DC Audio Shortie FTW 10" Subwoofer

DC Audio Shortie FTW 10" Subwoofer is a compact 10-inch woofer designed for tight-depth installations, delivering controlled bass with a 2.5" voice coil and a FEA-optimized motor assembly for reliable 500W RMS/1000W peak power handling in sealed or ported enclosures.

• 2.5" voice coil: A larger excursion motor is better at handling heat and maintaining control during hard bass peaks, improving precision under high-power playback.
• Power Handling (RMS/Peak): 500W RMS / 1000W peak. This specifies the continuous power the driver can comfortably handle and the peak it can sustain for brief transients without bottoming out.
• Mounting Depth: 5". Designed for tight installations where depth is limited, enabling deeper bass in smaller enclosures or trunk spaces.
• Outside Driver Diameter: 11". Indicates the overall footprint needed in the mounting cutout and enclosure to ensure proper fit and airflow.
• VC Diameter: 2.5". Consistent with the voice coil size, affecting heat dissipation and dynamic response at high excursion.
• Displacement:.11 ft³. Represents the air moved by the cone, influencing low-frequency output in a given enclosure.
• Sd (Total cone area): 346 cm². Larger cone area supports more air movement for deeper bass in the same enclosure size.
• Vas (Equivalent compliance): 7.17 L. Helps determine the enclosure volume needed for tuned performance and box alignment.
• Cms (Lumped compliance): 121.51 μm/N. Indicates how much the cone would compress under a given force, impacting motion and control.
• Mms (Suspension mass): 218.5 g. Affects the driver’s natural resonant behavior and transient response.
• Fs (Free-air resonance): 45.5 Hz. Sets the low-end emphasis and helps dictate suitable enclosure tuning for bass extension.
• Re (DC resistance): 7 Ω. Important for amplifier damping and impedance compatibility in system design.
• Xmax: 14 mm. Maximum linear excursion, defining how far the cone can travel before distortion limits begin to occur.
• Ref SPL @ 1W: 82 dB. Baseline sensitivity, indicating the SPL produced with one watt of input in free air.
• Enclosure recommendations: Sealed Box 0.5 ft³; Ported Box 1.0 ft³. Practical guidelines for box sizing to achieve expected bass performance with this driver.
• Ohm options: d2/d4. Indicates available impedance versions (2 Ω or 4 Ω) to suit different amplifier/topology choices.
• Construction highlights: Stitched surround and paper cone, Rubber motor boot with DC logo, Polypropylene dust cover with DC logo, Heavy-duty interweaved tinsel lead wire sewn to the spider, Cast aluminum black frame, FEA-analyzed motor assembly with CNC-machined side venting, Rubber mounting gasket, Chrome spring-loaded push terminals, Side motor venting, Chrome top plate and T-yoke.

Benefits: This Shortie is tailored for installations with restricted mounting depth while delivering solid bass through both sealed and ported enclosures. The 2.5" voice coil and 14 mm Xmax support controlled travel and power handling, making it suitable for compact builds that still demand impactful low-end performance. The impedance options and enclosure guidance help integration with a variety of amplifiers and box sizes, while the robust construction and venting features promote durability and consistent performance in real-world automotive setups.
