Product Introduction
Professional Audio System – Dual 10‑inch Professional Line Array System (OBT‑BLA210 / OBT‑BLA208S)
OBT‑BLA210 Dual 10‑inch Passive Binaural Frequency Division Line Array System
The OBT‑BLA210 features high‑strength long‑stroke dual 10‑inch low‑frequency units, dual neodymium magnet tweeters, and an external active frequency division design. It is specifically tailored for line array applications, with powerful bass impact and extremely strong mid‑high frequency penetration. It always brings people a sense of surging energy.
The OBT‑BLA210 passive line array achieves distortion‑free wavefront propagation and has excellent directivity. It is suitable for long‑distance sound reinforcement. Its sound field is uniform, with little sound interference, which helps improve the fidelity of the sound source. It has extremely strong vertical directivity, a narrow radiation beam, precise direct sound intensity coverage of the target audience area, a long projection distance, and a small change in large‑area sound pressure level.
Application scenarios:
The OBT‑BLA210 passive line array can be used all year round outdoors, supporting mobile or fixed installation. It can be stacked or hung. Its application range is wide, such as: touring performances, concerts, bars, opera houses, stadiums, etc. Its outstanding effect brings more possibilities to your music experience.
