It’s also immediately clear that the Image Control Waveguide is playing an important part in the room-filling sound, as the stereo image remains coherent without being focused into a tight, central sweet spot. The Waveguide also does a superb job, ensuring fine integration between the mid/bass and high-frequency drivers, as moving my head vertically up and down a single monitor’s front baffle reveals no phase-related issues. Big sound, small speaker But for recreational listening, as Amir noted, those kinds of narrow anomalies really aren't as much of a problem as you might think from looking at a graph. (I was relieved that his subjective impressions matched up with mine. I've seen people freak out over that 1.6khz dip when looking at graphs alone) Subjective listening varied between the nearfield at 1 meter and the farfield at 4 meters. Subjective listening was conducted at 80-95dB at these distances. Higher volumes were done simply to test the output capability in case one wants to try to sit further away. My recent discussion with Earl Geddes where he recommended one minute on, measure, another minute, measure. Under the hood, JBL has also tweaked the tweeter and woofer, aiming to provide a more linear frequency response at higher volumes. Each speaker is powered by two 56-watt class D amplifiers (one for each woofer, one for each tweeter), providing a huge amount of volume for such a small-profile speaker. As with the previous iteration, you can get the new 3-series in 5 inch and 8-inch woofer variants alongside a 1-inch tweeter, but the company has also added a 6.5-inch version for the 306P model we tested. It’s a nice middle ground that offers increased bass performance from the 5-inch but is perhaps better suited to smaller rooms than the 8-inch speakers. Riley Young/Digital Trends

The 305 and 306 somewhat ended my hi-fi buying hobby. I'll be the first to admit the woofer and tweeter are nothing special. Cheap, even. But as Amir alluded to, thanks to their excellent controlled dispersion they have a wonderful ability to sound "right" in the less-than-ideal listening rooms many (most?) of us are working with. But with the good does come the bad. There is a noticeable hiss that is louder than I would have liked, and it’s audible up to 2 feet (60cm), which could be a little annoying for longer sessions. Wrapped Around Your Finger - Glaring sound from what I assume is the synth (@ 0:26 & 0:30, for example) lights up badly. Again, I believe this is enclosure resonance.I was really surprised when I measured mine and noticed that 1.6khz dip. Seems weird for their intended use as studio monitors. Measurements that you are about to see were performed using the Klippel Near-field Scanner (NFS). This is a robotic measurement system that analyzes the speaker all around and is able (using advanced mathematics and dual scan) to subtract room reflections (so where I measure it doesn't matter). It also measures the speaker at close distance ("near-field") which sharply reduces the impact of room noise. Both of these factors enable testing in ordinary rooms yet results that can be more accurate than an anechoic chamber. In a nutshell, the measurements show the actual sound coming out of the speaker independent of the room. I understand these are really the “darlings” of the budget monitor scene. For the price, you do get a lot of good performance. However, I think it is important to highlight these concerns as they will ultimately affect a person’s final mix. For example, they may try to EQ out the midbass resonances I noted or the 1-2kHz issues or the HF shelf. If these attempts toward correcting the sound were made then the end user - who may have a much better system without these issues - would get bass that doesn’t sound right, or a 1-2kHz region that doesn’t right. I am providing this information so those who are shopping and/or use this speaker are aware of some of the things that were readily apparent to me with a variety of music genres.

Integrated custom Class D amplifiers deliver 112 watts (LF: 56 watts; HF: 56 watts) of power for high output and dynamic range JBL offers an excellent 5-year warranty on professional loudspeaker products (except enclosures). Amplifiers are warrantied for three years, and enclosures for two. The warranty covers materials and workmanship. Our Take Flexible connectivity with balanced XLR and 1/4" TRS inputs, +4dBu/–10dBV input-sensitivity switch, and volume control This is most troubling when listening to bass guitars that have notes that span the 100-300Hz region where the data also correlates to showing a downward slope in response >200Hz. Really hard for me to ignore these issues as I hear them. If you tend to listen to music with synth or isolated guitar notes then you’ll likely notice this right away; especially in the nearfield as it is less likely to get swamped out by the room effects.

Powerful and Accurate Nearfield Monitoring for Every Studio

It's rather narrow. If you're distorting at 5% across the entire frequency range that's one thing, this is another - perceptibility of narrowband stuff like that tends to be much lower than we'd think when we see those sharp peaks on a graph.

We see more of distortion between 1 and 2 kHz in the larger 308P than in 306P. The larger woofer seems unhappier in the higher range than the smaller one in 306P. Or there are sample variations.I performed over 800 measurement which resulted in error rate of less than 1% throughout the range. There is a blip around 700 Hz visible in the above graphs and we can see it as resonance in waterfall display:

JBL 306P MK II Review (Studio Monitor)

As stated in the Foreword, this written review is purposely a cliff’s notes version. For more details about the performance (objectively and subjectively) please watch the YouTube video. Acoustic measurements can be grouped in a way that can be perceptually analyzed to determine how good a speaker is and how it can be used in a room. This so called spinorama shows us just about everything we need to know about the speaker with respect to tonality and some flaws: Soundstage is surprisingly deep (at least, with experience typically only lending itself to the concentric drivers like Kef in this regard). The midbass does some things I do not like at all and generally sounds quite resonant. Let me give some specific examples: Bass response is excellent, delivering deep yet smooth low frequencies without sounding overblown or slow. Upper bass and low mids are firm and punchy with no hint of tubbiness, integrating seamlessly with the broader treble region. In our fairly large control room, best results were achieved with the Boundary EQ Control set flat. I experimented with this control and could clearly hear how it would reduce excessive bass when used in less-than-ideal situations, if they have to be placed close to a rear wall, for example.JBL has a very long history making excellent products, and we know countless people who have hung onto their older LSR 3-series speakers for years with no complaints. We expect that to be the same for the follow-up model as well. Should you buy them?
