15" Neo Driver for Pro Audio

The 18 Sound 15NTLW3500-4 is a fifteen-inch neodymium low-frequency transducer built for professional sound reinforcement. Its three-and-a-half-inch voice coil handles high continuous power in touring cabinets and fixed installations. The unit is manufactured in the United States and ships new.

900 W RMS Continuous Power Rating

The single specification that defines suitability is the 900 W RMS power handling. System designers must match amplifier output and cabinet tuning to this thermal limit to avoid coil damage. No other impedance or sensitivity figures are supplied for crossover alignment.

Thermal Behaviour Under Load

The neodymium motor structure and large voice coil dissipate heat during extended high-output use. Power compression remains controlled when the driver operates within its rated continuous power. No fan noise or active cooling is present in this passive component.

Questions about this item

How does the 900 W RMS rating translate to real-world headroom in a 15-inch cabinet?

The 900 W RMS figure means the driver can handle continuous power at that level without thermal damage, giving ample headroom for high-SPL bass reinforcement in a properly tuned enclosure.

What impedance does the 4-ohm voice coil present to the amplifier?

The 4-ohm nominal impedance matches amplifiers rated for 4-ohm loads, allowing full power delivery without triggering protection circuits on most professional power amps.

What front-panel cut-out diameter does the 15-inch frame require?

The 15-inch frame needs a standard 15-inch driver cut-out, typically around 350 mm, with bolt-circle spacing that matches common 15-inch bass cabinet layouts.
