KF series of products designed for large performance and non-linearity in professional performance box, its biggest characteristic is the high clear and bright, alto plump, bass strong, high sound pressure level, noise reduction degree is high, it can meet the voices of high degree of reduction, environmental situations required by the non-linearity.

Advanced BASSBOXPRO \ X - OVER a computer aided design of passive built-in frequency division circuit, reduced because of the external points frequency and system link to the site operation and trouble unique 16 ohms high impedance circuit design, effectively improve the speaker of the damping coefficient, reducing the need for power allocation problem of many sets of the disadvantages of efficacy, improve the efficiency of the effect, reduce the cost of investment. Ensure the stability of the system. (a power amplifier can push four speakers).

Enclosure using high-density 18 mm birch plywood produced by seiko into the trough, guarantee the integrated structure of the box body solid, durable. Body appearance with Taiwan green environmental protection paint. Paint film surface hardness, flexibility were increased, at the same time also has the waterproof, wear-resisting, corrosion resistance, adhesion characteristics such as strong, prolong the service life of the speaker. Iron network using new cross the plum flower mesh 1.5 MM antirust processing steel plate stamping die and become, within 3 MM sponge, can play a role of dust-proof, also improve the speaker's overall appearance.

Full range of sound box loudspeaker adopts the unique design of axial symmetry. A bass around each unit, middle to high unit, its advantage is about audio-visual symmetry, the axial fan cylindrical wave radiation pattern. Reduces the sound of the impact due to the phase difference.
