The LAs518A is a high-output active double bass reflex subwoofer engineered to deliver profound low-frequency reproduction down to 24 Hz. Powered by an internal fan-cooled 5000 W 2-channel Class-D amplifier module, it integrates an advanced 96 kHz/40-bit SHARC DSP engine for precise acoustic performance and system protection.

Housed in a rugged, heavily braced 18mm multi-laminate birch plywood enclosure coated in durable polyurea, this unit features dual long-excursion 18-inch drivers capable of reaching 144 dB peak SPL. It supports remote monitoring and multi-device grouping via X-NET PC software over Ethernet, making it suitable for demanding touring and permanent sound reinforcement installations.
