DC Audio XL SPL 10" Subwoofer

The DC Audio XL SPL 10" Subwoofer is a hand-built USA-made 10-inch driver designed for extreme SPL execution, rated at 2200 Watts RMS / 4400 Watts peak, with a typical 7–14 day build time. It belongs to the XL SPL M4 family and reflects DC Audio’s focus on stiff, high-output bass for serious competition-style setups.

• Size and build family: 10-inch driver in the XL SPL/M4 lineage, available in multiple sizes (10, 12, 15, 18) to suit different enclosure and SPL goals.
• Power handling: 2200 Watts RMS / 4400 Watts peak, enabling high-excursion bass with amplified headroom when paired with a suitable amplifier.
• Cone and surround: Extremely rigid non-pressed paper cone with a multilayered polymer foam surround for reduced distortion and controlled cone travel under high power.
• Voice coil: 8-layer flat-wound hi-temp aluminum voice coil for improved heat dissipation and durability during long, deep excursions.
• Motor and frame: FEA-analzyed and optimized motor assembly with a fully CNC-machined cast aluminum frame and a rubber motor boot for stiffness and clean motion.
• Mounting and hardware: 8" OD stiff semi-cupped spiders, chrome spring-loaded push terminals, and a rubber mounting gasket for solid installation and reliable electrical connections.
• Impedance options: Ohm options in dual configurations (.7/1/1.4/2/4) to match a range of amplifier impedances and system layouts.
• Performance data (10" specific): Sd 324 cm², Vas 12.42 L, Cms 0.085 mm/N, Mms ~171.8 g, Fs ~41.7 Hz, Re 3.98 Ohm, Le ~5.2 mH, Qts ~0.34, Xmax 26 mm, Ref SPL @1W ~85.9 dB; sealed box ~0.75 ft³; ported box ~1.0 ft³.

Benefits: This 10" driver is tuned for high-SPL builds where amplifier power, enclosure design, and a stiff motor system must work in harmony. Its 0.75 ft³ sealed or 1.0 ft³ ported enclosure guidance, combined with an aggressive motor and low Distortion motor design, makes it suitable for competition-level bass in a variety of cars. The dual-impedance options provide flexibility to match amps and wiring strategies, while the USA-built, hand-assembled construction emphasizes reliability in demanding installations.
