The JBL LSR305 is a bi-amplified studio monitor with magnetically-shielded 5” low frequency transducer and 1” soft-dome high frequency transducer and image control waveguide. This monitor's bi-amped design features two Class 'D' amplfiers, sending 41 Watts each to the woofer and tweeter. The LSR305 also features balanced XLR and 1/4” TRS inputs with detented level control and HF & LF trim controls.

Image Control Waveguide
The Image Control Waveguide was developed for JBL’s new flagship M2 Master Reference Monitor and with the introduction of the JBL 3 Series, is now included for the first time in an affordable, compact reference monitor. The patent-pending design of the Image Control Waveguide precisely controls the sound emanating from the speaker in the vertical and horizontal planes ensuring the presentation at the listening position is neutral and accurate

Legendary JBL Transducers
The 3 Series long-throw woofer and its 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
The Slip Stream port 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" 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 -10dB/+4dB 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 Switches
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.
