18 Sound 15NLW9401-4 Woofer

The 18 Sound 15NLW9401-4 is a professional bass driver built around a four-inch voice coil and a neo magnet structure. It is rated for 2400 watts of power handling and presents a four-ohm nominal impedance. This driver targets sound-system engineers and installers who need high-output low-frequency reinforcement in touring or fixed installations.

Suited for high-SPL reinforcement.

The combination of a large voice coil and neo magnet suits applications demanding maximum excursion and thermal capacity in vented or horn-loaded boxes. Builders working with limited cabinet volume or seeking a lightweight mid-bass unit should look at drivers with smaller motor structures and different impedance options.

2400 W power rating with four-ohm load

The 2400 watt rating provides substantial headroom for sustained high-level playback in large venues. Thermal compression remains low during extended duty cycles thanks to the four-inch coil geometry. The four-ohm impedance requires an amplifier capable of delivering rated power into that load; systems wired for higher impedances will not realise the full output potential.

Questions about this item

What amplifier power rating and impedance match does the 15NLW9401-4 woofer require to operate?

The woofer is rated at 2400 W and presents a 4 ohm load, so an amplifier capable of delivering that power into 4 ohms is needed.

Can the 15NLW9401-4 be used alongside older 18 Sound drivers in the same enclosure?

Yes, its 4 ohm impedance and 2400 W rating allow it to share a cabinet with other 18 Sound woofers of the same impedance and similar power handling.

How can I verify the 15NLW9401-4 is performing correctly after installation?

Measure the DC resistance across the terminals; a reading close to 3.2 ohms confirms the 4 ohm voice coil is intact and connected.
