JBL's LSR308 2-Way Powered Studio Monitors give you professional-level studio monitoring with technology borrowed directly from its flagship M2 Master Reference Monitor!

JBL’s L Series sets a new bar for studio control monitors and offers accurate, efficient and natural response with high detail and imaging usually associated with monitors costing hundreds more, thanks in no small part to JBL’s patent-pending Image Control Waveguide technology that’s borrowed directly from its flagship M2 Master Reference Monitor.

At the heart of the LSR308 is JBL’s Image Control Waveguide that accurately governs the audio on both the horizontal and vertical planes to make sure the end result is a true and neutral audio depiction of the program material. To achieve this end, the LSR305 employs a 1” silk-dome, damped woven composite Neodymium tweeter coupled with an 8 inch, long throw woofer that have been engineered from the get-go to reproduce all the dynamics and nuances of your mix. As an added bonus, not only will it deliver deep, impressive bass, but also smooth high frequency response, even well beyond the range of human hearing!

Another patented JBL technology to find its way into the LSR 308 is its Slip Stream low frequency port design that works in conjunction with the woofer to produce deep bass response regardless of where the playback level may be set. The double-flared shape of the port is precisely engineered for greater low-frequency extension and reduced turbulence.

Driving the whole enchilada is JBL’s high-efficient 112 Watt Class-D bi-amplified power plant (56w HF + 56w LF) that is more than capable of delivering the correct output and dynamic level needed to create big sounding, yet highly accurate mixes in any production environment.

And leaving no stone unturned, JBL is acutely aware that every room acoustic signature is different and has developed a system to compensate for the myriad of room configurations and types with its integrated Low Frequency and High Frequency Trim switches. These both offer excellent control over the 3 Series sound in “your” room and you can use these to fine-tune the amount of bass and treble content you hear in order to adjust for room acoustics, program material and your personal taste.

Professional Balanced Inputs
Balanced XLR and 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.

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.
