Building on JBL legacy of high-quality sound performance, the 3 series Mk II represents an upgrade of the impressive LSR3 series. These compact, professional quality, powered studio monitors retain the LSR3 series' image control waveguide for incredible detail and imaging, and the broad sweet spot that means you get optimal sound even off-axis. The Mk II series now features updated high-frequency (HF) and low-frequency (LF) transducers, which respectively provide optimized damping for superior transient response and greater linearity that allows impressively deep bass with lower harmonic distortion. Upgrades also include new boundary equalization (EQ), which restores neutral LF response when speakers are placed on the work surface and adjacent walls. Hear for yourself why JBL is legendary in sound performance and quality!

  • Featuring patented technologies derived from the JBL Master Reference Monitors.
  • Updated High Frequency and Low Frequency transducers - New design improvements result in optimized damping for superior transient response and impressive deep bass plus accurate, crystal-clear highs, with lower harmonic distortion.
