MID-BASS

MB15H401

Professional Low Frequency Transducer

PART NUMBER 11100015

Features

4-inch, fibreglass inside-outside aluminum voice coil

1400 Watt continuous program power handling

100 dB Sensitivity

40 Hz - 2 kHz Frequency range

Dual spider design with silicon based dampening control

Triple-roll surround and corrugated exponential cone geometry

Aluminum demodulation ring

The MB15H401 is a 15-inch midbass with linear frequency response characteristics and very high efficiency. The MB15H401 uses a fibre loaded exponential cone assembly along with a high excursion triple roll, constant geometry surround. The fibreglass former, inside/outside aluminum voice coil provides a very good power handling maintaining light moving mass and proper Q for bass alignment.

Demodulation ring for fastest time response and lowest distortion.

Applications

The MB15H401 is ideal for use in applications where is required good power handling, very high efficiency and perfect linearity. Is the ideal 15” woofer for midbass application in high power, compact 2 way systems. Thanks to his linearity, very easy to crossover compared to competitors 4” voice coil 15”. The robust mechanical design and optimised weight of the device make it desirable for use in fixed installation or portable professional loudspeaker systems.

Notes to Specifications

1 Program Power is defined as 3 dB greater than AES power. - 2 AES standard. - 3 Sensitivity measurement is based on a 200-2 kHz pink noise signal with input power of 2.83V @ 8 Ohms. - 4 Thiele-Small parameters are measured after a 2 hour warm up period running the loudspeaker at full power handling capacity. - 5 The maximum linear excursion is calculated as: (Hvc - Hg)/2 + Hg/4 where Hvc is the voice coil depth and Hg the gap depth. - 6 Calculated for front mounting on 18 mm thick board.
