The PRX725 is the next step in the highly successful PRX Series and introduces the first use of JBL’s patented Differential Drive® Technology with ferrite drivers. Differential Drive technology incorporates lower mass in the ferrite magnet for reduced weight while maximizing power amp efficiency for greater heat dissipation and increased power handling. Powering the PRX725 is a 1500 Watt high performance, exceptionally low distortion biamplification system engineered to deliver clean power with maximum headroom to efficiently deliver smooth high frequencies and rich, deep bass response even at very high sound power levels. Compact, ultra-lightweight, the PRX725 uses JBL’s tour tested technology throughout so you can trust it to deliver a lifetime of reliable performance.
