Outline Movie S218 Cinema Subwoofer: 2 x 18”

Purpose-built for modern multiplexes and boutique screening rooms alike, the Movie S218 unleashes the engulfing low-frequency energy audiences expect. Leveraging the same premium components found in Outline’s world-touring sound systems, this compact yet formidable cabinet pairs two long-excursion 18″ woofers with a precision-tuned vented design to reproduce every explosion, engine roar and musical crescendo with cinematic authority.
Deep Low-Frequency Performance

With usable response down to 25 Hz and a staggering 139 dB short-term SPL, the Movie S218 effortlessly fills any auditorium with tactile bass. Its high-power 18″ drivers feature oversized voice coils and extended linear travel, delivering clean, distortion-free output even at reference playback levels.
Touring Heritage in Cinema

Borrowing directly from Outline’s flagship live-sound enclosures, the cabinet employs premium birch plywood, robust internal bracing and touring-grade hardware. The result is uncompromising reliability, day after day, show after show.

The sub is optimized for use with the Outline iP 24 system processor via AES3 inputs, ensuring rapid setup and consistent tonal balance across multi-channel arrays. Secure screw-type terminals and a manageable 85 kg weight streamline permanent installation behind screens or beneath stages.
