The bi-amplified LSR6325P is based on 5.25-inch high-excursion low frequency transducer powered by 100W RMS amplifier and 1-inch damped titanium-composite high frequency transducer powered by 50 Watt RMS amplifier. Housed in cast aluminum enclosure with dark graphite finish of LSR6300 line, LSR6325P produces very flat frequency response +1.5dB/-2dB 20kHz to 70Hz with bass extension –10dB at 48Hz and peak SPL of 109dB at 1 meter. The new LSR6325P includes innovative technologies to overcome problems in the room and optimize response at the mix position. Due to irregular off-axis response, a speaker which measures flat on-axis in an anechoic chamber, may not produce flat response at the mix position. JBL’s Linear Spatial Reference technology ensures that the mid and high-frequency content that reaches the mix position is also smooth and accurate. This is accomplished by engineering into system +/- 30 degrees horizontal, and +/- 15 degrees vertical, radiated response. Using LSR technology, the mid and high-frequency response is flatter at the mix position, regardless of working distance.
