Equipped with a 1.3-inch copper voice coil and rated for 200 watts of continuous power, the B&C 4NDS34 offers exceptional thermal stability and headroom for its size. Operating linearly from 60 to 800 Hz, it maintains controlled excursion and tonal consistency even under demanding conditions. At Comma, we use four units per enclosure to achieve not only acoustic coupling and energy distribution, but also to reduce individual stress, keeping each driver in its optimal working range. As with all B&C components, quality control is among the most stringent in the industry — ensuring reliability, unit-to-unit consistency, and long-term precision.
