Dual integrated, custom Class-D amplifiers provide 112 watts of power for high output and dynamic range Soundstage is surprisingly deep (at least, with experience typically only lending itself to the concentric drivers like Kef in this regard). The MkI versions of JBL’s 3 series monitors were highly regarded for offering excellent sound quality at affordable prices. Now upgraded to feature refined drivers and a new Boundary EQ adjustment setting, the MkII versions improve upon the original design. When used alongside Pro Tools 12 and our interface for mixing, we had a very easy time balancing mixes, adjusting equalization settings, and adding compression, finding that our mixes always translated as expected to other devices and listening settings. Our only gripe was that the speakers had a small amount of amp hiss when in a very quiet room with no sound playing, but that’s to be expected of any powered speakers with this volume potential and at this price point, and it became unnoticeable whenever sound was playing at any volume.

Review: JBL 306P MkII - MusicTech

The below graphic indicates just how much SPL is lost (compression) or gained (enhancement; usually due to distortion) when the speaker is played at higher output volumes instantly via a 2.7 second logarithmic sine sweep referenced to 76dB at 1 meter. The signals are played consecutively without any additional stimulus applied. Then normalized against the 76dB result.Flexible connectivity with balanced XLR and 1/4" TRS inputs, +4dBu / -10dBV input-sensitivity switch and adjustable volume control Response is excellent other than the dip around 1.6 kHz. I really like to see manufacturers do better in this region as it is so important to perception of fidelity in my opinion. Fortunately the dip is narrow. Here is the near-field measurements: As in most mixing environments, having a balanced room to place the speakers in is a key component to crafting an accurate mix, but the JBL 3-series speakers themselves were easily up to the task of making excellent mixes with plenty of depth. Simply put, there’s no reason someone with sufficient skill couldn’t mix a fantastic sounding album, podcast, or other project on these speakers. Unlike comparable options we’ve heard in this price category, the 306 MkII are very transparent and honest — just what you need to do proper work that will sound good anywhere. Warranty information Long term testing results in speaker magnet/baskets so hot they can almost burn your hand. (not saying he needs to go that far).

I just got these speakers. I produce both music and film. I absolutely love these little guys. Clean and true sound. I’d buy them again in a heartbeat! Integrated custom Class D amplifiers deliver 112 watts (LF: 56 watts; HF: 56 watts) of power for high output and dynamic range Considering that this is a ported cabinet — ports essentially buy speaker designers some extra LF extension at the cost of a degree of time smearing — the bass sounds full, solid and well-controlled. My tests were done sitting the speakers on a pair of Primacoustic Recoil Stabilizer platforms; a decent support is essential to keep the bass end as tight as possible. The four self-adhesive rubber feet that come with the speaker really don't do it justice on their own but may be useful in stopping the speaker slipping when placed on a suitable platform or stand. Hmmm. I look at the measurements and see a distortion factory. Yet they 'sound great' and are recommended. If both observations are correct, what else can I conclude but 'distortion doesn't matter'..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. The midbass does some things I do not like at all and generally sounds quite resonant. Let me give some specific examples: But that is a relatively high level, to begin with, and you won’t want to mix at that level for extended periods. But it is still worth highlighting if you want to crank it up occasionally. As with sub-bass delivery, pairing the monitors with a subwoofer will give you much better performance at higher levels. It isn’t a huge deal as the surface is easy to clean but if you tend to move your monitors around a lot or are rough with them, expect them to look worse for wear sooner rather than later.
