    Description

    The Martin Audio Blackline X115 is a compact, direct-radiator passive subwoofer engineered to extend low-frequency performance in portable and installed sound systems, particularly when paired with Blackline X Series full-range loudspeakers. It utilises a long-excursion 15-inch driver with a 3-inch voice coil housed in a bass reflex enclosure, delivering controlled, musical bass from a space-efficient cabinet.

    Constructed from durable plywood and finished in black textured paint, the enclosure is designed for professional use and protected by an impact-resistant perforated steel grille. Four large front ports minimise air noise at high output levels, ensuring clean and consistent low-frequency reproduction. The cabinet includes a 35mm pole-mount socket for satellite speaker mounting, two ergonomic side handles for easy handling, and rubber feet that resist movement while aligning with top-surface recesses for stable stacking.

    Deployment options include single use, stacked configurations or flown installation via integral M10 flying inserts, making the X115 suitable for a wide range of applications from mobile PA to fixed installations. With an 8 ohm nominal impedance and robust construction, the X115 provides a reliable and compact low-frequency solution for professional environments from Martin Audio.
