The DS18 IXS12.4S is a 12‑inch shallow-mount car subwoofer designed for high-performance audio systems where space is limited. Delivering up to 1,600 W peak (800 W RMS) with a single 4 Ω voice coil, it provides deep, powerful bass without requiring a deep enclosure. Its compact design, robust construction, and high-quality materials make it ideal for competitive SPL setups or premium car audio installations, ensuring impressive low-frequency performance even in tight spaces.

Key Benefits

• High power handling: 800 W RMS and 1,600 W peak deliver strong, deep bass.
• Shallow-mount design: only 4.73″ mounting depth allows installation in small enclosures or under seats.
• Efficient performance: 85.1 dB sensitivity converts amplifier power into impactful sound.
• Wide frequency response: 20 Hz – 600 Hz for rich low-frequency reproduction.
• Durable construction: reinforced paper cone with stitched rubber surround and fiberglass dust cap.
• Large ferrite magnet (62 oz) for controlled excursion and stable operation.
• Heavy-duty aluminum basket ensures rigidity while minimizing resonance.
• Supports sealed enclosures with minimal recommended volume (~28 L).
• Suitable for SPL and high-output car audio systems.

Installation & Compatibility

The IXS12.4S is ideal for vehicles with limited installation space, such as under-seat enclosures or shallow trunks. It works best in sealed boxes of approximately 28 L (~1 ft³) for tight bass control. Pairing with an amplifier capable of 600–900 W RMS at 4 Ω will provide optimal performance while maintaining reliability. Its shallow depth ensures flexibility in custom or constrained installations without sacrificing low-frequency impact.
