Loudspeaker is suspended from hub and used to broadcast masking, paging and/or music. The LA-1 model is very flexible and used throughout most LogiSon acoustic network installations. The custom clip allows the length of chain to be adjusted without tools. Slack cable retracts into the enclosure, ensuring tidy installation. The full-range driver provides output exceeding the typical masking spectrum of 100 to 5000Hz including the lower frequencies needed for comfort.
