Features

This series of speakers is a multi-frequency 4.5-inch full-range unit and a 25-core composite membrane tweeter, the surface of the surface of the spraying of fine point paint process composed of compact two-way speaker, full-range speakers with a professional tweeter, the overall penetration is stronger, the sound performance is more real.

Full-frequency unit is a 25mm diameter high-power voice coil, voice coil skeleton using high strength aluminium materials, not only to strengthen the strength of the voice coil to increase the power of the voice coil to withstand the ability. The symmetrical magnetic circuit of the unit is designed so that the odd harmonic distortion of the low-frequency part is reduced to a low degree, which fully satisfies the human ear's demand for sound quality.
