12-Inch Powered Subwoofer for Home Audio

The ELAC PS350-BK is a powered subwoofer built around a custom 12-inch driver with a 2-inch voice coil. It delivers 350 watts RMS and 700 watts peak from a BASH amplifier. The unit suits stereo or home-theatre systems that need deep bass extension down to 21 Hz. Its 108 dB sensitivity ensures high output with minimal amplifier strain.

Flexible Connectivity and App-Based Setup

The cabinet provides RCA line-level and speaker-level inputs for integration with almost any amplifier or receiver. A USB port supports the companion app, which handles AutoEQ calibration for flexible room placement. The 40 Hz to 150 Hz low-pass crossover is adjustable via the app. No wireless streaming or HDMI connections are included.

Sealed MDF Cabinet with Bass-Reflex Port

The 30 mm thick MDF enclosure uses internal cross-bracing and acoustic damping to control resonance. A bass-reflex port extends low-frequency response while the high-excursion surround manages cone movement. The 28-bit DSP governs amplifier behaviour and protection circuits. The package includes a grille, power cord and floor spikes for stability.
