JBL Professional LSR305

JBL Professional's new 3 Series studio monitors—the LSR305 ($199.99 MSRP) 5-inch powered studio monitor and the LSR308 ($325 MSRP) 8-inch powered studio monitor—are the first to incorporate JBL’s patent-pending Image Control Waveguide. 3 Series monitors are designed to deliver exceptional imaging and detail in any listening environment for music production, post-production and broadcast production customers who work in stereo and surround sound formats.

3 Series models are packaged in 5-Color cartons that explain the technology and feature set in detail. The LSR305 promises a response of 43 to 24k Hz and a peak SPL of 108 dB, while the LSR308 features a response of 37 to 24k Hz and a peak SPL of 112 dB.

Leveraging new technology developed for JBL’s flagship M2 Master Reference Monitor launched earlier this year, the 3 Series features JBL’s patent-pending Image Control Waveguide, which enables the listener to hear greater depth and ambience in recordings. Surrounding the high frequency tweeter, and located directly above the woofer, the waveguide precisely controls the sound emanating from the monitor in the vertical and horizontal planes. With a complex contour employing tiny, meticulously engineered ridges, the waveguide optimizes the phase relationship of the loudspeakers, and also the blend of directed and reflecting sound arriving at the listening position.

The product of intensive R&D, the waveguide design allows subtle detail to be heard, even in a dense mix. The waveguide produces a wide stereo panorama with a rock-solid phantom-center image. In addition, the waveguide enables 3 Series models to deliver neutral sound across an unusually large working space, regardless of room acoustics, eliminating the need for the customer to be positioned directly in front of the monitors when making critical adjustments to the mix.

As the sound generating engines, the 3 Series’ long-throw woofer and its damped woven composite tweeter are designed from the ground up to reproduce the powerful transients and micro dynamics of any mix. According to JBL, these drivers promise deep bass and smooth high-frequency response "beyond the range of human hearing." JBL’s patented Slip Streams 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. Class-D amplifiers provide abundant power to the drivers to deliver the output and dynamic headroom needed for the most demanding production styles.

Each 3 Series model incorporates a range of features to integrate the loudspeakers into a broad range of environments including multiple inputs, a detented volume control and an input sensitivity switch for compatibility with professional and consumer equipment.

Using 3 Series low and high-frequency “Trim” switches, the user can tailor the loudspeaker’s response to compensate for room acoustics, program material and personal tastes.

To ensure years of reliable performance, 3 Series prototypes were subjected to JBL’s 100-hour power test, in which the loudspeaker is required to play continually at full output for 100 hours without failure.
