It can be positioned horizontally for use with a 35 mm mounting pole for a full-range speaker, or vertically for a smaller footprint.
The cabinet has an integrated carry handle and a 120 Hz low-pass filter with a 12 dB-per-octave slope, with the option to select a full-range input. The frequency response is 55–150 Hz.
