JBL Builds On Success Of PRX Series With PRX512Mi and PRX718S Powered, Portable Loudspeakers

Bringing a new level of versatility and performance to its groundbreaking PRX Series powered, portable loudspeakers, JBL today introduced the PRX512Mi multipurpose powered loudspeaker and the PRX718S high performance powered subwoofer. These additions bring the total number of models in the PRX Series to seven and provide performing musicians, DJs and sound companies with more power and flexibility than ever before.

The PRX512Mi is a 12-inch, 2-way, truly multipurpose, self-powered sound reinforcement system, with a frequency range of 46 Hz to 20 kHz. The PRX512Mi is comprised of a 12-inch Differential Drive® woofer, a neodymium compression driver mounted to a 70 x 70-degree horn, all driven by a multichannel Crown International Class-D digital power amplifier. The PRX512Mi features 400-watt low-frequency and 100-watt high-frequency amp channels, while weighing only 18 kilos (40 pounds).

At the core of the PRX512Mi is a fully integrated DSP input section, providing mic/line level input, selectable system EQ, and a premium A/D converter for a maximum signal-to-noise ratio. The multipurpose enclosure makes the PRX512Mi ideal as a main PA or stage monitor, while a dual socket pole mount, eight standard M10 suspension points and one M10 pull-back point enables a new level of multi-functionality.

“The JBL PRX512Mi delivers a true universal solution for gigging musicians, DJs and A/V rental companies alike,” said Simon Jones, Director of Portable PA Marketing, JBL Professional. “It’s compact, powerful, lightweight and highly versatile. It’s the definition of portable PA versatility.”

Also new to the PRX family, the PRX718S is an 18-inch, self-powered subwoofer system, offering a frequency range of 33 Hz to 160 Hz, and a power rating of 1,400 watts peak. In addition to the 18-inch Differential Drive woofer, the PRX718S features JBL’s proprietary Dual-Bridge Technology™ (DBT), which directly links discrete amplifier channel outputs with each voice coil in the woofer, transferring the maximum amount of power in the most efficient way and improving the speaker’s overall performance. The PRX718S also offers a DSP input section for precise bandwidth control and limiting. Additional functionality includes a selectable high-pass filter on the stereo loop-through outputs and polarity reversal, all at a weight of 36 kilos (80 pounds), very light compared to competitive subwoofers at this price and power.

“The PRX718S delivers exceptionally accurate low-frequency reproduction right down to 33 Hz and it does so without compromising on portability,” Jones added. “Its performance-to-weight performance is unparalleled, making the PRX718S a truly high-performance, portable PA subwoofer. All in all, the additions of the PRX512Mi and PRX718S provide the successful PRX series with even more power and versatility.”
