8" near-field studio monitor, ideal for home and project studios.

The LSR308, part of JBL's 3 Series studio monitors, is a 8" powered studio monitor delivering professional performance at an affordable price points. 3 Series Powered Studio Monitors are first to incorporate JBL's exciting new technology, the Image Control Waveguide. In conjunction with 3 Series high-performance transducers and system components, the Image Control Waveguide lets you hear detail and depth in recordings as you've never heard before.

The LSR308's 8" long-throw woofer and its 1" damped woven composite Neodymium tweeter are designed from the ground up to reproduce the powerful transients and micro dynamics of your mix. These drivers deliver impressive deep bass and smooth high frequency response beyond the range of human hearing.

JBL's Patented Slip Stream low frequency port design works in concert with the woofer to produce deep bass response at all playback levels. The double-flared shape of the port is precisely engineered for greater low-frequency extension and reduced turbulence.

Big Power, Big Sound
3 Series efficient Class D Amplifiers provide abundant power to deliver the output and dynamic headroom needed for the most demanding production styles

Professional Balanced Inputs
Balanced XLR and 1/4" (6 mm) TRS inputs give you the options you need to connect your 3 Series to any signal source while maintaining professional signal quality.

Selectable Input Sensitivity
The -10 dB/+4 dB sensitivity switch ensures compatibility with a broad range of signal sources, allowing you to connect the 3 Series to high output professional gear without any danger of input overload.

LF Trim and HF Trim "TRIM" switches for both the Low and High Frequencies give you excellent control over the 3 Series sound in "your" room. Use these to fine-tune the amount of bass and treble you hear to compensate for room acoustics, program material and your personal taste.

JBL Professional Reliability
Prior to becoming a production-ready design, each 3 Series model is subjected to JBL's tough 100-hour power test, in which the speaker is required to play continually at full output for 100 hours without failure. This demanding test ensures your 3 Series speakers will deliver years of reliable performance.

JBL LSR Design - Your Music Needs a Point of Reference
While most manufacturers take only a single on axis measurement of the speaker's performance, this doesn't tell how it will sound in your room. JBL's LSR Linear Spatial Reference design criteria requires seventy-two measurements yielding more than 1,200 times more data, enabling JBL to engineer a speaker that "sounds right" in any working space. With LSR design, 3 Series Studio Monitors deliver superior accuracy regardless of the size and shape of your room, so your mixes "hit their mark" when heard on any playback system.

  • Game Changer!

    As reviewed by Jason Aguja on 12/19/2013

    I picked these over Yamaha's HS80 (now reworked and named HS8) for a less boomy low end, extended but not hyped and better mids response. You really don't need to add a subwoofer with these; they're (to my ears) as full range as it gets with an 8" woofer and 1" tweeter. Lower and Upper midrange is definitely more present than the HS80/HS8 and JBL's new waveguide on the tweeter makes even off-axis listening more accurate than others. I've worked on Focal Twin6's (higher end monitors) and the clarity and flatness of response is comparable. I also have these JBL's next to my Yamaha NS10's and side-by-side they still provide midrange clarity and fast transient response I'm used to on the NS10's (not bad for the Class D Amps in JBL's). They can get loud and not choke and to my ears and I'm sure there is a limiter in the circuit to protect you. I'm extremely happy with these, they're flat, not fatiguing on the ears while mixing, have extended low end and no port noise and they are affordable. They translate the dynamics of classical and jazz music as well as deliver heavily compressed/brickwall limited EDM and Hip-Hop with ease. They've beat most if not all monitors in this class/price range. I recommend them to all serious producers/engineers and musicians looking for affordability and true quality.

  • The Real Deal

    As reviewed by CURTIS FALLIS on 4/19/2014

    I rarely take the time to write up a review on gear but I just had to throw in my opinion here. I read probably EVERY review I could hunt down online about these monitors well before I purchased them and the hype was so great it made me rethink getting the KRK's which I pretty much had my mind made up on. I had already heard the KRK's and considered them to be pretty solid for this mid-price range group of monitors. So I went down to GC and sat for about 3 hours flipping the little switches listening to every monitor they had giving a very solid listen and I know this is such a subjective thing but to me the JBL's just blew everything away. The hype is legit. I have them running out of a KRK 10s sub so they are crossed over and therefore I'm not relying on them for my low end, but they do pump some serious low end frequencies. The high/mid stereo spread is perfect. I have them propped up on the ISO Acoustics L8R200 stands and I also have my sub on the ISO Acoustics sub stand as well. Man what a difference those stands make! So if you're in that $500 price range do yourself a favor and consider the JBL's. I couldn't be happier.

  • Great Monitor

    As reviewed by LARRY NEWMAN on 12/15/2013

    Great sound, very good response to all of my synthesizer range. I am not a studio engineer, but they sound great to me. Good bass, highs are sharp. Easy to listen for hours without feeling like your ears are beat up.
