The Axi-Sub is a self-powered, high-output subwoofer suitable for both flown and ground stacked configurations. This compact subwoofer integrates smartly with the Apia Axi self-powered, full-range loudspeakers. The integrated standard 35mm pole-mount receptacle, included with all Axi-Sub, allows the subwoofer to be easily paired with Axi series loudspeakers for either fixed or touring applications. The Axi-Sub subwoofer boasts an operating frequency range of 29 Hz to 60, 80 or 100 Hz and a peak SPL of 136 dB at 1 meter. The 18-inch cone driver with neodymium magnet is engineered to deliver optimal subwoofer performance. The Axi-Sub features an on-board DSP with a preloaded presets library, providing intuitive control over the main functions with buttons and display. All DSP functions, including gain, mute, delay, preset recall and store, can also be remotely controlled via software over RS485. The high-excursion back-vented driver is rated to handle 1100 W / 4400 W RMS peak, which is housed in a tuned enclosure constructed of Baltic birch plywood. The durable Apia Axi-Sub enclosure is coated with Polyurea finish.
