Experience deep, controlled bass in even the tightest spaces with the DS18 SQBASSX2, a compact powerhouse engineered to redefine your in-car sound experience. Designed for enthusiasts who want thunderous low-end response without sacrificing cabin space, this innovative system integrates a 7x9” amplified subwoofer and a 4x6” passive radiator, delivering exceptional bass clarity, warmth, and impact.

With a 230W RMS / 1200W Peak power output, the SQBASSX2 produces remarkable low-frequency extension and precision that rivals much larger enclosures. Its frequency range of 34Hz–400Hz ensures every bass note—from smooth, rounded lows to tight, percussive thumps—is rendered with lifelike accuracy. Despite its sleek, under-seat form factor, the SQBASSX2 packs the full authority of a premium subwoofer system into a body that easily fits under most standard car seats or compartments.

The digital Class D amplifier inside the SQBASSX2 ensures efficient power management and minimal distortion, while a remote control knob (with 16ft cable) allows you to fine-tune your bass output between 0–30dB directly from your dashboard. With a low pass crossover adjustable between 50Hz and 150Hz, seamless integration with your existing speakers is effortless. The auto signal-sensing power-on feature simplifies installation and ensures your sub is always ready when the music starts.

Built for durability, the SQBASSX2 features a steel basket, polypropylene cone, and rubber surround housed in a robust aluminum chassis for superior heat dissipation and vibration resistance. Safety and reliability come standard with full circuit protection, including thermal, overload, DC, short circuit, and voltage safeguards.

Compact, intelligent, and powerful—the DS18 SQBASSX2 is proof that great things come in small packages. Add this to your setup and feel the music come alive with rich, dynamic bass that fills your vehicle from the floor up.
