An Outstanding Monitoring Solution!

JBL LSR308 active studio monitors are a great solution for any serious audio engineer or music producer. They're great for mixing music in your DAW software, editing video, or any other task that requires precise, accurate, detailed sound. JBL designed the LSR308 with advanced features from their flagship M2 Master Reference Monitor and has even earned the acclaim of renowned engineer Frank Filipetti. An innovative Image Control Waveguide creates a well-defined and incredibly dimensional stereo image. Ask anyone at Sweetwater: from surprisingly rich lows to smooth highs, you'll find it easy to make great-sounding productions with JBL LSR308 active studio monitors.

JBL LSR308 Active Studio Monitor at a Glance:
  • Incredible stereo imaging thanks to an innovative waveguide
  • Ported design means more accuracy at low volume levels
  • Wide sweet spot equals a better studio experience
Incredible stereo imaging thanks to an innovative waveguide

JBL borrowed innovative elements from their flagship M2 Master Reference Monitors to give the LSR308 incredible sound. The Image Control Waveguide design is one such feature, and it helps the LSR308 have a deep sound stage as well as great detail. Said another way, not only can you clearly hear left /right placement of instruments in the mix, you can also hear depth created by the use of effects and mic placement. This gives you an accurate representation of how your mix will sound from earbuds, headphones, and a broad range of playback systems.

Ported design means more accuracy at low volume levels

Checking your mix at low volume levels is a great way to check your overall balance, but many monitors will suffer in the bass regions when dealing with low monitoring levels. The JBL LSR308 uses JBL's patented Slip Stream low-frequency port for accurate bass response at low playback levels. The double-flared port shape also reduces the turbulence that some ported designs cause, meaning that bass response remains pure when you turn the LSR308 back up.

Wide sweet spot equals a better studio experience

Hey, we're engineers, musicians, and producers too - we know you don't spend every second of your studio time in the perfect mixing position. JBL LSR308 monitors have a wide sweet spot, which means there's less variation in what you hear when you're not in the perfect position. Especially if you have clients in the room, you want consistent sound throughout your studio, and you'll like what you hear from the LSR308.

JBL LSR308 Active Studio Monitor Features:
  • Bi-amped active studio monitors with 8" LF driver and 1" HF driver
  • Exceptionally wide frequency range for more accurate mixes
  • Image Control Waveguide creates a detailed and dimensional stereo image
  • HF and LF trim controls let you fine-tune the speakers to your room's acoustics
  • XLR and TRS balanced inputs give you low-noise performance with your studio gear
  • Sold individually
The JBL LSR308 is a great mixing solution for any studio!

Great sounding monitors

I think that these monitors have an overall honest sound to them. Nothing in the sound is over exaggerated.

I've been using these for about 4 months, and i have to say i'm pleased by the quality of the results. At college, we have a studio equipped with high category system, including two Genelec 1032B and two 1238A three-way Smart Active Monitors of the same brand and the mixes translates really well from my LSR308 to that system, off course the triamplified system ends up showing me things i didn't listen back in my room, but in general, the mix is well transfered. One more thing to highlight is the amazing center image, and therefore the great general stereo image. You will get a total sense of what's in where and how is the balance on your mix thanks to that. For the cost, they are a great choice for first monitors.

It's True. They're Really That Good.

Before purchasing, I always check the customer reviews. The ones at Sweetwater on the 308's were obviously quite good so I decided to buy based on the JBL reputation and the positive comments here. The 308's are simply outstanding, superb studio monitors. That you can have this level of sound quality in this price range is shocking. I have been auditioning music all day and am totally impressed with the JBL's. First, the full audio spectrum is represented in a very balanced, pleasing manner. Full, rich sound.The stereo separation and the distinct tone & position of instruments in the mix can be heard and seen., You can literally visualize exactly where an instrument sits in the left/right mix as well as its depth in the audio field. I found each monitor to be carefully constructed. Quality control is evident throughout. After experimenting with room placement, I found that the built-in eq filters were perfect in the flat (default) position. Since I generally mix at low to moderate volume levels, I found the sound to be balanced and the tonal representation to be accurate at both low and moderate volumes. A hallmark of good monitors is that they reveal nuances and fine details in a recording that most consumer level speakers cannot deliver. The JBL's definitely excel in that area. Songs I have been listening to for years are now heard with more clarity. To close, I really have to add to the general positive & enthusiastic responses of the majority of commenters. The 308's are a huge value. I highly recommend them.

It' hard to believe, but these are the real deal.

I own a pair of Dynaudio BM15a monitors that I've trusted more than any other studio monitor. I've needed a second set of monitors for a while to A/B my mixes and figured I would be spending at least a couple thousand on a good, honest, natural sounding set monitors. I started to see comments popping up everywhere about the JBL LS308's and I could never find one bad thing that anyone had to say. I thought people may be giving JBL the benefit of the doubt because they are good for the price, but the truth is these are AMAZING monitors that translate perfectly and will compliment any studio setup. Especially if you wanted to go with 5.1 Surround it's an incredible deal. If you have doubts because of the price, then let me clear your mind and assure you these are worth much more than the asking price.

Sweetwater Advice

Jonathan Casarow

I use the LSR308's in my studio for mixing, mastering, and even composition. They outperform other monitors in their price range and in many cases, those at a higher price point. I really get a true representation of what's happening when using these monitors.

Carson McClain

After doing a shootout against several major brand name speakers in this price range, the JBL LSR308 monitors won hands-down. I've now added them to my personal home studio as my main production speakers for electronic music.
