JBL Professional Reliability
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 JBL’s strenuous 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 306P MkII monitors to deliver consistently excellent sound reproduction for years to come.
Flexible Connectivity
Offering both balanced XLR and 1/4" TRS inputs, and adjustable +4dBu/-10dBV input sensitivity, the 306P MkII offers flexible, professional connectivity options to provide easy setup while maintaining your signal integrity.
Why MkII?
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 project at JBL, there’s always a handful of features or improvements that the engineering team can’t squeeze in before going to production. 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—a new edition of this popular studio monitor that retains the best qualities of the original, but now looks better, sounds better, and provides transparent sound in even more production environments.
Your Mix is Only as Good as Your Monitors
To help you make the best mix decisions, JBL equipped the 306P MkII with acclaimed 3 Series transducers that now perform even better. Hear deep, accurate and tightly controlled bass thanks to a long-throw 6.5" 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.
