I used to have a JBL 305s to use with my Modular synth away from the main synths, but had to get rid of them for a period of time where I had no space for them.Since I had a good experience with them, I jumped at the change of getting the 306 mkII on sale. If you're looking for a completely flat response from your monitors, I don't think this would be the right set for you.The shining quality of these is that they pack quite a punch low down, so if you wanted a reasonably sized speaker setup without having to add a sub, this is what you're looking for. I think of them more as speakers I can noodle and jam with, rather than for any serious production. It's not that the JBLs are bad as monitors, you can EQ them to adjust their response, and easily use them for ... MoreI used to have a JBL 305s to use with my Modular synth away from the main synths, but had to get rid of them for a period of time where I had no space for them.Since I had a good experience with them, I jumped at the change of getting the 306 mkII on sale.

I absolutely love these things!

Amazing Speaker, amazing quality!

The speaker quality is really good! I bought 2 to balance out sound! I have 4 studio monitors total and the sound between all 4 are just amazing! One complaint I will have is the led on the front will die after some time but that doesn't change the speaker quality! Amazing speakers!!

Excellent for the price.

These speakers have been praised by many, and I think for very good reasons. JBL did almost everything right. OK, they are not the M2 and also not the series 7, but at this price point who can pretend more! Here are my positive impressions:- The sound is much bigger than the size of the speakers would suggest, with more extended bass than I would have expected. I would suggest to listen to them with some well recorded music for some time to get used to their sound before doing some work, otherwise your mixes will likely sound too thin.- The tweeter is also doing a very good job, the treble is sweet and well controlled. Don't expect the forward and aggressive 'JBL sound' (such as the 4408). Again, give them a listen before doing work, otherwise your mixes may end ... MoreThese speakers have been praised by many, and I think for very good reasons. JBL did almost everything right.

Don't expect the forward and aggressive 'JBL sound' (such as the 4408). Again, give them a listen before doing work, otherwise your mixes may end up sounding too metallic and shrill.- The very short wave-guides seem to actually work quite well. In the near field the sound stays well balanced also off-axis. In the horizontal plane, I would say up to at least 45° off axis, in the vertical plane the dispersion is much narrower (say perhaps 30°) but still well controlled. Make sure the loudspeaker are installed roughly at ear level.- Also in the far field the sound remains well balanced. Even at a distance of a few meters the sound is still clear, with good high frequencies also off axis. Again the wave-guides are working well at controlling the dispersion.And here a few negative ones:- I don't like much the bass reflex port on the back. You need to place the speakers well away from the back wall, otherwise the bass becomes boomy and somewhat less controlled. Well, not too bad.- There is some hiss coming out of the tweeter. You will hear it up to some 50cm-1m distance. Lower noise amplifiers would have been good.- At high volume the bass becomes a bit hard and distorted. Well it is to be expected, it's the usual trade-off, either you get deep bass or loudness, not both.

Exceptional value for the money

For the price you can't beat these speakers. The sound quality is great. The low end is surprisingly good, but not too "boomy". The high end is slightly weak, you can definitely tell it's not a hard dome tweeter, but it also seems to miss some of the warmness commonly associated with soft dome tweeters. There are compensation switches for both the low and high end so you can make adjustments based on the room, placement, or your preference. These switches really make a difference and allow you to dial in the sound and give you flexibility. The output is good but there's very little headroom. The amplifiers need to be much bigger. Still, these speakers are an excellent choice for the money and I still can't find a better speaker unless I spend $400-$500. I wish JBL ... MoreFor the price you can't beat these speakers.

Good Value

Generally you get what you pay for. With the 306p's you get your money's worth but not the ultimate in studio monitors for which you'd have to pay more. On the plus side the output level is substantial. It takes a bit of adjusting to optimize the performance of these speakers to your listening environment. Low frequency roll off is likely needed if you place these speaker against a wall. The high frequency driver is pretty artificial with a lot of "paper" sound in the tweeter's response. Using the high frequency roll off will be essential for sustained listening. You'll need a subwoofer with these speakers, not because there is an inadequate low frequency response but because you'll want to hear the sub frequencies happening below the useful musical low end provided ... MoreGenerally you get what you pay for.

With a sub, there's plenty of punch in the kick drum and bass guitar. Disruptive mud can be more easily identified and addressed when a subwoofer is used. One annoyance is the constant low level high frequency hiss that emanates out of the speaker from the built in amplifier. You might not notice the amplifier noise in a noisy environment but in a quiet control room the hiss can be a bother. If you're on a tight budget, these speakers are a good value.

Great Home Monitor Package!

I haven't used the speakers a lot yet, but everything so far is great! I very much appreciate having the cables, isolation pads and the Senal controller as part of the package. The cabinets are larger than I expected so I will eventually buy some floor stands and put them behind my work table to give me a bit more setback. Very happy with the purchase but I would also consider the smaller speakers.

Great sound, great price

Currently these monitors are on my desk, horizontally configured, with signal coming from a SMSL M200. Sound is what I was expecting after reading numerous reviews on monitors. The bass at 0dB (not dampened with the switch on the back) is quite robust, all sounds are punchy/clear, and imaging is great.These were bigger than I expected, because I initially was going to buy the 305p's and didn't read the dimension specs. When they arived, the boxes for each speaker was about the size of an AC window unit box. I probably could get better sound if my desk was larger and I was further away from them. My desk is 48 wide by 24 deep and if it was any smaller I wouldn't be able to fit them. Standalone speaker stands or a couple of tall nightstands could help someone get ... MoreCurrently these monitors are on my desk, horizontally configured, with signal coming from a SMSL M200.

I have not tried to really push them. I mostly keep the volume nobs on the speakers at 50%, and the DAC at -20dB. It's plenty loud for me at this point and I don't hear any artifacts. Another option I should consider is dropping the bass response to -3dB and then turn the DAC up to -15dB for more focus and clarity in the mids/highs for Classical, Folk, or other genres while minimizing noise pollution.

I hear no hiss

Just chiming in on this since I've read the negative reviews. I've had these for about a year. I hear no hiss. I am a pro video editor with 30 years experience and thousands of mixes. I've used just about every common studio speaker either in my studio or with clients over the years. Newsflash, these are not as good as the ones that cost 5x as much, but they don't cost 5x as much. And the difference is not 5x, more like .5x. Can't imagine not being satisfied with these in a home studio environment. The whir of your computer and GPU fans will drown out any appreciable noise (of which there is not a noticeable amount). Not sure anyone is mixing albums in high-end soundproof studios on these...on the other hand people are going to listen to that album on sucky ... MoreJust chiming in on this since I've read the negative reviews.

Incredible value, great sound

I consider myself an audiophile and have two decades of studio experience and sound engineering. After reading reviews here I made the decision to give JBL a shot as I was just building a small home studio and couldn’t spend thousands of dollars on monitoring. I feel this package is worth a few thousand in sound. The speakers are beefy and the sound is crisp and seemingly flat, not overly colored. The mixes that I have that I know are warm, are warm. I’ve heard these mixes on top of the line studio monitors and am seriously impressed at how they sound on this system. You can’t beat the value you get here for this price. I plan on taking great care of these speakers and hoping for a long life, but can’t comment on their longevity until I’ve had them for several ... MoreI consider myself an audiophile and have two decades of studio experience and sound engineering.

The kick sounds I’m getting are very accurate to what was recorded and how the drums sounded in the room. Go for it if you’re thinking about it!

JBL 306 MKII's are perfect for my needs

I already own a set of the JBL MKII 305's. I waited to buy them until the combo deal that Adorama had was back in stock. Two speakers plus 3 cables (two XLR and one 1/4" mono to 1/8" stereo) and isolation pads for less than the cost of the two speakers separately - I'm convinced.The JBL 306 MKII's are perfect for my needs. I use them for computer listening, some recording work, as output for guitars going through various boxes and through my DJ mixer (the mixer has direct XLR outs - so I can run my source to the mixer and right out to speakers).They work and sound great for all those things. Both the MKII 305's and 306's have great bass for their size. For my computer I have added a AudioQuest DragonFly Red DAC going through the JBLs - and it sounds great.
