More output, more authority, more thermal control — the Level 4 (M4) is DC Audio's step up for serious bass.

This is the DC Audio Level 4 (M4) subwoofer, the next step up for anyone who wants more output, more authority, and more thermal control than the Level 3. If the Level 3 is the everyday street sub, the Level 4 is what you run when you want to push harder and hold up to it. Hand-built in the USA and rated at 1500W RMS, this is a real high-output sub built to slam and keep slamming.

Available in 10", 12", 15", and 18" to match your space and your goals, with impedance options to dial in your amp and wiring — plus your choice of dust cap logo color to set it off. Whether you're building a loud daily or a dedicated bass setup, the Level 4 brings the output and the durability to back it up.
