Product Description for the JBL LSR308
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 LSR305’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.
