B-28

The speaker has a rated power of 1200W continuous (4800W program) and a sensitivity of 105dB / W / m. The highly efficient B-28 provides super strong impact, high digital output and low distortion. The B-28 uniquely combines different technologies to keep the voice coil at a lower temperature, avoiding power compression and not reducing output at high volume levels. The electric structure of each drive is located in the port. Using our famous Active-Air cooling technology, the air flowing outside the port quickly removes the heat of the components. In addition, cone motion drives air through the open-hole magnet pole pieces, further cooling the electric structure. BCL (balanced cone loading) improves the linearity of the system by balancing the air load before and after. The third harmonic distortion of 40V (50% power) does not exceed 1.9% on its operating range. The cabinet has a solid internal support, which can reduce the sound energy loss caused by the vibration of the cabinet.
