Since their release, word has spread on the quality and value found in the original JBL 3 Series, resulting in wide adoption from hobbyists to high-end professionals working in music, film, post, and broadcast production worldwide. With such an obvious hit, you might ask, “Why update now?” On every JBL project, there’s always a handful of features or improvements that the engineering team can’t squeeze in before going to production, and 3 Series was no different. When the opportunity presented itself, we decided to make those final improvements to the transducers, add a frequently-requested feature, and apply the latest manufacturing learnings. The result—new editions of these popular studio monitors that

retain the best qualities of the originals, but now look better, sound better, and provide transparent sound in even more production environments.

• Next-generation JBL transducers for optimized transient response and improved linearity
• Sleek, modern design provides a dramatic flair to any studio
• New Boundary EQ delivers better bass performance when monitors are placed close to walls or corners

Reveal impressive detail, ambience 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 the low- and high-frequency transducers and provides an immersive soundstage with precise imaging. Offering a broad sweet spot and neutral frequency response, 3 Series monitors deliver a crystal-clear

representation of your mix—revealing subtle details, even when listening off-axis.

• Detailed imaging and a broad, room-friendly sweet spot
• Neutral in-room response for better accuracy
• Same patented design as used on the M2 Master Reference Monitor

To help you make the best mix decisions, we equipped all the monitors in this series with acclaimed 3 Series transducers that now perform even better. Hear deep, accurate and tightly controlled bass thanks to a long-throw woofer and the patented JBL Slip Stream™ low-frequency port. Enjoy soaring, immaculately detailed highs via the woven-composite 1″ Neodymium tweeter. JBL engineers took things to the next level with faster HF transient response through fine-tuned ferrofluid damping, and greater low-frequency linearity and lower harmonic distortion, courtesy of an enhanced woofer design. The result is a studio monitor you can trust—with unmatched peak handling, stunning dynamics

and neutral frequency response that’s unbeatable in its class.

• Next-generation JBL transducers for optimized transient response and improved linearity
• Patented Slip Stream™ low-frequency port and long-throw woofers provide superior bass performance
• Woven-composite 1″ Neodymium tweeter for detailed and accurate highs

JBL 3 Series monitors are ready for the most demanding production styles right out of the box. Dual integrated Class D power amplifiers, which we custom designed for each transducer, give you generous dynamic range for any project. From music production and podcasting to cinematic sound design or daily vlogging, enjoy the output and power you need to hear exceptional detail at any volume-even at peak

SPLs. Simply plug in, power on, and start creating.

• Dual integrated, custom Class D amplifiers
• Superior dynamic range
• Reduced distortion and extended frequency response

The dimensions and acoustics of a room can have a major effect on sonic accuracy, and that’s why the JBL 3 Series family lets you adjust the response to fit your studio. The new Boundary EQ attenuates the low-end boost that can occur when you place monitors directly on the desktop or near walls. The 3-position HF Trim switch allows you to adjust the high-frequency response of the monitors to tailor them to room acoustics or personal tastes.

• Customize monitor response to fit your workspace
• Boundary EQ compensates for low-frequency variants introduced by the environment
• HF Trim switch adjusts high-frequency output to room acoustics or personal preferences

Offering both balanced XLR and 1/4″ TRS inputs, and adjustable +4dBu/-10dBV input sensitivity, monitors in the 3 Series family offer flexible, professional connectivity options that provide easy setup while maintaining your signal integrity.

• Compatible with professional connectivity formats
• Balanced XLR inputs and 1/4″ TRS inputs
• Switchable between +4dBu and -10dBV input sensitivity

The 3 Series family design leverages over 70 years of JBL acoustic expertise to create refined studio monitors that deliver outstanding value. While other manufacturers use off-the-shelf components, and make subjective decisions about the sound, we build speakers that squeeze every ounce of performance from each component to deliver efficient, accurate sound reproduction. Monitors in the 3 Series are designed to the JBL Linear Spatial Reference criteria—a series of 72 individual measurements taken 360 degrees

around each speaker to ensure a faithful reproduction of your mix, whatever your listening environment.

• Engineered to JBL Linear Spatial Reference design criteria for outstanding accuracy
• All custom designed—no off-the-shelf components
• Leverages JBL expertise for efficient, accurate performance

JBL Professional studio monitors are designed for reliable performance, even when projects push your gear to the limit. Before being approved for production, 3 Series monitors must first pass our strenuous JBL Power Test. Each model is required to perform flawlessly at maximum volume for an unheard-of 100 hours—without failure. As a result, you can depend on 3 Series monitors to deliver consistently excellent sound reproduction for years to come.

• Strenuous JBL 100-hour power test ensures long-term reliability
• Dependable and consistent performance
• Legendary JBL build-quality
