A professional studio monitor loudspeaker capable of accurately monitoring high-resolution sound sources with a newly developed coaxial driver. A hexagonal form radiating from the unit center directly represents the coaxial driver configuration for reproducing a point sound source. This design fulfils the sound function and at the same time achieves a rigid and flexible majestic appearance. Maintaining the overall balance of the design, a groove is boldly and finely cut for the duct section to radiate sound to the front smoothly to provide a low frequency range with quick response.
