HELVIA ONDA B520W | 5.25" 2-Way Coaxial Ceiling Speaker, 20W RMS, 70/100V, with Enclosure, White
The ONDA BW series includes high-performance coaxial ceiling speakers, designed for professional installations requiring clear, balanced, and dynamic sound. They are compatible with both 70/100V line amplifiers and low-impedance 8 Ohm amplifiers, offering flexibility in system design and installation.
Enhanced Acoustic Performance
The integrated rear enclosure (back can) with a front-facing bass reflex port enhances mid-low frequency response, delivering a warmer and fuller sound. This ensures high-quality performance even when the false ceiling does not function as a natural speaker enclosure, unlike conventional ceiling speakers.
