1. Cabinet is made of high quality plywood with the groove splicing process, which make the structure more durable, reduce dyeing, advance design makes the low frequency strong and pure.

2. The 1.75" treble driver diaphragm assembly is imported from Europe, the 10 inch woofer also uses the materials which imported from Europe. .The speaker is with ultra-high sound pressure level and clear, translucent medium and high frequency. It's the best choice no matter singing or doing high-end business meeting.

3.Crossover uses the original U.S. imported  ERSE capacitance and super cooling aluminum shell resistance, they are used with aluminum radiator, maximized the efficiency and reduce the unnecessary distortion.

4. After many times careful simulations and optimized design experiments, the tweeter uses BOST patent protection circuit, ensure that no frequency drift occurs during high power operation work condition. The treble and bass are perfectly connected, the low frequency is thick and powerful, the medium frequency is bright and transparent, the voice is round and gorgeous, and it is easy to enter the microphone.
