1. The chamber is made of high quality plywood with into the slot is woven process, make the structure more durable, reduce dyeing.

2. The high of 1.*5 was used to realize the "European imported diaphragm components, *2" bass unit adopting Malaysia space magnetic design and combination of imported materials. With super sound pressure level and clear and transparent in high frequency, whether singing or doing high-end business meeting amplification of a class is the best choice.

3. The crossover network USES the aluminum shell resistance of polypropylene capacitors and super cooling, cooperate with the aluminum radiator, maximize the efficiency and reduce the unnecessary distortion.

4. After a lot of experiments on simulation and optimization design meticulously, high-pitched adopted BOST company patent protection circuit, ensure do not produce frequency drift when he worked in high power, high and low sounds perfect cohesion, low-frequency vigorous powerful, flexible, intermediate frequency bright transparent, voices and luxuriant, easily into the microphones.

Application Range: Return to the stage, conference rooms, lecture hall, multi-function hall, auditorium, school, etc
