The Milan M15B is compact powered 15” bandpass subwoofer that extends the frequency range and increases the overall loudness of any Milan system. The bandpass design produces high bass energy within the pass band, which is tuned to reinforce bass instrument frequencies, and the steep cut-off slopes ensure an effective acoustic transition to Milan full-range loudspeakers. The onboard amplifier provides over 2,200 watts of maximum output power with plenty of headroom to power the long-excursion bass driver, allowing short term transients to be reproduced with wide dynamic range. Two discrete balanced XLR inputs plus corresponding thru connections on balanced male XLR allow a stereo system comprising of two Milan full-range loudspeakers to be operated with only one subwoofer if required, the sub-bass frequencies being filtered and summed to the subwoofer drive unit. A switchable 3dB boost is available at a centre frequency between 40Hz and 90Hz, while an overall level control allows the sub-bass frequencies to be balanced with the system. A polarity switch is provided for optimum subwoofer integration. Rear panel LEDs indicate power on, signal present, and the onset of limiting action.
