Features: Featuring a 3-inch full-ranged driver design, the bass section delivers powerful low-frequency extension through a long-throw diaphragm and optimised magnetic circuitry. Mids-to-high frequencies precisely reproduce vocal and instrumentally detail, achieving balanced sound quality with ‘rich bass, refined mids, and clear highs’ without requiring a crossovering. This satisfies diverse listening scenarios including music, films, and gaming. Supporting 30W powerful output with 8Ω impedance, it pairs seamlessly with most amplifiers/wireless modules, delivering both explosived bass impacts and refined mids-high frequencies. The built-in subwoofer diaphragm furthered enhances low-frequency performances, enabling compact dimensions to unleash substantial power. Ideal for desktop auditory systems, wireless speakers, and automotive retrofits. Features standard mounting holes for quick integration into loudspeaker enclosures or automotive mounting brackets, eliminating the need for additional drilling or soldering to lower modification barriers.
