1. box of high quality plywood combined into the slot wedge bonding process, so that the cabinet structure is more durable. Before adopting the low-frequency inverter design allows clean and powerful.

2. treble driver uses 1.75 "diaphragm assembly imported from Europe, the horn can use multi-angle rotation, bass 10" uses the same materials made European imports. With superior sound pressure level and clear translucent high-frequency, either singing or doing high-end business meeting class PA are the best option.

3. rapid expansion of the treble horn adjust the time difference between the high and low frequency unit and calibration phase angle difference and ensure a smooth wavefront provide precise beam pattern control while carefully designed to eliminate interference crossover point in the nearby area.

4. crossover network imported from Germany, HI-CAP golden high quality capacitors and air-core inductors round, Treble BOST patent protection circuit design, superior heat resistance of aluminum with aluminum radiator used together to maximize the efficiency and reducing unnecessary distortion.

5. Through many years of senior engineers KTV audio concept design, design principles box with multi-angle, so quick and easy on-site installation debugging, structural safety and reasonable.
