The Atlantis Lab AT31 PRO is the flagship high-power loudspeaker in the Atlantis Lab range, engineered for large listening rooms and systems where maximum dynamics, efficiency, and musical impact are required. Utilizing a true 3-way design, the AT31 PRO combines a horn-loaded neodymium compression driver, dedicated midrange driver, and large dual-woofer configuration to deliver exceptional scale, detail, and authority across the entire frequency range.
With an impressive sensitivity of 101 dB and power handling capability of up to 800 watts, the AT31 PRO is designed to perform effortlessly with both low-powered tube amplifiers and high-output solid-state systems. The combination of large-format Eighteen Sound drivers and horn-loaded high frequencies allows the speaker to reproduce subtle musical nuances alongside explosive dynamic contrasts with equal confidence.
The speaker’s bass system combines a substantial 310 mm neodymium woofer with a supplementary rear-mounted 260 mm woofer, producing deep, controlled low frequencies while maintaining speed and articulation. Adjustable bass reflex tuning, premium internal wiring, pure copper terminals, and custom-designed spikes further reinforce the AT31 PRO’s position as a reference-level loudspeaker for demanding audiophile installations.
