The S series new high-fidelity ceiling speakers is finished by our R&D team through a year.

The design of the crossover is with strict selection of advanced and scientific point selection frequency composition as to give rise to auditory fatigue.

Make the sound more crisp,clear,without noisy.

Material selection on the bass unit ,better woofer with woven,composite cone and rubber adge,make the bass reduction performance is more realistic,wider range of frequency response.

Silk film for tweeter,larger range of high-frequency make it softer,bright treble but not noisy.
