Take your audio production to the next level with the JBL 306P MkII Powered 8" Two-Way Studio Monitor, a next-generation device that brings legendary JBL performance to every studio. Equipped with the revolutionary JBL Image Control Waveguide and refined transducers, this studio monitor delivers stunning detail, precise imaging, and an impressive dynamic range that enhances the mix capabilities of any modern workspace. The JBL 306P MkII is a testament to JBL's patented technologies derived from the 7 Series and M2 Master Reference Monitors. With its sleek, modern design, this studio monitor delivers outstanding performance and an enjoyable mix experience at an accessible price. The JBL 306P MkII is a new edition of the 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. The patented Image Control Waveguide reveals impressive detail, ambience, and depth in your mixes. This groundbreaking innovation ensures an acoustically seamless transition between the low- and high-frequency transducers and provides an immersive soundstage with precise imaging. The JBL 306P MkII is equipped with acclaimed 3 Series transducers that now perform even better. Experience 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. The JBL 306P MkII is ready for the most demanding production styles right out of the box. Dual integrated Class D power amplifiers, custom designed by JBL 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. The JBL 306P MkII 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 306P MkII to tailor it to room acoustics or personal tastes. 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. The design of the 306P MkII leverages over 70 years of JBL acoustic expertise to create a refined studio monitor at an outstanding value. JBL Professional studio monitors are designed for reliable performance, even when projects push your gear to the limit. As a result, you can depend on 306P MkII monitors to deliver consistently excellent sound reproduction for years to come.

After at least 6 years and 3 rooms, I am so glad that these are still available and supported for people entering the audio professions. I have them on stands with plenty of room to "breathe" and they impress me more each year. The best validation (besides the sound) is that I had a failure; yes, the power indicator would not illuminate but no big deal because I called JBL and they send a VERY reasonably priced replacement part from Texas, USA. JBL offers replacement parts instead of stiffing you to replace both of your monitors. Awesome neutral, non-fatiguing sound, exceptional support, good pricing... just buy them for your studio or home theater and enjoy life!

more than I expected

Excellent performance!!! And it meets all the expectations one has of the product.

Great features!!

I am enjoying these monitors in my home studio. Originally purchased without the subwoofer (LSR310S), but added that and now is feels complete. Very happy with the quality and sound for my application. Crispy highs and great bass frequency response (more so with the addition of the LSR310S).

Great Quality / Sound

It is said that ?You are as good as the tools you work with? and I couldn?t be happier with these monitors.
As a passion, I do remix work in my home studio and for the first time I am able to listen to my projects and hear amazing sounds I didn?t hear before. My work has improved so much more because of all the details these monitors provide.

Precise and dependable!

Great monitors, I'll be buying more in the near future.

Great Sound

These sound fricken amazing with my project debut carbon record player! The quality is great and man they are loud!

I bought these a few weeks ago, and these have to be the best bang for the buck. The sound even across frequencies, bottom end is tight for a small near field, quiet operation, and light! I?m very satisfied, and would absolutely recommend!

Great for the money!!

I bought to produce my songs and I know I have a pair of the best monitors I could buy in its price range and even more expensive ones would not be as suitable for my needs (EDM/Urban. And yes, there is a hiss that is just normal for professional monitors and they are inaudible as soon as any audio signal comes from them.

Great bass response and amazing stereo field

Good Sound, quality, comfort & Bass. The best speaker ever I have.

Good Sound

The price was good on sale as much as the 305's. I like that the volume knob has the bumpy stages that way a pair can be accurately synchronized to the same volume. The highs and lows frequency adjustment switches are also a life saver since my room is not sound treated. They sound great honestly, they really shine when playing music but as a multimedia speaker for live tv they arent as good. I used them for my tv and everything sounds better but in movies dialogue is always much louder than any of the mids in the background. There are a few issues but not gamebreaking. 1. there is a hiss or fuzz thats audible when you get up close to them, this doesnt bother me b/c i sit far away (5-7ft). 2. There is no mesh screen for protection and that means you have to make your own. 3. The rear port looks really underdeveloped, what i mean is that the port is basically just a hole. When i shined a flashlight i could see everything on the inside. The tweeter is super exposed so if you have kids make sure they never get back there. Also the tweeter is not isolated from the bass in there so there could be distortions caused by strong bass. The tweeter also looks really simple from back there like it didnt cost much to make and install. Anyway im still very satisfied and love the jbl quality of being confident in turning up the volume without fearing of cracks n popples. I would recommend for their next iteration to add a second tweeter or a mid range tweeter. Make it a 3-way speaker to blow up all the mids to be as strong as the highs.
