NVX SMW10D4 700W Peak Shallow-Mount 10-inch Dual 4-Ohm Subwoofer

Overview

The NVX SMW10D4 is a compact, high-output subwoofer designed to deliver deep, controlled bass without taking up valuable space. With a peak power handling of 700 watts and an RMS rating of 350 watts, this dual 4-ohm driver is built to bring lower frequencies to life in a wide range of systems.

Key design advantages

At the heart of the SMW10D4 is a carbon fiber reinforced polypropylene cone. This combination provides stiffness and durability, helping to maintain accurate bass response even at higher output. The cone’s rigidity helps minimize distortion as the music intensifies, allowing for tighter, more defined low end.

• High-Performance 10-inch shallow-mount design for deeper bass in compact spaces.
• Dual 4-ohm voice coils offer flexible wiring options and impedance matching with existing amps.
• Butyl rubber surround enhances excursion capability and longevity under heavy bass passages.
• 50-ounce ferrite magnet provides consistent, powerful magnetic field for controlled dynamics.
• Top-mount depth of 3.23 inches, with a depth extension plate included to maximize space for shallow boxes.

Sound and durability in real-world setups

Designed to work with a variety of systems—from sealed enclosures to compact ported boxes—the SMW10D4 can help you achieve a robust bass presence without overwhelming midrange clarity. The carbon fiber cone and sturdy surround help resist fatigue during long listening sessions, delivering reliable performance across a range of genres.

Whether you’re upgrading a factory setup, building a custom install in a small vehicle, or replacing an aging sub, this model emphasizes controlled low-end response and crisp transients. While performance will depend on enclosure and amplifier pairing, the design focuses on preserving detail at high output and ensuring consistent behavior under bass-heavy passages.

Installation and compatibility notes

The 3.23-inch mounting depth makes installation easier in tight spaces, and the included depth extension clearance plate adds extra room when needed. The dual 4-ohm voice coils provide wiring flexibility for multiple amplifier configurations, helping you tailor the system for your preferred power levels and impedance.

• Easy fit in compact enclosures thanks to shallow-mount design and optional depth extension plate.
• Flexible wiring options with dual 4-ohm voice coils for various amp setups.
