Coaxial treble provides original audio reproduction?

Two speakers are installed on one axis, one of which reproduce treble and the other mid bass. One speaker functions as two. The

overlapped speakers make the physical position near point acoustic source, so the reproduced music sound field position is better,

which features high phase position quality of reproduction and effectively solves the influence of the phase deviation of the

separated speaker on the correct reproduction of the acoustic image.

Treble

and

Bass

 

Extraordinary sound quality

home becomes theatre?

Mid bass basin uses Kevlar drum paper full tone vibration

film, which better reproduce mid-range, real and powerful

bass, bigger power density, good and flexible transient.

Coaxial treble, the tweeter uses 24-line batiste silk, which

guarantees exquisite treble. It provides extraordinary

sound quality that you can enjoy the cinema feeling at

home.

Small size, beautiful and exquisite?

4-inch exquisite design with pure white appearance, which is plain pure

and fashionable.

 

Magnetic suction type rimless mesh, dustproof and safe?

Dustproof mesh can reduce the dust adsorption, which protects the pure sound quality and prolong the service life.

The magnetic design makes the installation very easy. The magnetic is very strong, so there’s no need to worry about

the vibration and the drop. The rimless design is very pure; the appearance is simple, no easy to fade or deformed.
