The Atlantis Lab SUB AT54 PRO is the ultimate subwoofer in the Atlantis Lab range, engineered for listeners and installations that demand extreme low-frequency performance with uncompromising control. Built around a massive 540 mm Eighteen Sound woofer and a large 250-litre enclosure, the SUB AT54 PRO is designed to reproduce the deepest bass frequencies with authority, precision, and scale.

With extension down to 20 Hz and an enormous 5000 W power handling capability, the SUB AT54 PRO is capable of delivering subsonic information that remains beyond the reach of many conventional subwoofers. Its design focuses not only on output but also on maintaining control and articulation throughout the bass range, making it suitable for both high-end music reproduction and demanding large-room installations.

The enclosure volume can be adjusted on request to optimise performance for specific listening environments. Combined with premium Esprit Audio internal wiring, high-quality construction, and compatibility with Atlantis Lab reference loudspeakers such as the AT31 PRO and AT38 PRO, the SUB AT54 PRO delivers a level of bass performance intended for truly no-compromise systems.
