Martin Audio SXP218 Dual-Driver Powered Subwoofer

The Martin Audio SXP218 is a dual-driver powered subwoofer designed for touring, theatre, and live sound applications. Featuring two 18-inch drivers and a 4000W Class D amplifier, it delivers high output with Dante digital audio networking. Procure.ae supplies this professional audio equipment to businesses across the UAE.

The SXP218 utilizes two 18-inch long-excursion drivers with 100mm voice coils and ferrite magnets to achieve a frequency response of 35Hz-150Hz ±3dB. It produces 143dB peak SPL at one metre, driven by a 4000W Class D amplifier with onboard DSP and VU-Net software. The multi-laminate birch plywood enclosure features a polyurea coating and black perforated Zintec grille.

Networking is handled via Dante Digital Audio using Ethercon connectors, while audio inputs/outputs use XLRs. It accepts 85-265V AC at 50-60Hz through a Neutrik Powercon True1 input, consuming 550W nominally. The unit supports omnidirectional or cardioid dispersion with CDD Live crossover presets and includes M8 inserts and M10 mounting points for installation.
