This series of professional column speakers for conference applications features a racetrack driver design. Each unit includes a 50×90mm racetrack-shaped (equivalent to 2.5") paper cone woofer and a 1" tweeter, delivering high sensitivity and low distortion. The sound is natural and pleasant, with a soft, well-balanced tonal character. A specially engineered linear acoustic structure enhances mid-to-high frequency reproduction, offering better directivity than conventional speakers — resulting in more focused sound energy and improved clarity and balance throughout the listening area.

A switchable 100V constant voltage / 8Ω constant resistance mode allows flexible adjustment to suit different system configurations and installation needs.

Each speaker is housed in a high-quality aluminum alloy enclosure with a sealed design that improves durability and reduces unwanted resonance. The streamlined metal grille fits flush with the cabinet, providing a sleek, modern look.

These speakers are ideal for small to medium-sized venues, including restaurants, tea houses, train stations, schools, plazas, office buildings, meeting rooms, home theaters, churches, and more.
