Harman’s JBL Professional is introducing the PRX700 Series portable loudspeakers. The next generation in JBL’s PRX portable P.A. line, the PRX700 Series offers improvements in power, SPL and connectivity.
The PRX700 Series comprises seven new models: the PRX710, 10-inch, 2-way multipurpose loudspeaker; the PRX712, 12-inch 2-way multipurpose loudspeaker and floor monitor; the PRX715, 15-inch, 2-way full-range main system/floor monitor; the PRX725, 15-inch, 2-way bass reflex loudspeaker; the PRX735, 15-inch, 3-way full-range main system; the PRX715XLF, 15-inch, self-powered bass reflex subwoofer system; and the PRX718XLF, 18-inch self-powered bass reflex subwoofer system.
All PRX700 Series loudspeakers are powered with highly efficient 1500W Class-D amplification, guaranteeing maximized speaker and amplifier performance, which translates into ample power, accurate dynamics and sonic purity. The PRX700 Series models feature new Differential Drive woofers that provide better heat dissipation, lower power compression and higher dynamic range versus conventional single-coil designs, resulting in better sound quality and higher SPL. In addition, the PRX700 woofers use magnetically saturated pole-pieces and an aluminum shorting ring, which significantly reduces nonlinear distortion.
The PRX700 Series features JBL’s patented waveguide technology, providing excellent coverage throughout the system’s bandwidth. The sound is smooth and consistent without hotspots, so control is optimized. All models offer coverage of 90 degrees (horizontal) x 50 degrees (vertical), which the exception of the PRX710, which features coverage of 100 degrees (horizontal) x 60 degrees (vertical).
The input panel on the full-range models (PRX710, PRX712, PRX715, PRX725, PRX735) offers a variety of features for maximum flexibility and control, highlighted by two balanced XLR, ¼-inch combination inputs and two unbalanced RCA inputs. Other features include a signal presence LED for each channel, selectable system EQ (Normal and Boost for 710, 725, 735; Main and Monitor for 712, 715); a Mic/Line switch for channel 1 and Ground Lift for CH2.
The input panel on the low-frequency models (PRX715XLF and PRX718XLF) also offers a wealth of options, including: a Signal Presence LED for each channel; a Polarity button; a Pass Thru button for Hi Pass or Full Range; a balanced XLR, ¼-inch combo input for channels 1 and 2; balanced XLR Loop Thru output connectors; and a front LED On/Off button.
The PRX700 Series is designed for traveling musicians, DJs and sound companies, thanks to a variety of tour-tested, road-worthy features. All PRX700 cabinets are built from a combination of 25 mm (on the top and bottom for added rigidity) and 18 mm, strong, lightweight poplar plywood made structurally sound with tongue and groove joints (compared to competitive models that use 15mm plywood). The cabinets also feature JBL’s DuraFlex finish, a dent-resistant 16-gauge steel grille, and lightweight glass-filled nylon handles to ensure strength and durability. In addition, rigging points, pole sockets and vulcanized feet promote easy setup and versatility.
