What’s New in 3 Series MkII?
MAKE YOUR MARK WITH SUPERIOR STUDIO MONITORS
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 optimised 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
Image Control Waveguide
PRECISE DETAIL AND A BIGGER SWEET SPOT
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
ENHANCED MIXING ACCURACY
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.
- Three different sizes available: 305P MkII (5"), 306P MkII (6.5") and 308P MkII (8")
- Next-generation JBL transducers for optimised 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
BIG SOUND OUT OF THE BOX
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
TAILORED SOUND TO FIT YOUR STUDIO
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.
- Customise 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
Flexible Connectivity for Your Studio
PROFESSIONAL FORMATS FOR EASY INTEGRATION
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
