Adam Audio SUB 2100

The Bass Titan in the ADAM Audio Range

Designed for large control rooms and demanding mixing consoles, the Sub2100 establishes itself as a bass reference at ADAM Audio. Its massive 21.5-inch woofer and 6-inch voice coil-the largest ever developed by the brand-allow it to reach spectacular sound pressure levels while maintaining an extended and controlled response down to 18 Hz. It thus sets a new benchmark for professional applications where low-frequency accuracy is essential.

Who Is It For and What Are Its Uses?

The Sub2100 is aimed at cinema post-production studios, music and broadcast mixing rooms, as well as immersive environments requiring massive level peaks without compromising clarity. It complements high-end monitoring systems by providing foundation, impact, and precision, whether for sound design, bass phase control, or translation verification on high-level systems.

Key Technologies for Ultra-Controlled Bass

At the heart of the Sub2100, the enormous 6-inch voice coil ensures exceptional power handling and linear excursion that minimizes mechanical compression at high levels. Combined with a low-tuned Bass Reflex enclosure, the driver easily reaches down to 18 Hz while maintaining a THD below 1% above 60 Hz. The 1000 W continuous amplification provides the necessary headroom to handle transients without collapsing, even in large volumes.

For integration, the cutoff frequency adjustment from 50 to 150 Hz simplifies matching with your main speakers. Symmetrical XLR and asymmetrical RCA inputs guarantee reliable connection to most interfaces and monitoring controllers, while the 99 dB/W/m efficiency ensures remarkable daily performance.
