Sixteen enclosures in four rows were used in 2007 at one of the stages of the Ultra Music Festival, to reduce low-frequency interference to neighboring stages.  Typical filters involve some overlap in frequency ranges; a steep 4th-order 24 dB/octave low-pass filter is generally desired for subwoofers in order to minimize the overlap region. For greatest efficiency and best coupling to the room's air volume, subwoofers can be placed in a corner of the room, far from large room openings, and closer to the listener.
