Description
The Pioneer TS-WX400DA is a compact, space-saving powered subwoofer engineered to deliver strong low-frequency impact without occupying cabin or boot space. Built around a high-efficiency Class-D amplifier and a down-firing driver orientation, it utilizes integrated DSP tuning to give you full control over your vehicle’s sound signature.
Key Features & Overview
- Built-in Class-D Amplifier: Delivers an efficient 100W RMS power output (250W Max) with low power consumption (9.4A max current draw) and minimal thermal loading.
- Down-Firing Enclosure Design: Fires sound downward against the vehicle floor, leveraging cabin acoustic loading to maximize bass impact while protecting the woofer cone from dirt, shoes, or cargo.
- Digital Bass Control (DSP): Integrated digital sound processing provides two distinct, selectable EQ modes via the included remote:
- DEEP Mode: Focused on ultra-low frequency reproduction (20 Hz to 100 Hz), ideal for jazz, classical, country, and acoustic tracks.
- DYNAMIC Mode: Boosts output performance for punchier, body-rocking low end tuned for EDM, hip-hop, and rock.
- Wired Remote Controller: Adjust gain levels, switch between DSP bass modes, adjust the variable low-pass crossover (50 Hz – 125 Hz), and toggle phase control (0°/180°) straight from the driver’s seat.
- Low Power & Flexible Wiring: Efficient current draw allows for straightforward wiring solutions, compatible with both aftermarket RCA outputs and factory (OEM) high-level speaker inputs.
