The PM4FA-WH speaker uses the familiar response and dispersion of Atlas Sound's model FA134 high performance 4" Strategy Series® driver. This loudspeaker is the same FA series device used in Atlas Sound's popular FAP42T in-ceiling speaker package. Mounted down-firing in an attractive enclosure, the PM4FA provides natural sounding, wide coverage for low height installations while retaining very impressive full range frequency response for both music and paging applications.
