DS18 IXS10.4S IXS Shallow 10" Subwoofer 1200 Watts SVC 4-Ohm

The DS18 IXS10.4S is a shallow-mount 10-inch subwoofer delivering 600W RMS (1200W MAX) for deep, precise bass in tight automotive spaces. Built on DS18's slim SW lineage, it pairs a compact footprint with robust power handling—designed for enthusiasts who want big bass in limited-depth installs.

• Nominal Diameter / Impedance: 10" (254 mm) diameter with 4-ohm impedance. In real-world use, a 4-ohm load is compatible with a wide range of amplifiers and supports solid, controllable bass performance.
• RMS / MAX Power Handling: 600W RMS / 1200W MAX. Real-world: ensures continuous bass authority with headroom for dynamic peaks when paired with an appropriate amplifier.
• Sensitivity: 84 dB (1W/1m). Real-world: higher efficiency means you can achieve louder output with less amplifier power compared to lower-sensitivity designs.
• Frequency Response: 20–800 Hz. Real-world: covers deep sub-bass up to upper-bass frequencies, aiding seamless blending with midbass and front-stage frequencies.
• Shallow Mount & Dimensions: Mounting depth 3.66" (93 mm); overall depth 4.48" (114 mm); cutout 9.25" (235 mm); displacement 0.9 L. Real-world: compact depth enables installation in limited spaces while displacement contributes to bass output for its size.
• Recommended Enclosures: Sealed internal volume minimum 14.2 L (0.5 ft³); F3 44 Hz. Real-world: in a sealed box, this yields tight, controlled bass down to about 44 Hz with predictable response.
• Voice Coil & Construction: 2.5" (63.5 mm) aluminum voice coil; single voice coil (SVC); copper winding. Real-world: robust coil and aluminum former support power handling and heat dissipation for sustained bass.
• Materials & Build: Cone Paper; Dust Cap Fiberglass; Surround Stitched Rubber; Basket Aluminum; Magnet Ferrite. Real-world: lightweight, rigid construction aids accurate bass and durability in car environments.
• Physical Dimensions: Overall diameter 10.63" (270 mm); Cutout 9.25" (235 mm); Mounting depth 3.66" (93 mm); Weight 62 oz (driver only). Real-world: precise fitment guidance helps planning in limited-trunk or under-seat spaces.
• Thiele–Small Parameters: Vas 20 L; Fs 38 Hz; Qts 0.602; Mms 145.6; Re 3.6 Ω. Real-world: these values support enclosure modeling and predict performance in sealed installations.

In a car audio build, the IXS10.4S excels in sealed, compact enclosures where space is at a premium. Its 4-ohm voice-coil and 600W RMS continuous rating pair with a suitable amplifier to deliver controlled bass with headroom, while the shallow depth and 14.2 L minimum enclosure keep mounting options flexible. The wide 20–800 Hz range and 44 Hz F3 in sealed boxes provide bass that remains tight and musical even when space constraints are tight.
