Anyone who's experienced the legendary JBL 3 Series in a studio setting will say that they offer an incredible amount of quality without breaking the bank - and with good reason. Perfect for home studio setups, the 3 Series offers pro's and hobbyists alike a professional quality broadcast/production experience at a great price!

6.5" Two-Way Powered Studio Monitor

Well, good new folks: the new-and-improved 3 Series MkII is here, seen here as the JBL 306P MkII - a compact powered studio monitor, which makes that legendary JBL performance available to every studio studio.

Whether you own a home production studio, or you're a hobbyist/prosumer wishing to engage in music production, podcasting, vlogging, YouTube and more, if your studio space is limited then the JBL306P MKII represents the ideal solution for you!

Why the MkII?

Subsequent to their release, the original JBL 3 Series gained a reputation for their high quality to cost ratio, which saw an awful lot of hobbyists and budding professionals using them for their work. However, never one to rest on their laurels, JBL continually look to improve upon what came before, and so have included a handful of new features and improvements in a successful attempt to one-up themselves.

Such upgrades include those final improvements to the transducers, the inclusion of a much-requested feature, and application of the latest manufacturing learning. All of this and more has gone into producing a brand new edition of a popular studio monitor, with improved looks and sound being added to the best qualities from the original.

Patented Image Control Waveguide

Originally developed for JBL's flagship M2 Master Reference Monitor, the groundbreaking Patented Image Control Waveguide allows you to reveal impressive details, ambience and depth into your mixes. Offering an acoustically seamless transition between the low-and high-frequency transducers, this technology provides an immersive soundstage with precise imaging - you know that you're going to get a crystal-clear representation of your mix with the JBL 306P MkII.

Good Monitors Mean a Good Mix

With its new and improved 3 Series transducers, the JBL 306P MkII provides you with breathtaking performance capabilities.

Thanks to the long-throw 6.5" woofer and the patented JBL Slip Stream low-frequency port, you get to hear deep, accurate and tightly controlled bass frequencies. On top of this the woven-composite 1" Neodymium tweeter will throw soaring, immaculately detailed highs into the mix too.

Featuring a faster HF transient response, greater low frequency linearity, and lower harmonic distortion than previous models , the JBL 306P MkII is a studio monitor you can trust!

Plug And Play Functionality

No matter how simple or demanding your production needs, the JBL 306P MkII is ready for it right out of the box. Thanks to its dual integrated Class D power amplifiers (custom designed for each transducer), you get a generous dynamic range whatever your project.

Whether your needs revolve around music production, podcasting, vlogging, or even cinematic sound design, the JBL 306P MkII allows you to hear exceptional detail at any volume, even at peak SPLs. Just plug in, power on, and you're ready to go!

Versatile, Flexible, and Reliable

Thanks to the innovative new Boundary EQ and 3-position HF Trim switch, you can adjust your JBL 306P MkII to perfectly match the dimensions and acoustics of almost any room you choose to work in. Add to this the balanced XLR inputs, adjustable input sensitivity, and that world-renowned JBL reliability, and you have yourself a powered studio monitor that suitable for any situation, in any environment.
