Overview
The ASTRA 212A 12-inch two-way active line array is specially designed for small to medium-scale sound reinforcement and fixed install applications.
With the innovative ETETM waveguide, the ASTRA 212A achieves even high frequencies diffusion, delivering clear and powerful sound. The horizontal 90 degrees horn provides precise coverage to ensure the system output is uniform, full, and smooth, allowing to the audience an exceptional auditory experience.
The cabinet is made from high-quality CNC processed plywood and with polyuria coating, giving it the characteristics of being waterproof, wear-resistant and heat-resistant as well. The compact symmetrical cabinet structure not only ensures the stability and practicality of the cabinet but also effectively reduces its volume and weight, enabling easier installation and transportation. The ASTRA 212A stands out as an ideal choice for small to medium-scale sound reinforcement applications with its excellent sound quality, stability and flexibility.
