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.
