DS18 IXS12.4S
The IXS12.4S is a high-performance 12-inch shallow-mount car subwoofer designed to deliver deep, powerful bass even in tight installation spaces without requiring a deep enclosure. Featuring a single 4 Ω voice coil (SVC) with a 2.5″ aluminum voice coil former and a 62 oz ferrite magnet, it handles 800 W RMS and up to 1600 W peak power for robust low-end output. With a wide frequency response from approximately 20 Hz to 600 Hz and 85 dB sensitivity, the IXS12.4S produces rich, controlled bass suitable for sealed or ported enclosures. Its paper cone, fiberglass dust cap, stitched rubber surround, and aluminum basket ensure durability and efficient performance, while the shallow ~4.33″ (110 mm) mounting depth lets it fit snugly into compact boxes or under-seat locations in cars, trucks, marine, or powersports audio systems.
