JBL 305P MKII Active Studio Monitor Pair

Precise Details and a Larger Sweet Spot

Experience stunning detail, ambiance, and depth in your mixes thanks to the groundbreaking JBL Image Control Waveguide. Originally developed for our flagship M2 master reference monitor, this patented innovation ensures an acoustically seamless transition between low and high-frequency drivers, creating an immersive soundstage with precise imaging. The 3 Series monitors offer a wide sweet spot and a neutral frequency response, delivering crystal-clear mix representation—even when listening off-axis.

Next-Generation Transducers

To help you make the best mixing decisions, all monitors in this series are equipped with proven 3 Series transducers that now perform even better. Thanks to a long-throw woofer and the patented JBL Slip Stream low-frequency port, you can hear deep, precise, and tightly controlled bass. Enjoy high-resolution, detailed highs with the woven 1" neodymium tweeter made from composite materials.

JBL engineers achieved faster HF transient response through finely tuned ferrofluid damping, improved low-frequency linearity, and reduced harmonic distortion with an enhanced woofer design. The result is a studio monitor you can trust—offering unmatched peak handling, impressive dynamics, and a neutral frequency response that’s unbeatable in its class.

Powerful Amplification

The JBL 3 Series monitors are ready for the most demanding production styles. Two integrated Class-D power amplifiers, custom-designed for each driver, provide generous dynamic range for every project. Enjoy the power and performance you need to hear extraordinary detail at any volume—from music production and podcasting to cinematic sound design and daily vlogging—even at peak sound pressure levels. Just plug in, power on, and start creating.

Tailored Sound for Your Studio

Room dimensions and acoustics can significantly affect sound accuracy. That’s why the JBL 3 Series lets you tailor the response to your studio. The new Boundary EQ reduces low-end boost that can occur when monitors are placed directly on a desktop or near walls. The 3-position HF trim switch lets you adjust the high-frequency output to suit room acoustics or personal preference.

Flexible Connectivity for Your Studio

The 3 Series monitors offer both balanced XLR and 1/4" TRS inputs with adjustable input sensitivity of +4 dBu / -10 dBV. They provide flexible, professional connection options that enable easy setup while maintaining signal integrity.

Renowned JBL Technology

The 3 Series design is based on over 70 years of JBL acoustic expertise to create refined studio monitors with outstanding value. While other manufacturers use standard components and make subjective sound choices, we build speakers that express every single performance aspect of each component to ensure efficient and accurate sound reproduction. The 3 Series monitors meet JBL Linear Spatial Reference criteria—a series of 72 individual measurements taken 360 degrees around each speaker to ensure reliable mix playback regardless of your listening environment.

Built to Last

JBL Professional studio monitors are designed for reliable performance even when projects push your gear to the limit. Before approval for production, 3 Series monitors must pass JBL’s rigorous performance test. Each model must operate flawlessly at maximum volume for over 100 hours—without failure. So you can count on the 3 Series monitors to deliver consistently excellent sound reproduction for years to come.
