: defined, consistent mid-bass from the saddlebag lid position across a full day's riding at output.

The OFC copper shorting ring is mounted in the motor gap – a conductive sleeve that counteracts the voice coil's inductance variation as the coil moves. The effect is a reduction in second and third harmonic distortion (which a fluctuating inductance otherwise generates) and a flatter impedance curve at higher frequencies, extending usable response beyond what the driver would achieve without it. In a component system where the crossover point is set in DSP, the shorting ring's distortion reduction is most audible in the upper mid-range – the frequency band that carries vocal presence and instrument body. On the road: cleaner upper mid-bass from the rear stage – the frequencies that push through road noise and keep the rear fill from sounding congested.

The motor is an N35SH neodymium with H-grade temperature rating. The die-cast aluminium basket with Vortex Flow Venting™ channels airflow through the motor assembly for active thermal management. No external crossover is included or required – the CM69.2X is designed to be driven via a DSP active crossover or passive component network at the system level.

Sensitivity and Frequency Coverage

At 94 dB (1W/1m) and 250W RMS, the CM69.2X delivers rear-stage mid-bass output that exceeds the efficiency of the CHX69 coaxials in the same position by 2 dB. The difference is meaningful in the saddlebag lid position where the rear stage output target is set against a front stage and ambient highway noise: 2 dB less amplifier effort for the same perceived level. Frequency response runs 70 Hz – 10 kHz (±3 dB) – the appropriate range for mid-bass operation in a component system. In an active DSP setup, the crossover point to the companion tweeter is typically set between 3 kHz and 8 kHz depending on the tweeter used.

Why 2Ω – Amplifier Pairing

At 2Ω, the CM69.2X extracts full rated output from any 2Ω-stable motorcycle amplifier. For active DSP builds, the FLX700.4PRO and FLX1400.4PRO provide DSP crossover control and dedicated amplifier channels for both mid-bass and tweeter from a single unit. For high-output stereo builds without DSP, the FLX1400.4 and FLX2000.4 publish their rated output at 2Ω stereo. For bridged configurations, the CM69.4X satisfies the 4Ω minimum load requirement.

Fitment

• Designed for 6×9-inch saddlebag lid speaker positions – the primary rear speaker location on Street Glide and Road Glide models with factory or custom saddlebag lids.
• Saddlebag lid positions: Direct-fit for factory and aftermarket saddlebag lids with 6×9-inch speaker cutouts. The standard rear stage position on Harley-Davidson® Street Glide and Road Glide platforms.
• Custom enclosures: Any custom-fabricated speaker enclosure designed around the CM69.2X's 5.7×8.5-inch mounting footprint and 3.26-inch depth.
• Mounting Depth: 83 mm (3.26 in). Mounting Dimensions (cutout): 145 × 216 mm (5.7 × 8.5 in).
• No external crossover required – designed for active DSP systems or passive component crossover at the system level.
• Requires a dedicated external amplifier – FLX700.4PRO, FLX1400.4PRO, FLX1400.4, or other 2Ω-stable motorcycle amplifiers.
