Cicada Audio CMB10.S4NEO — 10" Neodymium Motorcycle Mid-Bass Driver (4Ω, 800W RMS)

10″ neodymium mid-bass driver for Harley Touring — CMC™ cone, N42 NEO motor, 800W RMS with a weight-to-output ratio that ferrite can't match

The Cicada Audio CMB10.S4NEO is a 10-inch mid-bass driver built for high-output bagger systems where weight matters. The N42 neodymium slug motor delivers 800W RMS / 1,600W MAX power handling in a motor structure dramatically lighter than an equivalent ferrite magnet. The Carbon Matrix Composite™ (CMC™) cone adds rigidity without adding mass. The result is a 10-inch mid-bass driver that moves fast, handles sustained power, and doesn't weigh down the lid or enclosure that carries it. Sold individually.

The CMB10.S4NEO is the neodymium version of the CMB10.S4. Both drivers share the same 800W RMS rating, 4Ω impedance, CMC™ cone, 3-inch 6-layer Black Coat™ OFC voice coil, and die-cast aluminium basket with Vortex Flow Venting™ — the difference is the motor. The S4NEO uses an N42 neodymium slug where the S4 uses a conventional ferrite structure. If weight is a consideration — stretched lids, custom enclosures, Tour-Pak builds, or a bike where every kilogram counts — the S4NEO is the correct choice.

Who This Is For

Riders building a high-output 10-inch mid-bass stage on a Harley-Davidson® Touring model who need 800W RMS without the weight of a ferrite motor. The CMB10.S4NEO suits stretched saddlebag builds, Tour-Pak enclosures, and SPL-style systems where the full power rating is genuinely being deployed. If weight is not a constraint and you want the same output at a lower price point, see the CMB10.S4.

What This Is Best For

• High-output mid-bass in weight-sensitive builds — The N42 neodymium motor delivers the same 800W RMS / 1,600W MAX capability as the ferrite CMB10.S4 at a fraction of the motor weight. On stretched saddlebag lids and Tour-Pak enclosures, the weight saving at the motor is meaningful — less load on the lid hardware, better balance when the bags are open. On the road: a lid-mounted 10-inch driver that doesn't flex the hinge or load the saddlebag mounting points the way a heavy ferrite motor would.
• CMC™ cone for fast, accurate mid-bass to 1.8 kHz — The Carbon Matrix Composite™ cone is stiff enough to resist deformation at high excursion, lightweight enough to start and stop quickly, and weather-resistant enough to handle heat cycles, moisture, and UV. The 35 Hz – 1.8 kHz frequency response covers the full mid-bass band and hands off cleanly to a fairing or saddlebag tweeter. On the road: tight, accurate mid-bass at 110 km/h — no cone flex, no breakup at the top of the driver's range, no harshness when crossing to a tweeter at 1.8 kHz.
• 3-inch Black Coat™ OFC voice coil for sustained power — The 76mm 6-layer OFC winding maximises conductor cross-section in the gap, producing high current capacity and low DC resistance. Black Coat™ improves thermal conductivity between the coil and the former, allowing heat generated under sustained high-power use to conduct away from the gap more efficiently. On the road: consistent output over a long ride at high volume — not thermal limiting after 20 minutes.
• Vortex Flow Venting™ basket for active cooling — The die-cast aluminium basket uses venting geometry positioned to circulate air around the motor structure and voice coil gap as the cone moves. Combined with the vented voice coil gap and advanced heat-sink design at the motor, this produces active cooling that scales with the driver's output level. On the road: a 10-inch mid-bass driver that runs cooler under sustained heavy load — and maintains consistent sensitivity as the session extends.
• Rain or Shine™ all-weather construction — The CMC™ cone, motor sealing, and basket finish are designed for a motorcycle's environment: thermal cycling, humidity, rain, vibration, and UV. This is not a home-audio driver adapted for outdoor use — it is engineered for a motorcycle from the motor out. On the road: a speaker that performs identically in January cold and July heat, wet or dry.

Fitment

The Bottom Line

The CMB10.S4NEO is the right 10-inch mid-bass driver when you need 800W RMS and can't afford the weight of a ferrite motor. The N42 neodymium motor, CMC™ cone, and 3-inch 6-layer Black Coat™ OFC coil are built for sustained power in a motorcycle environment — and the 35 Hz – 1.8 kHz response covers the full mid-bass band. Pair with a FLX1400.4 running bridged channels, or a dedicated FLX1600.1 mono for a dedicated high-power mid-bass channel. For the ferrite-motor version at a lower price point, see the CMB10.S4.
