    • Excellent intermediate studio monitors!
Size: 306P MKII
These are really excellent intermediate studio monitors! A lot of the monitors at this size have really questionable XLR jack durability so they wear out fast but the JBL 300 line did a fantastic job with these! Double reinforced sleeve ports and the pins are solid as can be! Sound quality is FANTASTIC! and the box design is excellently desinged! Very good air displacement! They make big clear sound and don't vibrate all over the place so you can comfortably and safely put them on speaker stands and not stress about then falling off! They are also rated for 600W max draw but ive not had any issue with them giving ground fuzz even at max load! (I would advise letting them warm up before cranking them to full blast!) The voice coil and motor seems to be fantastic design as well as i dont hear connection pops even when I forget to nuke the volume before powering them down! Over all... id say these are worth every penny and I plan to grab 2 more once i get the Scarlett 218i16 the push them! ... show more

    • Great Value Monitors
Size: 308P MKII
For the money, I can't imagine anyone getting more at this price range. The speakers have a balanced sound and just sound great. I don't have any doubts in my mixes when I work on these. I've seen confusion in reviews as to whether a subwoofer is needed or not. It's my assumption based on what was stated they might be first time purchasers. The bass is really punchy and clear with detail, but you'll need to supplement the low end with bass you feel with -- a subwoofer. You can still hear sounds down to the 40-50hz range, but to feel the sub-bass in your chest you'll need a subwoofer to even out the experience. If I crank up the volume on the JBL's the bass can get close to my subwoofer. However, accuracy is important here, not volume. I'm on a budget so I was able to cheat and use a Y cable to route the the L/R audio from my Focusrite to my old subwoofer. In the future I'll be looking to upgrade and drop the splitter. Reviewers mentioned a hissing sound in the speakers, in my experience I never noticed it over the slight hum of my computer unless I position my ears less than 12" from the speaker. The speakers are without a doubt sufficiently loud. I had to set the volume at 12 o'clock on the speakers, and the same position with my Focusrite. The sound filled the room entirely. One thing to keep in mind these are rear-port firing speakers. So you'll need to treat your room properly for these to work at their best for you. If that's not an immediate option you can use the Trim feature to overcome the bass bleeding through. This seems to be the issue I saw with inexperienced reviewers who were critical of clarity. One aspect that seems to get overlooked is stereo imaging. When I listen to Micket Hart - Udu Chant you can visualize the entire sound stage. The song also makes great use of panning effects which these JBL's do a good job projecting. You can almost follow the sound heard in the intro with your eyes. If you're either a first time studio monitor buyer, or looking to own some in this price range you wont be disappointed in how these perform. Excellent speakers! I'd recommend all future purchasers and current owners to check out the AudioCheck website. They have really great ways to test your speakers! ... show more

    • Nice speakers, but have a hissing noise.
Size: 308P MKII
Overall, this is a nice speaker. It sounds as good as many other JBL speakers, if not better. The sound is clear and has a fairly good low end. In my opinion, it's worth the money. However, the reason I'm giving it 4 stars is because of the hissing noise. When there's no audio playing, it will have a hissing noise no matter if audio cables plugged in or not. I've read this issue from other reviewers and it's still a little louder than I expected. When the room is quiet, it's audible within 1 ~ 2 meter distance. I just turn off the speakers when I don't use them. If you wanna listen to them in the near field, this is something you need to consider. ... show more

    • Sounds great.
Size: 308P MKII
Nice sound, decent bass. Still bought a subwoofer to supplement. Using the setup for my digital piano, and as studio monitors. sounds amazing. Also use it as a sound system for my PC. Great all around, no complaints. Only thing Im not really fond of is the plastic covering. Its the type of plastic that gets micro scratches incredibly easily, even when wiping with a simple soft cloth. You need to use a very fine micro fiber cloth to clean. And they are dust magnets, due to the static cling. However, not a major issue overall. Just not how I would have designed these things. ... show more
