AS18SUB - 18" Active Subwoofer - 800W RMS Class-D Amplifier - Adjustable Crossover & Polarity Control

The Offshore AS18SUB is a high-performance active subwoofer designed to deliver powerful, deep low-frequency reinforcement for live sound, DJs, mobile entertainers, venues and installed audio systems.

Equipped with an 18-inch woofer driven by an efficient 800W RMS Class-D amplifier, the AS18SUB produces impressive bass response down to 30Hz with a maximum SPL of 124dB, providing the low-end impact required for demanding sound reinforcement applications.

The integrated active crossover offers selectable high-pass frequencies of 80Hz, 100Hz or 150Hz, allowing seamless integration with full-range loudspeakers, while the polarity switch ensures optimal phase alignment within any system.

Balanced XLR inputs, parallel full-range outputs and filtered high-pass outputs provide flexible connectivity and system expansion options. 

Built into a robust MDF enclosure with a 35mm pole-mount socket, the AS18SUB is equally suited to portable and fixed-installation applications.
