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!

Pushing 4 Years

I am not a music maker, but I listen to music (Hip Hop, Jazz, Classical, Metal, Folk, you name it) continuously and I love my speakers. I saved up over the first year of college and bought these for myself and they are without a doubt my favorite posses ion. Due to my bass addiction, I added the LSR310s, but if you want to use them for production I would not recommend this as the 8'' woofer on the 308's is plenty to see whats there. Lastly, the waveguide surrounding the tweeter really works and makes the speakers' sweet spot much bigger. 4 years later, I could not be happier with these speakers :)

Great Studio Monitors

i went in to Sweetwater today to grab the Yamaha HS8's and the employee told me before buying to listen to the KRK Rockits & these JBL LSR's and after about 3 or 4 songs later, switching through the 3 speaqker sets, i was convinnced that these were better, good lows & mids and the highs came in so well over the bass. I love my purchase

Little Speaker! Big Sound!

I love these monitors! Small package but a big sound with plenty of punch! I bought these for my home studio and I love them.

Very, Very Happy....Finally

Well - I've been on a mission to find the right set of monitors for me that work well in my smallish control room. I mainly use ns-10's, but have been looking for something that complements the yammy's. What i mean is - i wanted something that gives a different audio perspective compared to the ns-10's but still makes sense. I had a pair of proac 100's - i liked them, but it was still hard to make decisions about the low end - sold those. I went through a bunch of stuff after those, and then bought a pair of Focal twin6 be's. I really like the Focals', but i found them to not work very well in my room - i have to be pretty close to the speakers - the focal's worked better the further i got back from them. I would probably have kept them if i was in a bigger room. Got a tip about these JBL's from an engineer that i respect and took a shot on them. I put them up and within about a 2 hour listening session between them, the Focal's and the ns-10's - i put the Focal's up for sale and put up the JBL's in their spot and have never looked back. My mixes are translating better than ever - i trust what i'm hearing in the low end, and switching between them and the ns-10's - i have this perfect thing. The JBL's are great for hearing the top and bottom - i can get a good balance going very quickly - when i switch to the ns-10's, it's like a microscope on the midrange. I am very happy with my monitoring rig with these speakers. They have an incredibly large sweet spot and it's great when i have the bands/artists come in and listen because almost no matter where they are sitting in the room - the imaging is good and there's not like little hot spots here and there where the mix sounds totally different from two feet over. I love them.

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.
