The Outline A6S is a compact, high-performance active subwoofer designed for professional live sound, touring, and fixed-install applications where controlled, powerful low-frequency reproduction is required in a small enclosure. Built around a long-excursion 6.5-inch low-frequency driver and driven by a highly efficient onboard Class-D amplifier, the A6S delivers fast, punchy bass with excellent transient response. Its internal DSP ensures precise crossover alignment, driver protection, and phase coherence when paired with Outline full-range loudspeakers, making system integration simple and consistent. The rigid enclosure minimizes resonance and unwanted coloration, allowing the subwoofer to perform reliably in demanding environments such as clubs, corporate venues, studios, and compact performance spaces. Designed for flexibility, the A6S can be deployed as a standalone low-frequency solution or combined in multiples to scale output as needed. Its balanced tonal character makes it suitable for both music and speech-centric applications, providing clean low-end reinforcement without overpowering the mix.
