DC Audio M4 Level 2 10" Subwoofer

The DC Audio M4 Level 2 10" Subwoofer is a high-excursion 10" driver built for enthusiasts who demand real-world bass in sealed or ported enclosures. For 2025 it’s redesigned to deliver 33% more output than the previous Level 2, featuring a double-stacked FEA-optimized motor, chrome top plate and T yoke, and 22 mm of X-Max for sustained high excursion. Designed in the USA by American Audio Engineers and rated at 750W RMS / 1500W peak.

• Double-stacked FEA optimized motor: A dual-stack magnetic system engineered via finite element analysis to improve stiffness and control under high drive.
• 22 mm X-Max: Maximum voice-coil travel, enabling strong bass output within the 10" form factor.
• 2.75" Hi-temp copper voice coil: Large-diameter coil for high power handling and thermal resilience.
• Cast aluminum black frame / no invert mount: Rigid, durable construction that maintains alignment during heavy excursions.
• Extremely rigid non-pressed paper cone assembly: Stiff cone helps preserve timing and accuracy under load.
• Stitched Multilayered polymer surround: Durable surround that supports long-term reliability with consistent excursion.
• 8" OD Progressive High Output spiders: Provides controlled suspension for linear motion at high excursion.
• Heavy duty flat tinsel lead wire sewn to the spider: Robust electrical connection through large movements.
• Rubber mounting gasket: Seals and isolates vibrations at the mounting surface.
• Chrome spring loaded push terminals: Secure, easy-to-use connections for consistent contact under load.
• FEA analyzed and optimized motor assembly - Fully CNC machined: Precision-machined components with tight tolerances for repeatable performance.
• Power handling: 750W RMS / 1500W peak for ample headroom with dynamic music.
• Enclosure compatibility: Performs in sealed or ported enclosures as part of its design.
• Mounting and sizing: 6.0" mounting depth, 9.35" mounting hole diameter, 11.0" outside diameter, 2.75" VC diameter, 0.13 ft³ displacement.
