SUBLINE 115SA Overview

The FBT SUBLINE 115SA is an active subwoofer engineered for installations and portable deployments where deep, controlled bass reproduction is required. At its core is a 15″ high-excursion woofer with a 3″ voice coil, powered by a 700W Class D amplifier that delivers precise, punchy low-end performance. The enclosure is constructed from durable birch plywood with a scratch-resistant finish, built to withstand the demands of professional use. This unit is well-suited for system integrators, touring companies, houses of worship, and venue installations requiring reliable subwoofer reinforcement.

Ergonomic handles facilitate transport and positioning, while an integrated M20 top mount enables straightforward pole-mounting configurations for flexible system deployment.
