  driver in the LSR310S exemplifies JBL engineering prowess, delivering deep 
  low frequency response into the 20 Hz region, and 113 dB peak output, for 
  long periods at full rated power with no risk of failure.

  any studio monitor system to extend its low frequency performance or use it

  range of signal sources, allowing you to connect the LSR310S to high-output 
  professional equipment without any danger of input overload.
