FAQ Section

1. What are the advantages of using a neodymium magnet in an 18-inch professional subwoofer?

Neodymium magnets provide an exceptionally strong magnetic field relative to their size, allowing the speaker to deliver massive acoustic force with a drastically reduced physical profile. 

2. How much power can the Audiotone AD-18NW128 handle safely during a live event?

The Audiotone AD-18NW128 is designed for rigorous live sound environments, safely managing a continuous 2200W RMS of nominal power. It features an impressive peak threshold of 4400W continuous maximum power.

3.Why does an in/out wound voice coil layout improve speaker reliability?

An inside/outside wound voice coil features copper wiring wrapped on both the inner and outer surfaces of the coil former. This dual-layer structure doubles the exposed surface area, allowing the assembly to dissipate intense thermal energy.

4. How heavy is the Audiotone AD-18NW128 subwoofer, and is it practical for mobile DJ setups?

Weighing exactly 14.6 kg, the Audiotone AD-18NW128 is engineered to be one of the lightest high-power 18-inch subwoofers available in its performance class. Combining an N45 neodymium motor structure with a rugged.

5. What frequency range should an 18-inch subwoofer cover for full-range PA system support?

For proper low-frequency support, an 18-inch subwoofer should smoothly cover a wide range from sub-bass depths up into the low-mid frequencies, typically between 43Hz and 2300Hz.
