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!

Holy crap, these things blow my mind. love love love them. The only downside is that they are pretty bright in the 2 - 4 k range and if you're going to use them as reference monitors, you should run them through a 31 band EQ using and RTA and measuring mic over pink noise to get the mid range to a flatter response.

Love my JBL LSR308 Powered Monitors

Love my new monitors. Actually bought a second set!

Best in their class

Placement is very crucial with these speakers. Make sure to have them spaced and aimed right at ear height to get the proper frequency responses. From the moment I plugged these babies in, I knew I had made the right choice. In my opinion, they should be ALOT more expensive for the quality you get.

I was recently politely shoved into the monitor market as my Mackie HR 824s were about to die in the line of duty. I looked into absolutely every monitoring option from low to high end. In my opinion the over-saturated market place is filled with hype, rhetoric, and somewhat open ended promises that turn out empty. Having been on the Mackie HR 824 for around 6 years, I was terrified of making such a move, but something had to be done as I was on borrowed time. I could have been easily satisfied with grabbing another pair of Mackies off ebay......but the more I researched the more I wanted a BETTER solution to monitoring in my studio. After spending time on the phone with my Sweetwater rep Mike Harris, he and I decided on the JBL LSR 308s. His story was identical to mine in the fact he was on HR824 for years, and was also afraid to make a move on a new set of speakers; much less a "budget" product. After spending the past week on these monitors I could not be happier. Hype aside they are wide.open.clear.revealing.and honest. These monitors have cut my work time for mixes in half if not more. The mid range is nearly identical to my NS10s, and the low end extension and stereo separation are remarkable. I can achieve a balance on these unlike I ever could on the HR824, and using the NS10s in conjunction with the LSR308s have yielded my best mixes to date. No hype. No bull. I can hear what I couldn't before on an 8 inch driver. Between my NS10s and the LSR 308 I'm confident I can deliver a consistent and professional product without question. Thanks to Mike Harris once again for a great recommendation and making my recording life much easier!

Sweetwater Advice

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.

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.

Mitch Gallagher

On a budget? (Who isn't?) Looking for great monitors for your studio?? (Again, who isn't?) Then you definitely need to turn your attention to the new LSR305 and LSR308 monitors from JBL. The JBL LSR family of speakers has been highly regarded from the beginning, and these new members of the family only enhance that reputation. These are 2-way monitors with a 5-inch and an 8-inch woofer, respectively, driven by 82 and 112 watts of power, also respectively. They'll play plenty loud for most situations. The speakers are rear ported, which helps to enhance the low-frequency response. You're given controls for tailoring the highs and the lows to your room, as well as a level control on each speaker. Easy to set up, easy to use. What sets these speakers apart are the highs. JBL is using a brand-new waveguide, called the "Image Control Waveguide" on the high-frequency driver, and the results are spectacular. The LSR300 series speakers have some of the best imaging and smoothest high frequencies I've heard in a moderately priced speaker. I was sent both LSR305 and LSR308 models for this Hands On profile. The only real difference is the bass extension and the extra bit of oomph in the larger model. The highs and mids are quite similar. I played a wide range of material through the speakers, both reference tracks I always use for evaluating speakers and room acoustics and my own multitrack and stereo mix files. No matter what I played through them, they maintained their poise, with full bottom end, clear mids, and those wonderful smooth but detailed highs. When mixing, I had no problem getting the bass guitar to sit with the kick or to find the sweet spot for the vocal level or guitar solo level. I'm quite impressed with these monitors. They sound great regardless of price, but at their price point, they really are standouts.
