G-Series Speakers

This G-series speaker combines lightweight yet strong materials for reliable performance. Its polypropylene woofer with MICA composite offers improved sensitivity and reduced distortion, while the balanced dome tweeter ensures accurate high-range reproduction for all instruments and vocals.


Mid-Range Dome

The mid-range 30mm PET Balanced Dome produces vibrant high frequencies. Its OFC shorting ring minimizes distortion at higher volumes.
